Climate Chart of Stevens Pass, USA

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperatures reach their high at August with 18.2 °C, while the low comes in December at -3.2 °C. These are averages for each month, not daytime highs or lows, so they describe the broad seasonal contrast rather than the full range visitors may encounter. The unweighted mean of the monthly mean temperatures is 6.4 °C; it summarizes the calendar-month averages without giving extra weight to longer months.

Rain

Mean daily rainfall is highest in October at 3.40 mm/day and lowest in July at 0.34 mm/day. These are daily averages, not monthly accumulation totals, and the lower figure does not mean every day is dry or indicate how often rain occurs. Across the monthly means, the unweighted mean daily rainfall is 1.48 mm/day. This is a summary of the month-level daily averages, not a day-weighted annual figure.

Sunshine

Sunshine duration averages are longest in July, at 13.63 hours/day per day, and shortest in December, at 3.65 hours/day per day. Sunshine duration is not the same as day length, and monthly averages cannot promise clear skies on a particular visit.

Snow

Mean daily snowfall reaches its highest monthly average in January at 33.26 mm/day. This is a daily mean rather than a monthly total; the available fact identifies the peak month, not the snowfall expected on any particular day.

Best Travel Time Guide for Stevens Pass, USA: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, July is the conditional option: mean daily rainfall is 0.34 mm/day. It is not a guarantee of dry days or a measure of rain frequency, so retain flexible plans and rain protection. If choosing for cooler monthly mean conditions, consider December, when the monthly mean is -3.2 °C; this does not describe daytime maximum temperatures or the range on individual days. For rain preparation, note the higher mean daily rainfall in October at 3.40 mm/day, and pack suitable layers and waterproof gear rather than assuming conditions will match the average.

Outdoor sightseeing planned around sunshine averages may favor July, with 13.63 hours/day of mean daily sunshine, while December has 3.65 hours/day. These figures describe sunshine duration, not daylight length or guaranteed sun, so check conditions close to travel and avoid treating either month as a universal best time to visit.
