Your iPhone's Weather app is receiving its biggest update yet in iOS 16. With Apple finally incorporating its Dark Sky purchase into Apple Weather, you'll see more information for each location's forecast. Plus, there are a few surprises to be excited about, such as the ability to add more cities to track.
Apple won't release iOS 16 to the general public until this fall after developer and public beta testing. Still, you can see below how useful it will be if you don't want to install the beta yourself. If that's the case, there are still a lot of hidden customizations you can tweak for your Weather app right now, all of which will still apply in iOS 16.
Before iOS 16, you could only monitor up to 20 locations in the Weather app. A prompt would tell you to remove other places before you could add more. Now you won't see that prompt until you reach the new 50-location limit (your current location plus 49 more).
With the new Lock Screen wallpaper system, you can have multiple Lock Screens designs you can switch between whenever you want. And on each Lock Screen wallpaper you design, there are widgets you can add. There are eight different Weather widgets for both over and under the time: Air Quality, Conditions, Moon Events, Rain, Sun Events, Temperature, UV Index, and Wind.
You can also add a weather wallpaper that updates in real time when the weather conditions change in your local area. There's only one weather-related design; you can select it when setting up a new Lock Screen wallpaper. The Home Screen wallpaper will automatically match it by default. You can change the Home Screen wallpaper while keeping the live weather one on the Lock Screen only. There are also five astronomy wallpapers that update with astronomical conditions.
Whenever meteorological agencies issue a local severe weather notice in select regions, Weather can send you notifications about it. It's on by default, but you can toggle off "Severe Weather" in Weather's in-app notification settings.
Severe weather information is available from The Weather Channel for Australia, Canada, Japan, the United States, and most countries and regions in Europe. Some users might receive severe weather alerts from various meteorological agencies through Apple Weather. Severe weather information is available from national weather services for Brazil, India, Mexico, and Thailand. Severe weather information is available from QWeather for China mainland.
There's also a "Next-Hour Precipitation" toggle in Weather's in-app notification settings, which is on by default. You can turn it off, but you'll get helpful rain and snow alerts for the next hour if you keep it on. Weather would already send you a notification when rain or snow was starting or stopping, and that should continue.
Next-hour precipitation forecasts and precipitation notifications are available for Ireland, the United Kingdom, and the United States. The information is provided by Apple using data from national weather services.
Like in iOS 15, the Weather app lets you toggle on or off alerts for each location in the in-app notification settings. Instead of just a single toggle for each city, there are now two for the new "Severe Weather" and "Next-Hour Precipitation" alerts, but only in supported locations.
You can now tap on any module in the Weather app to open up a detailed view with more information. Apple populates the view with data from the Dark Sky weather service that Apple acquired in 2020, which is built into the new WeatherKit API for third-party developers (see below for more info).
Before, you could expand only the Air Quality module, but now you can also expand the Hourly Forecast, 10-Day Forecast, UV Index, Wind, Rainfall, Feels Like, Humidity, Visibility, Pressure, and Sunrise/Sunset modules. For example, the Sunrise/Sunset module now expands to show a bigger chart, key times (first light, sunrise, sunset, last light, and total daylight), average times for previous months, etc.
You could already see a map of the air quality for a location by opening the Map module, but now there's one baked right into the expanded Air Quality module.
The Hourly Forecast and 10-Day Forecast modules are likely the most-used tools the Weather app has, but you could only see limited information in a single graph for each. For example, the 10-Day Forecast module only shows the day, conditions icon, low and high temperatures, and temperature range colors.
You still see those in iOS 16, and you can tap on them to see more detailed data. But tapping the UV Index, Wind, Rainfall, Feels Like, Humidity, Visibility, and Pressure modules will also show hourly and 10-day predictions.
You don't have to tap each module individually to open its hourly and 10-day forecasts — just use the drop-down selector in the expanded view to switch between Temperature, UV Index, Wind, Rainfall, Feels Like, Humidity, Visibility, and Pressure.
In iOS 15, when you open a location's map in Weather from the Map module or Map icon in the bottom corner, you'll see the "12-Hour Forecast" player controls for precipitation. The map auto-syncs with the timeline so you can see the cloud movement. If you don't see it, tap the layers icon and select "Precipitation."
What's different in iOS 16 is that there's also a "Next-Hour Forecast" view. For me, it always shows it first, and I have to tap "Next-Hour Forecast" in the controls to switch to the 12-hour option.
Apple changed the "Report an Issue" link again in one of iOS 16's smallest changes. First, it was just a simple three-word line of text at the bottom of the current location's weather. Then, it became its own module in iOS 15.5, complete with a description, but you had to tap "See More" to submit reports.
Now, in iOS 16, the "See More" link is gone, and tapping anywhere on the module will open the reporting feature. It makes sense since the rest of the modules work similarly — tap anywhere on the module to expand it.
In June 2020, Craig Federighi said that Apple could easily scale up its existing iPhone Weather app for iPadOS but that it would rather build a great iPad Weather app than resort to a simple scaled-up app. That time has finally come.
I could see how scaling up the iOS 15 Weather app for iPadOS would be less than thrilling, but now that iOS 16 has incorporated more data and graphs, a scaled-up version makes sense for iPadOS 16.
Third-party apps and services can now leverage Apple Weather's data with the new WeatherKit API powered by Dark Sky's forecast technology. Apple acquired the Dark Sky weather service in 2020.
WeatherKit is powered by the all-new Apple Weather service, a state-of-the-art global weather forecast that provides all of the data you need to power your app with timely, hyperlocal weather information. This enables your app to offer current weather conditions and 10-day hourly forecasts for temperature, precipitation, wind, UV Index, and more. Minute-by-minute precipitation for the next hour and severe weather alerts are available for select regions.
WeatherKit provides up to 500,000 API calls every month with an Apple Developer membership, but anything over that will cost anywhere from $49.99 to $999.99 per month.
