The average sliding 31-day rainfall during July in Svolvær is essentially constant, remaining about 2.4 inches throughout, and rarely exceeding 4.7 inches or falling below 0.7 inches.
Average Monthly Rainfall in July
Due to its extreme latitude, Svolvær experiences polar day (also known as the midnight Sun) during the summer and polar night during the winter. These are periods of time in which the sun is continuously above or below the horizon for more than one day. The precise start and end dates of polar day and night vary from year to year and depend on the precise location and elevation of the observer, and the local topography.
In the summer in Svolvær during 2019, the Sun is continuously above the horizon for 1.8 months, rising at 1:17 AM on May 25, and not setting again until 12:38 AM on July 20. As such, July begins the month in polar day, which ends before the month is out.
The shortest day of the month is July 31, with 20 hours, 2 minutes of daylight.
Hours of Daylight and Twilight in July
The earliest sunrise of the month in Svolvær is 1:37 AM on July 20 and the latest sunrise is 1 hour, 27 minutes later at 3:04 AM on July 31.

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 chance that a given day will be muggy in Svolvær is essentially constant during July, remaining around 0% throughout.
For reference, on July 28, the muggiest day of the year, there are muggy conditions 0% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.

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 Svolvær is gradually decreasing during July, decreasing from 8.9 miles per hour to 8.2 miles per hour over the course of the month.
For reference, on January 23, the windiest day of the year, the daily average wind speed is 15.6 miles per hour, while on July 29, the calmest day of the year, the daily average wind speed is 8.2 miles per hour.
The lowest daily average wind speed during July is 8.2 miles per hour on July 30.

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).
The growing season in Svolvær typically lasts for 5.4 months (165 days), from around May 5 to around October 16, rarely starting before April 14 or after May 25, and rarely ending before September 25 or after November 11.
The month of July in Svolvær is reliably fully within the growing season.
Time Spent in Various Temperature Bands and the Growing Season in July
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. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Svolvær are gradually increasing during July, increasing by 156°F, from 108°F to 264°F, over the course of the month.

This report illustrates the typical weather in Svolvær year round, 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 are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Svolvær.
For each station, the records are corrected for the elevation difference between that station and Svolvær according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Svolvær is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Svolvær and a given station.
The stations contributing to this reconstruction are: Svolvær Airport, Helle (98%, 4.4 kilometers, northeast); Værøy Heliport (0.9%, 101 kilometers, southwest); and Bodø Airport (0.8%, 108 kilometers, south).
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.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.
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.
