Rainfall in mm
Hi. When the rain is reported to be 70mm for example. What is the unit of time? Is that 70mm over an hour? A day?
Thanks in advance
Hi, First of all, Windy does not show reported rain but only forecast rain.
In the Rain layer, it’s clearly the quantity of rain during 3 hours.
In Meteogram, it is 3h too, or 1h if you are Premium user.
If you want to know the 24h rainfall forecast, see Rain accumulation.
