Do I Need An Umbrella?

How it works

1. You enter your journey.
   Start location, destination, and the times you expect to be outside.
2. Locations are resolved precisely.
   We convert place names into coordinates (and let you choose if there are multiple matches).
3. Hourly weather is checked.
   We use official hourly forecasts for rain probability and rainfall amount.
4. High‑risk moments are analysed.
   We focus on the times you’re most likely to get wet: leaving, arriving, and heading back out.
5. A simple decision is made.
   If meaningful rain is likely at any point, we recommend taking an umbrella.
