Climate overview
Temperature
The warmest monthly mean temperature occurs in July at 15.8 °C. At the cooler end, December has the lowest monthly mean, -12.6 °C. These are monthly averages, not daytime maximum or minimum temperatures, so they describe the broad temperature pattern rather than the range visitors may encounter within a day. Across the calendar-month means, the unweighted mean is 0.8 °C. It summarizes the monthly averages without weighting them by the number of days in each month, and should not be read as a typical temperature for every visit or as a daily condition.
Rain
Mean daily rainfall is highest in July at 2.00 mm/day. This identifies the month with the greatest average daily amount in the supplied data; it does not imply rain every day or describe the timing of individual showers. The lowest mean daily rainfall is shared by February / November, at 0.01 mm/day. Visitors prioritising lower average rainfall could consider these months as conditional options, while remembering that a low mean does not guarantee dry days or indicate how often rain occurs. The unweighted mean across monthly means is 0.71 mm/day, not a day-weighted annual average or a monthly total.
Sunshine
Mean daily sunshine duration peaks in June at 13.33 hours/day, a useful reference for planning outdoor time around average sunshine. The lowest mean daily duration is in December at 1.66 hours/day. These figures measure sunshine duration, not day length, and do not guarantee the conditions on a particular date. The unweighted mean of the monthly sunshine means is 7.82 hours/day per day. It offers a broad summary across calendar months, rather than a day-weighted annual figure or a forecast for any individual visit.
Snow
Mean daily snowfall reaches its highest monthly mean in December at 7.75 mm/day. This is a daily average amount, not a monthly snowfall total; it cannot establish how many days have snow, snow depth or snow cover. The unweighted mean across the monthly means is 3.74 mm/day per day, which likewise does not indicate skiing conditions.
Best Travel Time Guide for Whitehorse, Canada: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly averages, December is the relevant option: its lowest monthly mean temperature is -12.6 °C. Treat that as a monthly average, not a prediction of daytime highs or conditions on a specific date, and plan clothing with that limitation in mind. If lower average rainfall is a priority, February / November is the conditional choice in these data, with a lowest mean daily rainfall of 0.01 mm/day. This does not guarantee dry weather or quantify rain frequency; for rain preparation, note that the highest mean daily rainfall is in July at 2.00 mm/day.
For daylight outdoor planning, average sunshine is greatest in June at 13.33 hours/day per day, while the lowest mean daily sunshine is in December at 1.66 hours/day. Sunshine duration is not day length and cannot promise clear conditions, so keep plans flexible rather than treating either average as a daily forecast. Snowfall averages peak in December at 7.75 mm/day per day. This mean does not show the number of snowy days, snow depth or snow cover, so it is not enough on its own to assess snow-dependent activities; check conditions closer to travel.
