Probability of Precipitation at Some Point in the Day in March

The fraction of days in which various types of precipitation are observed. If more than one type of precipitation is reported in a given day, the more severe precipitation is counted. For example, if light rain is observed in the same day as a thunderstorm, that day counts towards the thunderstorm totals. The order of severity is from the top down in this graph, with the most severe at the bottom.

Throughout March, the most common forms of precipitation are light rain, moderate rain, and thunderstorms.

Light rain is the most severe precipitation observed during 51% of those days with precipitation. It is most likely around March 1, when it is observed during 1% of all days.

Moderate rain is the most severe precipitation observed during 25% of those days with precipitation. It is most likely around March 1, when it is observed during 0% of all days.

Thunderstorms are the most severe precipitation observed during 16% of those days with precipitation. They are most likely around March 1, when it is observed during 0% of all days.

Dew Point

Dew point is often a better measure of how comfortable a person will find the weather than relative humidity because it more directly relates to whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid.

Over the course of a typical March, the dew point typically varies from 44°F (dry) to 66°F (muggy) and is rarely below 34°F (dry) or above 69°F (muggy).

The time of the month between March 1 and March 28 is the most comfortable, with dew points that are neither too dry nor too muggy.
