RainfallTo 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 of the year. Rawdon experiences significant seasonal variation in monthly rainfall. The rainy period of the year lasts for 9.9 months, from February 27 to December 25, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around June 25, with an average total accumulation of 3.1 inches. The rainless period of the year lasts for 2.1 months, from December 25 to February 27. The least rain falls around January 29, with an average total accumulation of 0.4 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.
SnowfallWe 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 of the year. Rawdon experiences significant seasonal variation in monthly liquid-equivalent snowfall. The snowy period of the year lasts for 6.8 months, from October 14 to May 7, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around December 21, with an average total liquid-equivalent accumulation of 2.0 inches. The snowless period of the year lasts for 5.2 months, from May 7 to October 14. The least snow falls around July 26, 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.
SunThe length of the day in Rawdon varies significantly over the course of the year. In 2017, the shortest day is December 21, with 8 hours, 38 minutes of daylight; the longest day is June 21, with 15 hours, 46 minutes of daylight. Hours of Daylight and Twilight
The number of hours during which the Sun is visible (black line). From bottom (most yellow) to top (most gray), the color bands indicate: full daylight, twilight (civil, nautical, and astronomical), and full night.
The earliest sunrise is at 5:03 AM on June 15, and the latest sunrise is 2 hours, 37 minutes later at 7:40 AM on November 4. The earliest sunset is at 4:09 PM on December 10, and the latest sunset is 4 hours, 41 minutes later at 8:50 PM on June 25.

Sunrise & Sunset with Twilight and Daylight Saving Time
The solar day over the course of the year 2017. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The transitions to and from daylight saving time are indicated by the 'DST' labels.
HumidityWe 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. Rawdon experiences some seasonal variation in the perceived humidity. The muggier period of the year lasts for 3.2 months, from June 10 to September 15, during which time the comfort level is muggy, oppressive, or miserable at least 3% of the time. The muggiest day of the year is July 20, with muggy conditions 12% of the time. The least muggy day of the year is November 30, when muggy conditions are essentially unheard of. 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.
WindThis 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 Rawdon experiences mild seasonal variation over the course of the year. The windier part of the year lasts for 5.6 months, from November 20 to May 8, with average wind speeds of more than 3.7 miles per hour. The windiest day of the year is February 23, with an average hourly wind speed of 4.5 miles per hour. The calmer time of year lasts for 6.4 months, from May 8 to November 20. The calmest day of the year is July 31, with an average hourly wind speed of 2.8 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 Rawdon is from the west throughout the year. Wind Direction
The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions (north, east, south, and west), excluding hours in which the mean wind speed is less than 1 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).
Solar EnergyThis 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 extreme seasonal variation over the course of the year. The brighter period of the year lasts for 3.7 months, from May 3 to August 24, with an average daily incident shortwave energy per square meter above 5.5 kWh. The brightest day of the year is July 2, with an average of 6.6 kWh. The darker period of the year lasts for 3.4 months, from October 26 to February 10, with an average daily incident shortwave energy per square meter below 2.3 kWh. The darkest day of the year is December 17, with an average of 1.2 kWh. Average Daily Incident Shortwave Solar Energy

Data SourcesThis report illustrates the typical weather in Rawdon, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointThere are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Rawdon. For each station, the records are corrected for the elevation difference between that station and Rawdon 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 Rawdon is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Rawdon and a given station. The stations contributing to this reconstruction are: L'Assomption (38%, 35 kilometers, southeast); Montréal–Mirabel International Airport (27%, 48 kilometers, southwest); Lac Saint- Pierre (17%, 63 kilometers, east); and St Jovite Automatic Weather Reporting System (18%, 64 kilometers, west). Other DataAll 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.
