Why the iPhone Weather App Is Better Than You Think
The Weather app that comes with your iPhone is easy to underestimate. It looks simple: a temperature, a sunny icon, a list of days. But behind that clean design is a surprisingly powerful weather tool, with hourly forecasts, rain maps, severe weather alerts, air quality data, and detailed information about wind, humidity, UV, and visibility. Most of it is free, built in, and already on your phone.
This guide walks you through everything the iPhone Weather app can do, with a focus on the two features people ask about most: the hourly forecast, which tells you what the weather will do hour by hour, and the rain maps, which show you exactly where rain is falling and where it is heading. You will also learn how to add and manage locations, set up severe weather alerts, read the detailed weather data, and use widgets so the forecast is always one glance away.
How to Read the Main Weather Screen
Open the Weather app and you see your current location at the top, with the current temperature in large numbers, a short description like “Partly Cloudy”, and the day’s high and low. Below that is the hourly forecast, a horizontal strip you can scroll through, showing the temperature and conditions for each hour. Below that is the 10-day forecast, a list of days with icons, rain chances, and high and low temperatures.
Scroll down further and you find a set of small cards, each showing one piece of detail: UV index, sunrise and sunset times, wind speed and direction, precipitation totals, feels-like temperature, humidity, visibility, and air pressure. Tap any card and it expands to show a graph or more detail, with an explanation of what the number means. This is the part of the app most people never scroll to, and it is where the useful information lives.
If your phone shows the wrong location, or a location you do not recognise, tap the menu icon at the bottom-right, which looks like three lines, and check the list of saved locations. Your current location is marked with a small arrow. Tap it to open it, or swipe left on any location to delete it.
How to Use the Hourly Forecast
The hourly forecast is the most practical part of the Weather app, because it answers the questions you actually ask during the day: will it rain at lunchtime, do I need a jacket this evening, and when does the temperature drop.
Step 1: Find the hourly strip. Near the top of the main screen, just below the current temperature, is a horizontal row of hours. Swipe left to scroll through the next 24 hours. Each hour shows the time, a weather icon, and the temperature. Hours with rain show a small blue percentage underneath, which is the chance of rain in that hour.
Step 2: Tap an hour for detail. Tap any hour in the strip and a detail card opens, showing the temperature, feels-like temperature, wind, humidity, and precipitation chance for that hour. This is useful when you are deciding whether to go for a run at 6pm or wait until 8pm, because the difference between two hours can be a few degrees and a rain shower.
Step 3: See the hourly forecast as a list. If you prefer a vertical list to a horizontal strip, tap the hourly forecast section and it opens a full-screen view with each hour on its own row, showing temperature, rain chance, wind, and humidity. This view is easier to scan when you are planning a whole day, because you can see 12 hours at a glance instead of scrolling sideways.
Step 4: Use the hourly forecast to plan around rain. The rain percentage in the hourly view is the chance of rain in that hour, not the amount of rain. A 30 percent chance means rain is possible but not likely, while an 80 percent chance means you should expect to get wet. Check the hours around your plans, not just the daily summary, because a day that says “rain” in the 10-day forecast might only rain for one hour in the afternoon.
How to Use the Rain Maps
The rain map is the Weather app’s most underrated feature. It shows a live radar map of rain, snow, and storms, so you can see exactly where precipitation is falling right now and which way it is moving. This is far more useful than a rain percentage, because it tells you whether the rain is heading toward you or away from you.
Step 1: Open the precipitation map. On the main weather screen, scroll down to the precipitation card, which shows a small map with rain areas in blue and green. Tap it, and the map opens full-screen. You can also tap the map icon at the bottom-left of the main screen, which looks like a folded map, to open the full map view directly.
Step 2: Understand what the colours mean. The map uses colour to show how heavy the rain is. Light blue or green means light rain or drizzle. Yellow and orange mean moderate to heavy rain. Red and purple mean very heavy rain or a storm. White or pink usually means snow or sleet, depending on the temperature. The map updates every few minutes, so what you see is close to live.
Step 3: Play the animation to see where rain is heading. At the bottom of the map screen is a play button and a timeline. Tap play, and the map animates the last few hours of rain movement, so you can see the direction and speed of a weather system. If a band of rain is moving from west to east and you are to the east of it, you know it is coming. If it is moving away, you know the worst is over. This is the single most useful thing the map does, and it takes five seconds to check.
