Climate Chart of Richmond, USA

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

Climate overview

Temperature

The monthly mean temperature is coolest in January, at 10.0 °C, and reaches its highest monthly mean in September, at 18.9 °C. These figures describe average temperatures across each month, not typical afternoon highs, so they are best used as broad context when considering what conditions to expect. The unweighted mean across the monthly temperature averages is 14.7 °C. It summarizes the supplied monthly means without weighting them by the number of days in each month.

Rain

Mean daily rainfall is highest in December, at 3.67 mm/day, and lowest in August, at 0.01 mm/day. The figures are daily averages associated with each month, not monthly rainfall totals; the lower average does not guarantee rain-free days or reveal how often rain occurs. The unweighted mean of the monthly daily-rainfall averages is 1.42 mm/day. For planning, it provides an overall reference while leaving day-to-day rainfall variable.

Sunshine

Mean daily sunshine reaches its highest monthly average in June, at 13.07 hours/day, and its lowest in December, at 6.20 hours/day. These durations can help with broad outdoor scheduling, but sunshine hours are not the same as day length. The unweighted mean across the monthly sunshine averages is 10.01 hours/day per day. It is a summary of those monthly means, not a promise of sunshine on a particular day.

Snow

Mean daily snowfall reaches its highest monthly average in February, at 0.02 mm/day. This small recorded daily mean does not establish how many days receive snow, whether snow accumulates or persists, or whether conditions support skiing.

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

Visitors prioritising lower average rainfall can consider August, when mean daily rainfall is 0.01 mm/day; this is a conditional choice based on the average, not a guarantee of dry weather or a measure of rain frequency. For rain preparation, note that the highest monthly mean daily rainfall is in December at 3.67 mm/day, and plan for the possibility of wet days. Those seeking cooler monthly average conditions may focus on January, the coolest month by mean temperature at 10.0 °C. This monthly mean does not describe daytime highs or the full range of conditions within the month, so use it as a general guide rather than a precise forecast.

For outdoor sightseeing planned around average sunshine duration, June has the highest mean daily sunshine at 13.07 hours/day, while December has the lowest at 6.20 hours/day. These averages may inform broad daylight planning, but sunshine duration is not day length and does not guarantee clear skies on travel dates. The highest monthly mean daily snowfall is recorded in February at 0.02 mm/day. That average alone cannot indicate snowy-day frequency, snow depth or cover, or skiing conditions, so it should not be used as a stand-alone basis for snow-dependent plans.
