Leeds Festival Weather for Android
When the festival is further than 7 days away it displays the expected weather for the festival site in daily intervals but once the festival is less than a week away the forecasts show each day in 3 hour intervals telling you what weather you can expect this year.
You can also follow the local weather radar at the festival so you can see any rainfall around the site and what direction it is moving in. In short, you have the perfect app to follow the weather and make sure you don't get caught out.
Better take your wellies anyway, but if you are off to Leeds this year then this is the must have app!
