The numbers
| Daily high | 21°C |
|---|---|
| Nightly low | 13°C |
| Feels like, afternoon | 20°C |
| Rainy days, 1 mm or more | 10 · 80 mm |
| Humidity | 78% |
| Sunshine | 9.0 h/day |
| Daylight | 12.6 h/day |
| Crowds | 81 / 100, higher is quieter |
Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.
Weather read at the Mount: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.
