Precipitation

The probability that precipitation will be observed at this location varies throughout the year. Precipitation is most likely around December 14, occurring in 70% of days. Precipitation is least likely around August 4, occurring in 38% of days.

Probability of Precipitation at Some Point in the Day

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.

Over the entire year, the most common forms of precipitation are light rain, moderate rain, and drizzle.

Light rain is the most severe precipitation observed during 48% of those days with precipitation. It is most likely around April 8, when it is observed during 33% of all days.

Moderate rain is the most severe precipitation observed during 27% of those days with precipitation. It is most likely around January 21, when it is observed during 22% of all days.

Drizzle is the most severe precipitation observed during 10% of those days with precipitation. It is most likely around July 31, when it is observed during 14% of all days.

Types of Precipitation Throughout the Year

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

During the warm season, which lasts from June 22 to September 24, there is a 41% average chance that precipitation will be observed at some point during a given day. When precipitation does occur it is most often in the form of light rain (47% of days with precipitation have at worst light rain), drizzle (29%), and moderate rain (19%).

During the cold season, which lasts from November 15 to March 13, there is a 67% average chance that precipitation will be observed at some point during a given day. When precipitation does occur it is most often in the form of light rain (46% of days with precipitation have at worst light rain), moderate rain (30%), heavy rain (8%), and light snow (7%).

Warm Season Precipitation

Cold Season Precipitation

Relative frequency of various types of precipitation during the warm and cold seasons respectively.

Snow

The likelihood of snow falling is highest around January 18, occurring in 8% of days.

Probability of Snow Fall Being Reported in a Given Day

Probability that snow will be reported at least once in a given day. The season is defined as the period during which the probability is greater than one third the maximum probability.

Either snow rarely accumulates at this location or snow depth measurements are unavailable or unreliable.

Humidity

The relative humidity typically ranges from 64% (mildly humid) to 100% (very humid) over the course of the year, rarely dropping below 45% (comfortable) and reaching as high as 100% (very humid).

The air is driest around May 14, at which time the relative humidity drops below 72% (humid) three days out of four; it is most humid around August 25, exceeding 100% (very humid) three days out of four.

Relative Humidity

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 year, the dew point typically varies from 33°F (dry) to 57°F (comfortable) and is rarely below 24°F (dry) or above 60°F (comfortable).

The time of the year between May 25 and October 18 is the most comfortable, with dew points that are neither too dry nor too muggy.

Dew Point

The daily average low (blue) and high (red) dew point with percentile bands (inner band from 25th to 75th percentile, outer band from 10th to 90th percentile).

Wind

Over the course of the year typical wind speeds vary from 0 mph to 14 mph (calm to moderate breeze), rarely exceeding 22 mph (fresh breeze).

The highest average wind speed of 7 mph (light breeze) occurs around March 30, at which time the average daily maximum wind speed is 13 mph (moderate breeze).

The lowest average wind speed of 4 mph (light breeze) occurs around October 9, at which time the average daily maximum wind speed is 9 mph (gentle breeze).

Wind Speed

The average daily minimum (red), maximum (green), and average (black) wind speed with percentile bands (inner band from 25th to 75th percentile, outer band from 10th to 90th percentile).
The wind direction is highly variable and is not predominantly from any single direction.The wind is least often out of the north (2% of the time), north east (2% of the time), and south west (4% of the time).

Wind Directions Over the Entire Year

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

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.
