While weather can vary considerably, information on weather conditions collected at the Pelly Ranch weather reporting station over the 1971-to-2000 period showed the average daytime temperature in January reached about minus 22 degrees Celsius, dropping to close to minus 33 degrees C overnight. In July the daytime temperature averaged over 22 degrees C, with overnight temperatures moving down to about 8 degrees C. Annual precipitation over the 30-year period totaled 310 millimetres, including 198 mm of rain and about 113 centimetres of snow.
Weather information has been recorded in the area since 1899. At first, weather information was gathered at Fort Selkirk and forwarded to Environment Canada; later, the reporting site was moved to the Pelly River Ranch. The ranch is about 45 km west of Pelly Crossing by road, in the same river valley as the community.
