Average Monthly Rainfall in July
Due to its extreme latitude, Gjoa Haven 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 Gjoa Haven during 2018, the Sun is continuously above the horizon for 2.0 months, rising at 12:47 AM on May 22, and not setting again until 12:12 AM on July 21. 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, 12 minutes of daylight.

Sunrise & Sunset with Twilight in July
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 Gjoa Haven is essentially constant during July, remaining around 0% throughout.
For reference, on July 26, 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 Gjoa Haven is essentially constant during July, remaining within 0.3 miles per hour of 9.7 miles per hour throughout.
For reference, on October 6, the windiest day of the year, the daily average wind speed is 12.9 miles per hour, while on July 12, the calmest day of the year, the daily average wind speed is 9.4 miles per hour.
The lowest daily average wind speed during July is 9.4 miles per hour on July 12.

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 Gjoa Haven typically lasts for 2.1 months (63 days), from around June 23 to around August 25, rarely starting before June 8 or after July 12, and rarely ending before August 4 or after September 11.
The month of July in Gjoa Haven is more likely than not fully within the growing season, with the chance that a given day is in the growing season reaching a high of 93% on July 22.
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 Gjoa Haven are gradually increasing during July, increasing by 59°F, from 14°F to 74°F, over the course of the month.

Temperature and Dew Point
There is only a single weather station, Gjoa Haven Climate, in our network suitable to be used as a proxy for the historical temperature and dew point records of Gjoa Haven.
At a distance of 1 kilometer from Gjoa Haven, 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 Gjoa Haven 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.
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.
Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .

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.
