Climate overview

Temperature

Monthly mean temperatures are lowest in January, at -7.9 °C, and reach their highest monthly mean in July, at 15.6 °C. These are averages for each month rather than daytime maximum temperatures, so they describe the overall monthly temperature profile without indicating the range visitors might experience within a day. The unweighted mean across the calendar-month means is 3.0 °C. It summarizes the monthly averages equally rather than weighting them by the number of days in each month.

Snow

Mean daily snowfall is highest in December, at 17.56 mm/day. This is an average daily amount, not a monthly total; it does not establish how many days receive snow, snow depth or cover, or whether conditions suit skiing. The unweighted mean across the monthly snowfall averages is 8.60 mm/day per day. This broad summary does not specify when snowfall occurs beyond the monthly figures or describe conditions on a particular visit.

Rain

Mean daily rainfall is lowest in both January / December at 0.01 mm/day, while its highest monthly mean occurs in July at 1.57 mm/day. These are daily average amounts, not monthly totals, and the lower average does not guarantee rain-free days or indicate how often rain occurs. Across the calendar-month means, the unweighted mean daily rainfall is 0.52 mm/day. This offers an overall reference for average daily amounts but does not describe the timing or frequency of individual rainfall events.

Sunshine

Mean daily sunshine duration reaches its highest monthly average in June, at 13.31 hours/day, and its lowest in December, at 6.83 hours/day. Sunshine duration can help with broad outdoor-planning expectations, but it is not the same as daylight length and does not promise a particular day's conditions. The unweighted mean of the monthly sunshine averages is 10.14 hours/day per day, a calendar-wide summary rather than a prediction for any individual date.

Best Travel Time Guide for Crested Butte, USA: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, January / December is the data-based option to consider, with mean daily rainfall of 0.01 mm/day; this does not guarantee dry days or quantify rain frequency. Plan for rain if travelling in July, when the mean daily amount is 1.57 mm/day, and treat both figures as averages rather than forecasts. If cooler monthly mean temperatures are a priority, January has the lowest recorded monthly mean at -7.9 °C. This average is not a daytime high or a description of day-to-day variability, so use it as a broad planning reference rather than a guarantee of specific conditions.

For outdoor sightseeing planned around average sunshine duration, June has the highest monthly mean at 13.31 hours/day, while December has the lowest at 6.83 hours/day. Sunshine hours are not day length and cannot promise clear weather on a chosen date; these averages can inform planning, but not replace date-specific forecasts. The highest monthly mean daily snowfall occurs in December, at 17.56 mm/day. It is useful as a broad seasonal planning signal only: a daily mean does not tell you the number of snowy days, snow cover or depth, or whether skiing conditions will be present.
