The number of hours during which the Sun is visible (black line), with various degrees of daylight, twilight, and night, indicated by the color bands. From bottom (most yellow) to top (most gray): full daylight, solar twilight (Sun is visible but less than 6° from the horizon), civil twilight (Sun is not visible but is less than 6° below the horizon), nautical twilight (Sun is between 6° and 12° below the horizon), astronomical twilight (Sun is between 12° and 18° below the horizon), and full night.

The earliest sunrise is at 6:52am on March 31 and the latest sunset is at 8:41pm on July 3. The latest sunrise is at 7:57am on October 27 and the earliest sunset is at 6:18pm on November 24.

Daylight saving time (DST) is observed in this location during 2012, starting in the spring on April 1 and ending in the fall on October 28.

Daily Sunrise & Sunset with Twilight and Daylight Saving Time

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. The transitions to and from daylight saving time are indicated by the "DST" labels.

The median cloud cover ranges from 21% (mostly clear) to 81% (mostly cloudy). The sky is cloudiest on July 18 and clearest on March 4. The clearer part of the year begins around October 17. The cloudier part of the year begins around June 8.

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 March 4, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 42% of the time, and overcast or mostly cloudy 12% of the time.

On July 18, the cloudiest day of the year, the sky is overcast, mostly cloudy, or partly cloudy 41% of the time, and clear or mostly clear 8% 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.

The probability that precipitation will be observed at this location varies throughout the year. Precipitation is most likely around September 7, occurring in 26% of days. Precipitation is least likely around March 19, occurring in 1% of days.

Probability of Precipitation at Some Point in the Day

dashboard

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 moderate rain, light rain, and drizzle.

Moderate rain is the most severe precipitation observed during 52% of those days with precipitation. It is most likely around September 5, when it is observed during 14% of all days.

Light rain is the most severe precipitation observed during 24% of those days with precipitation. It is most likely around September 9, when it is observed during 8% of all days.

Drizzle is the most severe precipitation observed during 15% of those days with precipitation. It is most likely around July 14, 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 June 14 to November 1, there is a 20% 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 (51% of days with precipitation have at worst moderate rain), light rain (25%), and drizzle (15%).

During the cold season, which lasts from January 22 to May 4, there is a 1% 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 (61% of days with precipitation have at worst moderate rain), light rain (19%), and drizzle (16%).

Warm Season Precipitation

Cold Season Precipitation

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

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.

The relative humidity typically ranges from 64% (mildly humid) to 91% (very humid) over the course of the year, rarely dropping below 53% (mildly humid) and reaching as high as 100% (very humid).

The air is driest around December 26, at which time the relative humidity drops below 70% (humid) three days out of four; it is most humid around September 9, exceeding 86% (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 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 60°F (comfortable) to 78°F (oppressive) and is rarely below 55°F (very comfortable) or above 80°F (very oppressive).

Over the course of the year typical wind speeds vary from 0 mph to 14 mph (calm to moderate breeze), rarely exceeding 25 mph (strong breeze).

The highest average wind speed of 7 mph (light breeze) occurs around June 27, at which time the average daily maximum wind speed is 14 mph (moderate breeze).

The lowest average wind speed of 5 mph (light breeze) occurs around November 9, at which time the average daily maximum wind speed is 11 mph (gentle breeze).

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.