Step 4: Zoom and move the map. Pinch to zoom in and out, and drag to move the map to another area. You can check the weather at your destination before you travel, which is useful if you are driving to another city or flying somewhere. The map covers your saved locations too, so you can check rain at home and at your holiday destination without changing anything.
Step 5: Switch between map layers. The map icon at the top-right lets you switch between precipitation, temperature, and air quality layers. The temperature layer shows a colour-coded map of hot and cold areas, which is useful for seeing a heatwave or a cold front. The air quality layer shows pollution levels, which matters if you have asthma or you are planning outdoor exercise.
How to Add and Manage Locations
The Weather app can track as many locations as you like, and switching between them takes one tap. This is useful for checking the weather at home, at work, at a holiday destination, or where your family lives.
Step 1: Add a location. Tap the menu icon at the bottom-right, then tap the search bar and type a city, town, or postcode. Tap the location in the results, and it is added to your list. You can also add a location by tapping a place on the map, though searching by name is faster.
Step 2: Reorder your locations. In the locations list, tap and hold the three-line handle next to a location and drag it up or down. Put the places you check most often at the top, so they are the first ones you see.
Step 3: Delete a location you no longer need. Swipe left on a location in the list and tap Delete. Your current location, marked with an arrow, cannot be deleted, because it is set by your phone’s GPS, but every other location can be removed.
Step 4: Turn location access on or off. The Weather app needs location access to show your current weather. If it shows the wrong city, go to Settings, then Privacy and Security, then Location Services, then Weather, and check that it is set to “While Using the App” with Precise Location on. If you prefer not to share your location, turn it off and add your city manually instead.
How to Set Up Severe Weather Alerts
Severe weather alerts warn you about dangerous conditions like heavy rain, storms, extreme heat, or high winds. They arrive as notifications, and they are worth turning on, because they are the one feature of the Weather app that can genuinely keep you safe.
Step 1: Turn on notifications for the Weather app. Go to Settings, then Notifications, then Weather, and turn on Allow Notifications. Choose how you want them to appear: as banners, on the lock screen, and in Notification Centre. Severe weather alerts are time-sensitive, so allow them to appear on the lock screen.
Step 2: Turn on severe weather alerts inside the app. Open the Weather app, tap the menu icon, then tap the three-dot menu at the top-right, then Notifications. Turn on Severe Weather for your current location and for any other location you care about. You can also turn on “Next-Hour Precipitation”, which sends a notification when rain, snow, or hail is about to start or stop in the next hour. This is the alert that tells you to grab an umbrella before you leave the house.
Step 3: Understand what the alerts cover. Severe weather alerts come from your country’s national weather service, so what they cover depends on where you are. In the United States they include tornado warnings, flash flood warnings, and extreme heat warnings. In the United Kingdom they include Met Office weather warnings. In other countries the coverage varies, and in some places the alerts are not available at all. If you do not see the option, your region does not support it yet.
How to Read the Detailed Weather Data
Below the 10-day forecast is a set of detail cards, and each one is worth understanding, because they turn a vague forecast into something you can act on.
UV index. This tells you how strong the sun’s ultraviolet radiation is. A UV index of 0 to 2 is low, and you do not need sun protection. A UV index of 3 to 5 is moderate, and you should wear sunscreen if you are outside for a long time. A UV index of 6 to 7 is high, and you should wear sunscreen, a hat, and sunglasses. A UV index of 8 or above is very high, and you should avoid the midday sun if you can. Tap the card to see the UV level hour by hour.
Sunrise and sunset. This shows the times the sun rises and sets, and the length of the day. It is useful for planning photography, outdoor exercise, or a walk home before dark. The card also shows the time of first light and last light, which are often more useful than the sunrise and sunset times themselves.
Wind. This shows the wind speed and direction, with a compass that points where the wind is coming from. It also shows gusts, which are the short bursts of stronger wind that matter more than the average speed when you are cycling, sailing, or putting out washing. A wind speed of 10 mph is a light breeze, 20 mph is noticeable, and 30 mph or more is strong enough to make walking difficult.
