Geography and Climate

Geography

Mount Lorne is located in the Yukon Southern Lakes; broad valleys and large lakes characterize this ecoregion. Set within the rain shadow of the Coast Mountains, this ecoregion’s climate is dry and cool. The Yukon Southern Lakes Ecoregion lies in the sporadic discontinuous permafrost zone, where permafrost underlies less than one-quarter of the landscape.

The ecoregion supports the highest diversity of mammals in the Yukon, with at least 50 of the 60 species known to occur in the Yukon at present.

Climate

Mount Lorne is less than 50 kilometers from Whitehorse; while no independent climate information is available for the smaller communities, climate information for Whitehorse gives a fairly good indication of general weather conditions. Localized anomalies in some of the valley areas can occur.

Over the past few decades, the daily temperature in January in Whitehorse reached daytime highs of minus 13 Celsius, dropping to minus 22 Celsius overnight.

 In July the daily temperatures typically reach a high of 20 Celsius and a low at night of about 8 Celsius.

Whitehorse has a relatively dry climate; annual precipitation over several decades averaged close to 270 mm, including 160 to 165 mm of rain and 145 cm of snow.
