How it works
-
You enter your journey.
Start location, destination, and the times you expect to be outside. -
Locations are resolved precisely.
We convert place names into coordinates (and let you choose if there are multiple matches). -
Hourly weather is checked.
We use official hourly forecasts for rain probability and rainfall amount. -
High‑risk moments are analysed.
We focus on the times you’re most likely to get wet: leaving, arriving, and heading back out. -
A simple decision is made.
If meaningful rain is likely at any point, we recommend taking an umbrella.
Forecast data is provided by Open‑Meteo. Results are cached in your browser to reduce unnecessary requests. No accounts, no tracking, no personal data stored.
Should I bring an umbrella today?
This tool helps you decide whether you need an umbrella today by checking hourly rain forecasts for the exact times you’ll be outside — not just the general weather for the day.
Instead of relying on a daily rain icon, we look at key moments in your journey: when you leave home, when you arrive at your destination, and when you head back out. If meaningful rain is likely at any point, we’ll recommend taking an umbrella.
How is this different from a normal weather forecast?
Most weather apps show a broad daily summary. This site focuses on practical decisions — whether rain is likely during the short windows when you’re actually exposed to the weather.
It’s especially useful if rain is forecast “later”, “on and off”, or with uncertain timing. If you’re asking yourself “will it rain before I leave?” or “do I need an umbrella today?”, this tool is designed for exactly that.
