Sunrise & Sunset with Twilight and Daylight Saving Time
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.
Orlando experiences extreme seasonal variation in the perceived humidity.
The muggier period of the year lasts for 6.7 months, from April 24 to November 16, during which time the comfort level is muggy, oppressive, or miserable at least 30% of the time. The muggiest day of the year is July 31, with muggy conditions 100% of the time.
The least muggy day of the year is January 30, with muggy conditions 7% 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 Orlando experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 8.1 months, from September 29 to June 3, with average wind speeds of more than 4.0 miles per hour. The windiest day of the year is March 10, with an average hourly wind speed of 5.1 miles per hour.
The calmer time of year lasts for 3.9 months, from June 3 to September 29. The calmest day of the year is August 4, with an average hourly wind speed of 3.0 miles per hour.

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 significant seasonal variation over the course of the year.
The brighter period of the year lasts for 2.1 months, from April 2 to June 6, with an average daily incident shortwave energy per square meter above 6.1 kWh. The brightest day of the year is May 2, with an average of 6.8 kWh.

This report illustrates the typical weather in Orlando, 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 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Orlando.
For each station, the records are corrected for the elevation difference between that station and Orlando 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 Orlando is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Orlando and a given station.
The stations contributing to this reconstruction are: Executive Airport (81%, 4.6 kilometers, east); Orlando International Airport (17%, 13 kilometers, southeast); and Leesburg International Airport (2.1%, 53 kilometers, northwest).
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.
