Will It Rain Today? Rain Risk by City
A rain probability on its own is not a decision. Sixty percent chance of 0.3 mm of drizzle is a completely different afternoon from forty percent chance of 12 mm. Pick a destination below to see both numbers hour by hour, plus the dry windows.
Each city page returns a direct verdict — go, carry a layer, or plan indoors — and shows a lead-time confidence band, so you know when the timing can still shift.
Probability and amount answer different questions
A 60% chance of 0.3 mm of drizzle and a 40% chance of 12 mm of rain describe completely different afternoons, yet most forecasts show only the percentage. Probability tells you how likely the model ensemble is to produce measurable rain at that hour; the amount tells you whether that rain changes your plans. Each destination page shows both, hour by hour, and highlights the dry windows between them.
Showers versus frontal rain
Convective showers are short, intense and poorly localised — the models know rain is likely somewhere in the area but not exactly where or when, so timing can shift by an hour or more. Frontal rain arrives on a predictable schedule and lasts. The city pages show a lead-time confidence band alongside the forecast, so you can tell when the timing is trustworthy and when the sensible plan is simply to stay flexible.

Frequently asked questions
Will it rain today?
Pick a destination below. Each page gives hour-by-hour rain probability and expected millimetres in local time, plus a direct verdict: go, carry a layer, or plan indoors.
What does a 40% chance of rain mean?
It means roughly 40% of the model ensemble members produce measurable rain at that location and hour. It says nothing about intensity or duration, which is why the expected amount matters just as much as the percentage.
How far ahead is a rain forecast reliable?
Rain timing is usually dependable one to three days out, broadly useful to about five days, and indicative only beyond seven. Each city page shows a lead-time confidence band so you can judge confidence rather than guess.
