Follow the year at one representative 141.57 m coordinate
At the representative 141.57 m Kampeters Kolk coordinate, monthly mean temperature climbs from 0.51 °C in January to 18.11 °C in July. April is the driest average month at 1.57 mm of precipitation per day, whereas December reaches 2.55 mm/day and 93.79% humidity; daylight expands from 7.60 hours in December to 16.39 in June. These NASA POWER values summarize 1991–2020 climatology for one sampled point, not live reserve weather.
