Measured at the BERG weather station, 13.7 km away at 350 m; the village itself is at 222 m. ^[11]

The village sits 128 m below the station, so each day's reading was shifted by 5.89 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. ^[11]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[11]

Humidity measured at BERG, 13.7 km away at 350 m, over 21 summers. ^[11]

That station sits 128 m above the village, so each day's humidity was shifted by 3.63 °C per km before the muggy days were counted. ^[11]

An average of 917 mm of rain a year, spread over 135 days — about 6.8 mm on a day it rains. ^[11]

Rainfall measured at SARREWERDEN, 6.9 km away at 235 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
