WeatherWhen

Know exactly what to pack and when to go. WeatherWhen shows you the typical conditions for any destination, month by month, so you can plan trips with confidence long before you leave.

Instead of a live forecast that only helps once you have arrived, WeatherWhen answers the question that actually matters when you are planning: what is it usually like there in May? In December? It turns decades of records into a clear, at-a-glance picture of average highs, average lows, and rainfall for all twelve months.

WHY YOU WILL LOVE IT

- Find the ideal time to go. The app highlights the most pleasant months for each place, balancing comfortable temperatures against rainfall.
- Compare your shortlist. Save the places you are considering and swipe between them to see how they stack up for the same month.
- See the latest trend. Switch between a 30-year average and the most recent years to see how conditions have been shifting.
