Very Light · average intensity
The rain is illustrative. Actual intensity varies within a storm.
The quick answer
0.5 mm/hrAverage rainfall rate- Total water per m²
- 1 litres
- Depth in inches
- 0.039 in
- Across a 100 m² area
- 100 litres
Volumes assume no runoff, evaporation or infiltration.
Amount and intensity are different.
1 mm tells you the total rain. Dividing that amount by 2 hours gives the average hourly rate of 0.5 mm/hr.
This falls in the explorer’s “very light” display category. Brief peaks could be higher, and weather services may use different category thresholds.

Soil, slopes, drainage, earlier rain and the shape of the storm all matter. A rainfall total alone cannot tell you whether a place will flood or whether travel is safe.
For conditions where you are, check official local forecasts and warnings. Use this page to understand the quantities.
