the land was turned over to the rearing of cattle. Climate Trevelin has a cool summer humid climate (Köppen Cfb), but with a rainfall pattern similar to the Mediterranean climate. The climate is milder than that of other locations on the Argentine side of Northern Patagonia because of the low altitude and the direct exposure to Pacific winds. This microclimate allows for intensive agriculture, a rarity in the region where mid-summer frosts occur every year. Nighttime temperatures rarely drop below and although snowfall is frequent, it does not cover the ground for long periods of time. Winters are stormy with frequent rain, sleet and snow while summers are cool, windy and relatively dry. Mean annual precipitation is . The precipitation pattern resembles a Mediterranean one, where most (75%) of the precipitation is concentrated from April to August, the cooler months with a dry period from September to March. Snowfall can occur during the colder months while rainfall predominates in warmer months; hail rarely occurs. The mean temperature in Trevelin ranges from in July, the coldest month to in January, the warmest month. Frosts can occur at any time, even in summer, which limits the range of agricultural activities.
