Partly Sunny has been featured by Apple, MacStories, AppAdvice, and Lifehacker.
Partly Sunny “introduces a robust, beautiful new way to view weather information. […] What’s immediately striking about Partly Sunny’s design is that it feels designed to belong in iOS. It’s an app that feels built by Apple if the company decided to make a massive iterative change to its own stock Weather app.” – Jake Underwood, MacStories
“If you are looking for minimalism in your weather app, then Partly Sunny will satisfy your cravings. […] Partly Sunny offers the information you need in a concise and flexible way.” – Christine Chan, AppAdvice

Version 1.4.11
This update has some radar-map additions & changes and some bug fixes.
Radar Changes
Partly Sunny’s radar-data provider made some changes that resulted in the map layers for severe-weather warnings, storm cells, and advisories not fully loading their data. Unfortunately I had to remove the advisories layer as a result. The warnings and storm-cells layers, though, are still available but are updated to use slightly different data.
Radar Additions
There are also some new map layers. For US locations, there’s a new radar & clouds layer. For locations in Europe, the radar & warnings layer is now also available. And for locations worldwide, there’s a new temperatures layer and wind-speeds layer.
Also, when the warnings layer is selected, there’s a new button in the radar view to swap the layer positions. By default, precipitation radar is on top of the warnings layer, but to better see the warnings that may be covered by the radar layer, you can swap the layers so warnings are on top.
Apple Weather Fix
The issue where Apple Weather forecasts might not display properly for some users should be fixed. Turns out working with dates, times, and time zones is… hard. Hahaha. (Thanks, Michael!)

Partly Sunny version 1.4.9
Updated At: 2023-04-26
Changes: Apr 26, 2023
Version 1.4.9
Part Two of the post-Dark-Sky update! Partly Sunny is now powered by Apple Weather—which brings back hourly graphs for each day this week and yesterday’s weather!
Apple Weather
Forecasts in Partly Sunny are now powered by Apple Weather, Apple’s replacement for Dark Sky. For Partly Sunny Club members, if you prefer OpenWeather forecasts, you can change data providers in Settings.
Hourly Graphs
When Apple Weather is selected as the data source, hourly graphs are back in Day View. So when you select a day in Week View, forecast details for the day once again include an hourly graph of temperatures & conditions. (And as a reminder, you can tap anywhere on the graph to change the data point, and you can touch & hold to show details for the hour and then drag left & right to see other hours.)
Yesterday’s Weather
Also when Apple Weather is selected, Week View can once again show yesterday for quick comparisons. Enable it in Settings > Daily Forecasts. (Partly Sunny Club required.)
Day View
In Day View, new back & forward buttons show the previous & next days without having to go back to Week View to select a new day. You can also swipe left & right to change days and use the Left Arrow & Right Arrow keys on an external keyboard.
Text Summaries
Text summaries for today & tomorrow are expanded and a little more specific in some cases. For example, they now support summaries like “Partly sunny today and tomorrow, and light rain tomorrow night.” and “Partly sunny today, and light rain tonight and tomorrow morning.”

Partly Sunny version 1.4.8
Updated At: 2023-03-31
Changes: Mar 31, 2023
Version 1.4.8
This update moves Partly Sunny to a new data provider. Forecasts were powered by Dark Sky, but Apple is sadly shutting it down, so now forecasts are powered by OpenWeather (Apple Weather support will come in a future update).
Partly Sunny was really built around and for Dark Sky weather data, so with a new data provider, unfortunately some things are different or temporarily missing because they aren’t supported by OpenWeather:
• Today View can only show up to 48 hours of hourly data
• Week View can’t show yesterday’s weather
• Day View doesn’t show hourly data for the selected day
• Time Machine isn’t available
I’m hopeful, though, to bring these features back in a future update.
Radar Updates:
Previously, precipitation radar was only available in the US, the UK, parts of Canada & Europe, and a few other places. Now it’s available for locations worldwide.
Also available worldwide is a new layer to show tropical storms, hurricanes, and cyclones.
For US locations, there’s a new layer to show storms and storm trajectories.
And for locations in Canada and Europe, there’s a new advisories layer to show advisories for rain, snow, flooding, wind, etc.
Day View Updates:
Day View doesn’t show hourly data currently, but it does now show temperatures throughout the day and automatically shows all available conditions. Plus more detailed moon data is available again with an updated moon API from the U.S. Naval Observatory.

Thank you to everyone at Dark Sky for all your work over the years. Not only did you power the forecasts in Partly Sunny for so long, you helped power my dream several years ago of learning how to make an iPhone app and becoming an app developer. Without the easy-to-use Dark Sky API, I probably wouldn’t have built Partly Sunny back then. So thank you for helping me on my journey to where I am today.
And thank YOU for using and supporting Partly Sunny! Even when the weather isn’t enjoyable, I hope you enjoy checking the weather with Partly Sunny. Stay tuned for more updates later this year!

Partly Sunny version 1.4.6
Updated At: 2021-11-16
Changes: Nov 16, 2021 Version 1.4.6
It’s been a while, but I’m back with another Partly Sunny update! This update is focused on fixes—and lots of them! Next, I plan on adding Home Screen widgets and updating the Shortcuts support.
What’s fixed in this update:
• Layout and sizing issues on iOS and iPadOS 15 are fixed.
• The calendar button to check past or future weather correctly shows the date picker again.
• Keyboard shortcuts that use arrow keys work on iPadOS 15.
• In Today View, the occasional extra space between the hourly graph and the toolbar is fixed.
• Week View on iPad in landscape orientation uses vertical bars instead of horizontal bars.
• Previewing a day in Week View on iPhone 8/SE properly sizes elements in the preview.
• Radar and alerts views use standard iOS modals.
• Buttons and other elements have iPadOS pointer effects.
As part of the effort to update the app and prepare for new widgets and Shortcuts actions, Partly Sunny now requires iOS 14 or higher.

Partly Sunny version 1.4.5
Updated At: 2019-11-16
Changes: 16 Nov 2019 Version 1.4.5
This update has a few more iOS 13 goodies plus some fixes!
NEW: If you’re on iOS or iPadOS 13, there are new context menus in Locations View and Week View. Tap and hold on a location or a day for a detailed preview of the forecast. (This is similar to the 3D Touch peek & pop previews in iOS 12 and lower, but they also work on iPad now too. If you have a 3D Touch device on iOS 12 or lower, you can still peek & pop.)
FIX: Some things (like the current location icon in Siri Shortcuts) weren’t set to the correct color when the app is set to follow the iOS 13 system dark mode appearance, but now they are.
FIX: On iPadOS 13, the widget no longer shows too many squished cells.
FIX: The current pressure indicator (the trend arrow looking three hours ahead) in Today View is back, and it will now appear in Siri Shortcuts too when the current pressure is shown.
NEW: iOS 13’s new inset grouped table view style is now used throughout settings and settings submenus as well as in the views to edit the locations list and locations.
