Daily Sunrise & Sunset with Twilight

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 67% (partly cloudy) to 84% (mostly cloudy). The sky is cloudiest on January 22 and clearest on April 20. The clearer part of the year begins around March 6. The cloudier part of the year begins around May 28.

Median Cloud Cover

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 April 20, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 45% of the time, and overcast or mostly cloudy 41% of the time.

On January 22, the cloudiest day of the year, the sky is overcast, mostly cloudy, or partly cloudy 79% of the time, and clear or mostly clear 6% 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 February 9, occurring in 43% of days. Precipitation is least likely around September 28, occurring in 3% 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 63% of those days with precipitation. It is most likely around February 11, when it is observed during 26% of all days.

Moderate rain is the most severe precipitation observed during 17% of those days with precipitation. It is most likely around February 8, when it is observed during 12% of all days.

Drizzle is the most severe precipitation observed during 13% of those days with precipitation. It is most likely around June 18, when it is observed during 4% 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 February 21 to May 21, there is a 25% 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 (68% of days with precipitation have at worst light rain), moderate rain (16%), thunderstorms (8%), and drizzle (6%).

During the cold season, which lasts from August 16 to November 10, there is a 4% 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 (53% of days with precipitation have at worst light rain) and drizzle (42%).

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 58% (mildly humid) to 95% (very humid) over the course of the year, rarely dropping below 48% (comfortable) and reaching as high as 100% (very humid).

The air is driest around December 18, at which time the relative humidity drops below 64% (mildly humid) three days out of four; it is most humid around March 10, exceeding 92% (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 64°F (mildy humid) to 75°F (very muggy) and is rarely below 61°F (comfortable) or above 77°F (oppressive).

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 72 mph (violent storm).

The highest average wind speed of 10 mph (gentle breeze) occurs around November 26, at which time the average daily maximum wind speed is 16 mph (moderate breeze).

The lowest average wind speed of 5 mph (light breeze) occurs around February 6, at which time the average daily maximum wind speed is 11 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 south (32% of the time), south west (21% of the time), and west (13% of the time). The wind is least often out of the north east (1% of the time), north (1% of the time), east (2% of the time), and south east (3% 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.
