Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Bergen varies throughout the year.

The wetter season lasts 7.1 months, from August 18 to March 21, with a greater than 51% chance of a given day being a wet day. The chance of a wet day peaks at 64% on January 1.

The drier season lasts 4.9 months, from March 21 to August 18. The smallest chance of a wet day is 37% on May 2.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 60% on September 25.

Daily Chance of Precipitation

The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day).

Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Bergen experiences very significant seasonal variation in monthly rainfall.

Rain falls throughout the year in Bergen. The most rain falls during the 31 days centered around December 25, with an average total accumulation of 9.7 inches.

The least rain falls around May 12, with and average total accumulation of 3.8 inches.

Average Monthly Rainfall

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

Snowfall

We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day in the year. Bergen experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 5.4 months, from November 2 to April 15, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around February 5, with an average total liquid-equivalent accumulation of 1.0 inches.

The snowless period of the year lasts for 6.6 months, from April 15 to November 2. The least snow falls around July 20, with an average total liquid-equivalent accumulation of 0.0 inches.

Average Liquid-Equivalent Monthly Snowfall

The average liquid-equivalent snowfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average rainfall.

Humidity

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. 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 perceived humidity level in Bergen, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

Humidity Comfort Levels

The percentage of time spent at various humidity comfort levels, categorized by dew point: dry < 55°F < comfortable < 60°F < humid < 65°F < muggy < 70°F < oppressive < 75°F < miserable.

Wind

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Bergen experiences mildly seasonal variation over the course of the year.

The windier part of the year lasts for 5.9 months, from October 1 to March 28, with average wind speeds of more than 4.8 miles per hour. The windiest day of the year is January 7, with an average hourly wind speed of 6.1 miles per hour.

The calmer time of year lasts for 6.1 months, from March 28 to October 1. The calmest day of the year is July 12, with an average hourly wind speed of 3.5 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Bergen varies throughout the year.

The wind is most often from the north for 3.9 weeks, from June 3 to June 30, with a peak percentage of 36% on June 14. The wind is most often from the south for 11 months, from June 30 to June 3, with a peak percentage of 49% on February 26.

The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

Water Temperature

Bergen is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average water temperature experiences some seasonal variation over the course of the year.

The time of year with warmer water lasts for 2.6 months, from July 6 to September 25, with an average temperature above 56°F. The day of the year with the warmest water is August 11, with an average temperature of 59°F.

The time of year with cooler water lasts for 4.3 months, from December 26 to May 3, with an average temperature below 45°F. The day of the year with the coolest water is March 14, with an average temperature of 41°F.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences very significant seasonal variation over the course of the year.

The brighter period of the year lasts for 3.0 months, from May 5 to August 5, with an average daily incident shortwave energy per square meter above 4.6 kWh. The brightest day of the year is June 14, with an average of 5.8 kWh.

Data Sources

This report illustrates the typical weather in Bergen, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There is only a single weather station, Bergen / Flesland, in our network suitable to be used as a proxy for the historical temperature and dew point records of Bergen.

At a distance of 13 kilometers from Bergen, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.

The station records are corrected for the elevation difference between the station and Bergen according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . 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.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
