The clearer part of the year in Quito begins around May 25 and lasts for 4.1 months, ending around September 29. On July 31, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 49% of the time, and overcast or mostly cloudy 51% of the time.
The cloudier part of the year begins around September 29 and lasts for 7.9 months, ending around May 25. On March 14, the cloudiest day of the year, the sky is overcast or mostly cloudy 91% of the time, and clear, mostly clear, or partly cloudy 9% of the time.
A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Quito varies very significantly throughout the year.
The wetter season lasts 5.5 months, from December 11 to May 27, with a greater than 44% chance of a given day being a wet day. The chance of a wet day peaks at 76% on April 18.
The drier season lasts 6.5 months, from May 27 to December 11. The smallest chance of a wet day is 11% on July 31.
Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 76% on April 18.
Daily Chance of Precipitation
To 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 in the year. Quito experiences very significant seasonal variation in monthly rainfall.
Rain falls throughout the year in Quito. The most rain falls during the 31 days centered around April 10, with an average total accumulation of 6.4 inches.
The least rain falls around August 7, with and average total accumulation of 0.5 inches.
Average Monthly Rainfall
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 perceived humidity level in Quito, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.
Humidity Comfort Levels
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 Quito experiences mildly seasonal variation over the course of the year.
The windier part of the year lasts for 3.1 months, from June 9 to September 13, with average wind speeds of more than 2.2 miles per hour. The windiest day of the year is August 1, with an average hourly wind speed of 3.0 miles per hour.
The calmer time of year lasts for 8.9 months, from September 13 to June 9. The calmest day of the year is April 18, with an average hourly wind speed of 1.6 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Quito varies throughout the year.
The wind is most often from the east for 9.1 months, from January 22 to October 24, with a peak percentage of 95% on July 31. The wind is most often from the west for 2.9 months, from October 24 to January 22, with a peak percentage of 46% on November 22.
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 experiences some seasonal variation over the course of the year.
The brighter period of the year lasts for 1.8 months, from July 28 to September 23, with an average daily incident shortwave energy per square meter above 5.8 kWh. The brightest day of the year is August 24, with an average of 6.1 kWh.
The darker period of the year lasts for 7.1 months, from October 26 to May 29, with an average daily incident shortwave energy per square meter below 5.1 kWh. The darkest day of the year is December 14, with an average of 4.8 kWh.

Temperature and Dew Point
There is only a single weather station, Mariscal Sucre International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Quito.
At a distance of 11 kilometers from Quito, 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 Quito 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.
