Based on this score, the best time of year to visit Calgary for general outdoor tourist activities is from early July to mid August, with a peak score in the third week of July. 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. Days with less than 20% cloud cover are considered as sunny, with 20-80% cloud cover as partly cloudy and with more than 80% as overcast. The horizontal axis is the day of the year, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. The cold season lasts for 3.7 months, from November 16 to March 7, with an average daily high temperature below 38°F. Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter. Based on growing degree days alone, the first spring blooms in Calgary should appear around May 6, only rarely appearing before April 22 or after May 19. The figure below presents a compact representation of key lunar data for 2020. 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. The climate profile is taken from closest available data source to Calgary. For October expect the sun to shine for an average of 7 hours per day.

Wind … The shaded overlays indicate night and civil twilight. The calmest day of the year is August 2, with an average hourly wind speed of 5.8 miles per hour. 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 . The Westreville, South Dakota Tornado rounds out the list with 230 mph winds (370 km/h). To maintain relevance to current weather trends the displayed information has been calculated using data collected over the past two decades. For Ottawa in January the daily average maximum temperatures is 0°C with the average minimum -9°C, while in June the average maximum is 26°C with a minimum of 13°C. The rainy period of the year lasts for 6.1 months, from April 9 to October 12, with a sliding 31-day rainfall of at least 0.5 inches. In 2014 we started to calculate weather models with historical data from 1985 onwards and generated a continuous 30-year global history with hourly weather data. The brighter period of the year lasts for 3.7 months, from April 29 to August 19, with an average daily incident shortwave energy per square meter above 5.6 kWh. The figure below shows you a compact characterization of the entire year of hourly average temperatures. This represents the average number of hours in the daytime that the sun is visible and not obscured by cloud e.g. The climate in Canada is typically varies from temperate in south to subarctic and arctic in north. Note we calculate hours of sunshine per day using our past forecast data, not observation data, thus it is an estimate and not actual. Lower dew points feel drier and higher dew points feel more humid. The predominant average hourly wind direction in Calgary is from the west throughout the year. The estimated value at Calgary is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Calgary and a given station. The thin dotted line is the corresponding average rainfall. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. The time in which the moon is above the horizon (light blue area), with new moons (dark gray lines) and full moons (blue lines) indicated. 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. Wind speed units can be changed in the preferences (top right). 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. Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory. The last 2 weeks of past weather data for Calgary are available for free evaluation here. Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more. The precipitation chart is useful to plan for seasonal effects such as monsoon climate in India or wet season in Africa. The stations contributing to this reconstruction are: Calgary International, Alta. 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. The simulated weather data have a spatial resolution of approximately 30 km and may not reproduce all local weather effects, such as thunderstorms, local winds, or tornadoes. The darkest day of the year is December 23, with an average of 1.0 kWh. The graph shows the monthly number of sunny, partly cloudy, overcast and precipitation days. The chance of a wet day peaks at 34% on June 16. This data can be used under the Creative Commons license "Attribution + Non-commercial (BY-NC)". Click on each chart for more information. The calmer time of year lasts for 5.0 months, from May 20 to October 18. For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. To characterize how pleasant the weather is in Calgary throughout the year, we compute two travel scores. The length of the day in Calgary varies extremely over the course of the year. The thin dotted lines are the corresponding average perceived temperatures. Based on this score, the best time of year to visit Calgary for hot-weather activities is from mid July to mid August, with a peak score in the last week of July. The average growing degree days accumulated over the course of the year, with 25th to 75th and 10th to 90th percentile bands. Monthly precipitations above 150mm are mostly wet, below 30mm mostly dry. The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. The thin dotted line is the corresponding average liquid-equivalent snowfall. Throughout the month you can expect to see rain or drizzle falling on 7 days of the month, with snow falling on 7 days. Time zones for airports and weather stations are provided by AskGeo.com . The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed. The average hourly wind speed in Calgary experiences mild seasonal variation over the course of the year. The coldest day of the year is January 1, with an average low of 12°F and high of 29°F.
