This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Petersburg. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. The rainless period of the year lasts for 4.5 months, from November 28 to April 11. The shaded overlays indicate night and civil twilight. Valley Brook annual snowfall: 74 inch Global Temperatures. The calmest day of the year is July 17, with an average hourly wind speed of 4.3 miles per hour. Time zones for airports and weather stations are provided by AskGeo.com . The cold season lasts for 4.0 months, from November 5 to March 4, with an average daily high temperature below 32°F. Rain falls throughout the year in Petersburg. The coldest day of the year is December 31, with an average low of 27°F and high of 35°F. We report snowfall in liquid-equivalent terms. Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies. For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The thin dotted lines are the corresponding average perceived temperatures. Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). Alaska had its warmest year on record in 2019 with average temperatures 6.2°F above the long-term average and most parts of the country saw above-average temperatures, according to … The snowless period of the year lasts for 6.5 months, from April 4 to October 20. Chickasha The hottest day of the year is July 19, with an average high of 68°F and low of 55°F. The shaded overlays indicate night and civil twilight. Spring comes to populated regions relatively late. The percentage of time spent at various humidity comfort levels, categorized by dew point. From bottom (most yellow) to top (most gray), the color bands indicate: full daylight, twilight (civil, nautical, and astronomical), and full night. Guthrie The darkest day of the year is December 19, with an average of 0.3 kWh. Edmond The thin dotted lines are the corresponding average perceived temperatures. The estimated value at Anchorage is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Anchorage and a given station. The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader. The length of the day in Petersburg varies extremely over the course of the year. This is awaited time of warmth after half of a year of cold winter. The average temperature in the contiguous United States reached 52.68 degrees Fahrenheit (11.49 degrees Celsius) in 2019. The Alaska Peninsula lies further to the south, so it has a milder winter, but the summer is still cold, so the vegetation is still tundra, that is, made of mosses and lichens. The daily average water temperature (purple line), with 25th to 75th and 10th to 90th percentile bands. The transitions to and from daylight saving time are indicated by the 'DST' labels. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. Anchorage experiences some seasonal variation in monthly liquid-equivalent snowfall. The percentage of time spent in various temperature bands. Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database . Cold Bay In Cold Bay, the average temperature is -2.5 °C (27.5 °F) in February and 11 °C (51.5 °F) in August. The coldest day of the year is January 17, with an average low of 13°F and high of 23°F. Cushing Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night. The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. The day of the year with the warmest water is August 13, with an average temperature of 55°F. All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , by Jean Meeus. The cloudier part of the year begins around April 20 and lasts for 9.8 months, ending around February 14. The least snow falls around July 20, with an average total liquid-equivalent accumulation of 0.0 inches.
