Climate Chart of Annapolis, USA

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

Climate overview

Temperature

Monthly mean temperatures are lowest in January at 2.1 °C, and reach their highest in July at 25.6 °C. These are averages for each month, not daytime high temperatures, so individual days may differ. The unweighted mean across the monthly means is 14.0 °C; it gives a broad annual reference rather than a day-weighted average.

Rain

Mean daily rainfall is lowest in January at 2.16 mm/day and highest in July at 5.74 mm/day. These are daily averages for the respective months, not monthly accumulation totals, and they do not indicate how often rain falls or guarantee dry days. The unweighted mean of the monthly daily averages is 3.78 mm/day, useful as an overall reference but not a description of any particular day's weather.

Sunshine

Average daily sunshine reaches its highest level in July at 11.45 hours/day, while its lowest monthly mean is in December at 5.51 hours/day. The unweighted mean across the monthly sunshine averages is 8.48 hours/day. These figures describe sunshine duration, not daylight length, and monthly averages cannot show how sunny any individual day will be.

Snow

The highest monthly mean daily snowfall is recorded in January at 4.38 mm/day. The unweighted mean of the monthly daily snowfall averages is 1.05 mm/day. These amounts do not establish how many days have snow, how deep it becomes, whether snow cover develops, or whether conditions are suitable for skiing.

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

For visitors prioritising cooler monthly averages, January is the relevant reference point, with a mean temperature of 2.1 °C; this is not a prediction of daytime highs or a guarantee about conditions during a visit. Those focused on lower average rainfall can consider January, when mean daily rainfall is 2.16 mm/day, while keeping in mind that the average does not promise dry days or quantify rain frequency. Rain preparation is especially relevant when considering July, whose mean daily rainfall is 5.74 mm/day; the figure is not a monthly total, so it cannot describe the timing of showers on a particular day. For outdoor sightseeing planned around sunshine duration, July has the highest monthly mean at 11.45 hours/day, while December has the lowest at 5.51 hours/day. Sunshine hours are not day length, and neither average guarantees what visitors will experience.

If snowfall matters to your plans, the highest monthly mean daily amount is in January at 4.38 mm/day. This average cannot tell you how many snowy days to expect or establish snow depth, cover, or skiing conditions, so it should not be used alone to plan snow-dependent activities.
