Climate Chart of Montpelier, USA

Climate overview

Temperature

The coolest monthly mean temperature occurs in January, at -7.0 °C; the warmest is in July, at 21.2 °C. These are monthly averages, not daytime highs, so they describe the broad temperature pattern rather than the range visitors might encounter from day to day. Across the calendar months, the unweighted mean of monthly mean temperatures is 7.5 °C. This summarizes the monthly figures without weighting them by the number of days in each month.

Rain

Mean daily rainfall is lowest in February, at 0.63 mm/day. For visitors prioritising lower average rainfall, that month is a conditional option, not a guarantee of dry weather or an indication of how often rain occurs. The highest monthly mean daily rainfall is in July, at 3.62 mm/day. It may be worth preparing for wet conditions when planning outdoor activities then; this daily mean is not a monthly rainfall total. The unweighted mean of the monthly daily rainfall means is 2.27 mm/day. It gives a summary across calendar months, but does not indicate the likelihood of rain on a particular travel day.

Snow

Mean daily snowfall is highest in February, at 12.82 mm/day. The unweighted mean across the monthly daily snowfall averages is 4.53 mm/day. These amounts do not establish how many days have snow, snow depth or snow cover, so they cannot determine conditions for winter activities.

Sunshine

Mean daily sunshine reaches its highest monthly value in July, at 11.28 hours/day, and its lowest in December, at 4.13 hours/day. These figures can help visitors prioritising sunshine when planning outdoor sightseeing, but sunshine duration is not the same as day length. The unweighted mean of monthly mean daily sunshine is 7.66 hours/day. It summarizes the monthly averages rather than promising a particular amount of sun on any given day.
