While we've been able to change the weather in Sword and Shield, the method is a little different for the expansion.
Here's how to change the weather.
How To Change The Weather In Pokemon: Isle of Armor
If you're wondering why you'd want to change the weather in the game, it's because the Pokemon available in the Wild Area will change dependant on the climate.
In the base game, you can adjust the date on your console to affect the weather, with the first day of each month changing to a specific weather pattern.
In the Isle of Armor, things are slightly different because the weather is based on the fifteenth day of each month.
In your console's settings menu, head into the System and then Date and Time. Turn off internet synchronization for the clock, and then adjust to the following:
- Jan 15 - Fog
- Feb 15 - Overcast
- March 15 - Clear
- April 15 - Rain
- May 15 - Sun
- June 15 - Rain
- July 15 - Thunder
- Aug 15 - Thunder
- Sept 15 - Clear
- Oct 15 - Fog
- Nov 15 - Clear
- Dec 15 - Sun
