The solar day over the course of the year 2012 . From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (solar, civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray.

Clouds

The median cloud cover ranges from 59% (partly cloudy) to 88% (mostly cloudy). The sky is cloudiest on March 14 and clearest on July 17. The clearer part of the year begins around May 30. The cloudier part of the year begins around October 2.

The median daily cloud cover (black line) with percentile bands (inner band from 40th to 60th percentile, outer band from 25th to 75th percentile).

On July 17, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 58% of the time, and overcast or mostly cloudy 40% of the time.

On March 14, the cloudiest day of the year, the sky is overcast, mostly cloudy, or partly cloudy 85% of the time, and clear or mostly clear 5% of the time.

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 April 9, occurring in 73% of days. Precipitation is least likely around August 15, occurring in 29% 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 thunderstorms.

Light rain is the most severe precipitation observed during 32% of those days with precipitation. It is most likely around June 10, when it is observed during 23% of all days.

Moderate rain is the most severe precipitation observed during 30% of those days with precipitation. It is most likely around March 14, when it is observed during 23% of all days.

Thunderstorms are the most severe precipitation observed during 30% of those days with precipitation. They are most likely around April 12, when it is observed during 32% 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 September 13 to October 6, there is a 43% 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 (44% of days with precipitation have at worst thunderstorms), light rain (28%), and moderate rain (22%).

During the cold season, which lasts from February 7 to March 5, there is a 49% 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 (40% of days with precipitation have at worst moderate rain), light rain (28%), thunderstorms (22%), and heavy rain (6%).

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 35% (comfortable) to 98% (very humid) over the course of the year, rarely dropping below 27% (dry) and reaching as high as 100% (very humid).

The air is driest around August 10, at which time the relative humidity drops below 39% (comfortable) three days out of four; it is most humid around December 19, exceeding 96% (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 37°F (dry) to 54°F (very comfortable) and is rarely below 32°F (dry) or above 56°F (comfortable).

There are two periods in the year that are most comfortable: The first is between January 1 and June 23 and the second is between September 25 and December 31. The air feels neither too dry nor too muggy during these periods.

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 15 mph (calm to moderate breeze), rarely exceeding 23 mph (fresh breeze).

The highest average wind speed of 6 mph (light breeze) occurs around August 3, 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 April 15, at which time the average daily maximum wind speed is 12 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 is most often out of the north west (19% of the time), north (18% of the time), east (14% of the time), and south east (12% of the time). The wind is least often out of the south west (1% of the time) and west (2% 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.
