Climate Chart of Arapahoe Basin, USA

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

Climate overview

Temperature

Monthly mean temperature is lowest in January, at -14.4 °C, and reaches its highest monthly mean in July, at 7.5 °C. The unweighted mean of the monthly means is -4.6 °C. These are monthly averages, not daytime highs or a forecast of the conditions a visitor will encounter on a particular day; plan for variation within each month rather than treating the mean as a daily limit.

Snow

Mean daily snowfall is highest in April, at 17.22 mm/day, and lowest in July, at 0.34 mm/day. The unweighted mean across monthly means is 9.28 mm/day. These are average daily amounts, not monthly totals; they do not show how many days have snowfall or establish snow depth, snow cover, or skiing conditions.

Rain

Mean daily rainfall is highest in July, at 3.45 mm/day, and lowest in January, at 0.00 mm/day. The unweighted mean across monthly means is 0.76 mm/day. These are daily averages, not monthly rainfall totals, and the low monthly mean does not establish how often rain occurs or guarantee dry days. Use the figures as a broad guide, not a substitute for checking conditions close to travel.

Sunshine

Mean daily sunshine duration reaches its highest monthly mean in June, at 13.22 hours/day, and its lowest in December, at 7.32 hours/day. The unweighted mean across monthly means is 10.27 hours/day. These averages can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length and does not promise clear skies on any given day.

Best Travel Time Guide for Arapahoe Basin, USA: Ideal Seasons and Weather Insights

For visitors prioritising cooler monthly mean temperatures, January is the relevant month in these records, with a mean of -14.4 °C. Treat that as a monthly average rather than a guide to daytime highs or a guarantee about a particular visit, and check the forecast nearer your trip. If lower average daily rainfall is your priority, January is the conditional option, with a mean of 0.00 mm/day. Rain preparation is especially relevant for July, when the mean daily amount is 3.45 mm/day. Neither average tells you how frequently rain falls, so bring suitable layers and check current conditions rather than assuming either month will be consistently dry or wet. For daylight outdoor planning, mean daily sunshine is highest in June at 13.22 hours/day, and lowest in December at 7.32 hours/day. These averages describe sunshine duration, not day length or guaranteed sun; they are one planning consideration, not a single best-time ranking.

Snowfall records show the highest mean daily amount in April at 17.22 mm/day. This average alone cannot tell you the number of snowy days, snow depth, snow cover, or whether conditions suit a particular activity, so use it only as broad context and seek current local conditions when making plans.
