Precipitation

The average probability that some form of precipitation will be observed in a given day is 47%, with little variation over the course of the month.

Probability of Precipitation at Some Point in the Day in October

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

Thunderstorms are the most severe precipitation observed during 47% of those days with precipitation. They are most likely around October 1, when it is observed during 28% of all days.

Light rain is the most severe precipitation observed during 37% of those days with precipitation. It is most likely around October 29, when it is observed during 21% of all days.

Moderate rain is the most severe precipitation observed during 15% of those days with precipitation. It is most likely around October 31, when it is observed during 9% of all days.

Types of Precipitation Throughout October

Relative frequency of various types of precipitation over the course of a typical October.

Snow

Either snow is exceptionally unlikely to fall at this location in October or this station does not reliably report precipitation types.

Humidity

The relative humidity typically ranges from 57% (mildly humid) to 96% (very humid) over the course of a typical October, rarely dropping below 41% (comfortable) and reaching as high as 100% (very humid).

The air is driest around October 5, at which time the relative humidity drops below 64% (mildly humid) three days out of four; it is most humid around October 26, rising above 94% (very humid) three days out of four.

Relative Humidity in October

The average daily high (blue) and low (brown) relative humidity with percentile bands (inner bands from 25th to 75th percentile, outer bands from 10th to 90th percentile).

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 October, the dew point typically varies from 44°F (dry) to 62°F (mildy humid) and is rarely below 36°F (dry) or above 67°F (muggy).

The time of the month between October 1 and October 31 is the most comfortable, with dew points that are neither too dry nor too muggy.

Dew Point in October

Wind Directions in October

The fraction of time spent with the wind blowing from the various directions over the entire year. Values do not sum to 100% because the wind direction is undefined when the wind speed is zero.

Fraction of Time Spent with Various Wind Directions in October

The fraction of time spent with the wind blowing from the various directions on a daily basis. Stacked values do not always sum to 100% because the wind direction is undefined when the wind speed is zero.
