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 Melville is essentially constant during July, remaining within 1% of 4% throughout.
The highest chance of a muggy day during July is 4% on July 19.
For reference, on July 19, the muggiest day of the year, there are muggy conditions 4% 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 Melville is gradually decreasing during July, decreasing from 10.0 miles per hour to 9.4 miles per hour over the course of the month.
For reference, on March 30, the windiest day of the year, the daily average wind speed is 12.2 miles per hour, while on July 30, 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 30.
Average Wind Speed in July
The hourly average wind direction in Melville throughout July is predominantly from the west, with a peak proportion of 36% on July 17.

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 Melville typically lasts for 4.1 months (126 days), from around May 16 to around September 19, rarely starting before April 29 or after June 2, and rarely ending before August 31 or after October 6.
The month of July in Melville 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 Melville are increasing during July, increasing by 433°F, from 559°F to 993°F, over the course of the month.

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 in Melville is essentially constant during July, remaining within 0.2 kWh of 6.7 kWh throughout.
The highest average daily incident shortwave solar energy during July is 6.9 kWh on July 15.

This report illustrates the typical weather in Melville 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 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Melville.
For each station, the records are corrected for the elevation difference between that station and Melville 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 Melville is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Melville and a given station.
The stations contributing to this reconstruction are: Yorkton Municipal Airport (43%, 45 kilometers, northeast); Broadview, Sask. (27%, 63 kilometers, south); Indian Head (22%, 72 kilometers, southwest); and Wynyard Marine Aviation Reporting Station (8%, 136 kilometers, northwest).
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.
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.
