Cloud Cover Types

The fraction of time spent in each of the five sky cover categories. From top (most blue) to bottom (most gray), the categories are clear, mostly clear, partly cloudy, mostly cloudy, and overcast. Pink indicates missing data. Outside of the United States clear skies are often reported ambiguously, leading them to be lumped in with the missing data.

Precipitation

The probability that precipitation will be observed at this location varies throughout the year. Precipitation is most likely around July 30, occurring in 83% of days. Precipitation is least likely around December 23, occurring in 14% 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 thunderstorms, moderate rain, and light rain.

Thunderstorms are the most severe precipitation observed during 52% of those days with precipitation. They are most likely around July 29, when it is observed during 51% of all days.

Moderate rain is the most severe precipitation observed during 23% of those days with precipitation. It is most likely around June 22, when it is observed during 16% of all days.

Light rain is the most severe precipitation observed during 22% of those days with precipitation. It is most likely around September 10, when it is observed during 19% 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 March 24 to June 5, there is a 47% 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 thunderstorms (55% of days with precipitation have at worst thunderstorms), moderate rain (25%), and light rain (18%).

During the cold season, which lasts from December 6 to February 7, there is a 15% 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 moderate rain (36% of days with precipitation have at worst moderate rain), light rain (33%), thunderstorms (21%), and drizzle (9%).

Warm Season Precipitation

Cold Season Precipitation

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

Snow

Either snow is exceptionally unlikely to fall at any time during the year at this location or this station does not reliably report precipitation types.

Humidity

The relative humidity typically ranges from 24% (dry) to 97% (very humid) over the course of the year, rarely dropping below 11% (very dry) and reaching as high as 100% (very humid).

The air is driest around March 11, at which time the relative humidity drops below 31% (comfortable) three days out of four; it is most humid around September 2, exceeding 95% (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 26°F (dry) to 56°F (comfortable) and is rarely below 13°F (dry) or above 58°F (comfortable).

The time of the year between May 11 and November 8 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 16 mph (calm to moderate breeze), rarely exceeding 22 mph (fresh breeze).

The highest average wind speed of 5 mph (light breeze) occurs around April 11, at which time the average daily maximum wind speed is 16 mph (moderate breeze).

The lowest average wind speed of 3 mph (light air) occurs around December 21, at which time the average daily maximum wind speed is 13 mph (moderate 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 south west (3% of the time), north (3% of the time), west (4% of the time), and north west (5% 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.