Precipitation. This shows how much rain is expected in the next 24 hours, in millimetres or inches, and how much has fallen in the last 24 hours. It also shows the chance of rain. A small amount of rain, like 1 mm, is a light shower. Ten millimetres is a proper rainy day. Fifty millimetres is a flood risk in many places.
Feels like. This is the temperature your body actually feels, taking wind and humidity into account. On a windy day, the feels-like temperature can be several degrees colder than the actual temperature. On a humid day, it can feel several degrees hotter. When you are deciding what to wear, the feels-like temperature is usually the more useful number.
Humidity, visibility, and pressure. Humidity tells you how much moisture is in the air. High humidity makes hot weather feel hotter and can make it hard to sleep. Visibility tells you how far you can see, which matters for driving in fog. Air pressure tells you whether the weather is likely to improve or get worse: falling pressure usually means rain is coming, while rising pressure usually means the weather is clearing up.
How to Use Weather Widgets
Widgets put the forecast on your home screen or lock screen, so you can check the weather without opening the app at all. This is the fastest way to use the Weather app, and it takes a minute to set up.
Step 1: Add a home screen widget. Long-press an empty area of your home screen, tap the plus icon at the top-left, search for Weather, and choose a widget size. The small widget shows the current temperature and conditions. The medium widget adds the hourly forecast. The large widget adds the 10-day forecast. Pick the size that fits your home screen, and drag it into place.
Step 2: Add a lock screen widget. On iOS 16 and later, you can add weather widgets to your lock screen. Long-press the lock screen, tap Customise, tap the widget area, and add the Weather widget. You can choose to show the temperature, the conditions, or the rain chance. This is the fastest weather check there is: glance at your phone and you know whether you need a coat.
Step 3: Choose which location the widget shows. By default, a widget shows your current location. If you want it to always show a specific place, long-press the widget, tap Edit Widget, and choose a location. This is useful if you want a widget for your holiday destination while you are travelling, or for your home city while you are away.
Common Problems and How to Fix Them
The weather is wrong or out of date. Pull down on the main screen to refresh the forecast. If it still looks wrong, check your location settings and make sure Precise Location is on. Weather data comes from Apple’s weather service, and it is usually accurate, but it can be wrong in areas with few weather stations. If the app says it is sunny and it is raining outside, trust your eyes.
The rain map is not available. The precipitation map is not available in every country. If you tap the map and see a message saying it is not available, your region does not support it yet. The hourly forecast and the 10-day forecast still work, and you can use a third-party radar app for rain maps in the meantime.
Notifications are not arriving. Check that notifications are on for the Weather app in Settings, and that Severe Weather is turned on inside the app. Also check that you have not turned on a Focus mode that silences notifications. Severe weather alerts should break through most Focus modes, but it is worth checking if you use Focus regularly.
The app shows a location you do not recognise. This usually happens when your phone’s GPS picks up a nearby town instead of your exact location, or when you have location access set to approximate instead of precise. Add your city manually and delete the wrong location, or turn on Precise Location in the Weather app’s location settings.
Frequently Asked Questions
Is the iPhone Weather app free? Yes. It is built into iOS, it has no ads, and all of its features, including the rain maps and severe weather alerts, are free. You do not need a subscription or an account.
How accurate is the iPhone Weather app? It is generally accurate for the next 24 to 48 hours, and less accurate further ahead. The 10-day forecast is a guide, not a promise, and it changes as new data comes in. Check the forecast again the day before an important plan, rather than trusting a forecast made a week earlier.
Where does the data come from? Apple uses its own weather service, which combines data from national weather services, weather stations, and other sources. The app does not say which source it uses for your location, but the data is comparable to other major weather apps.
Can I see the weather for a place without adding it? Yes. Use the search bar in the locations list to look up any city, and you can view its weather without adding it to your list. It is only added permanently when you tap it from the search results and it appears in your saved locations.
Final Thoughts
The iPhone Weather app is much more than a temperature and an icon. The hourly forecast tells you what to expect hour by hour, the rain maps show you where precipitation is and where it is going, the severe weather alerts keep you safe, and the detail cards explain the numbers behind the forecast. Spend five minutes setting up your locations, your alerts, and a widget, and the app becomes a tool you use every day without thinking about it. Next time you are wondering whether to take an umbrella, open the rain map, press play, and watch where the rain is heading. That is the whole guide in one habit, and it is worth more than any forecast summary.
