A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Santa Ana varies significantly throughout the year.
The wetter season lasts 7.3 months, from April 18 to November 27, with a greater than 25% chance of a given day being a wet day. The chance of a wet day peaks at 46% on October 22.
The drier season lasts 4.7 months, from November 27 to April 18. The smallest chance of a wet day is 3% on January 20.
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 46% on October 22.
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 of the year. Santa Ana experiences significant seasonal variation in 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.
Santa Ana experiences some seasonal variation in the perceived humidity.
The muggier period of the year lasts for 10 months, from March 13 to January 20, during which time the comfort level is muggy, oppressive, or miserable at least 84% of the time. The muggiest day of the year is October 25, with muggy conditions 100% of the time.
The least muggy day of the year is February 9, with muggy conditions 79% 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 Santa Ana does not vary significantly over the course of the year, remaining within 0.3 miles per hour of 1.2 miles per hour throughout.
Average Wind Speed
The predominant average hourly wind direction in Santa Ana varies throughout the year.
The wind is most often from the west for 2.7 months, from March 28 to June 20 and for 4.8 months, from July 14 to December 9, with a peak percentage of 64% on October 4. The wind is most often from the east for 3.4 weeks, from June 20 to July 14 and for 3.6 months, from December 9 to March 28, with a peak percentage of 37% on July 8.
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 2.8 months, from January 9 to April 4, with an average daily incident shortwave energy per square meter above 5.7 kWh. The brightest day of the year is March 1, with an average of 6.2 kWh.
The darker period of the year lasts for 2.8 months, from August 30 to November 23, with an average daily incident shortwave energy per square meter below 4.2 kWh. The darkest day of the year is October 4, with an average of 3.7 kWh.

Temperature and Dew Point
There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Santa Ana.
For each station, the records are corrected for the elevation difference between that station and Santa Ana 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 Santa Ana is computed as the weighted average of the individual contributions from each station, in addition to a contribution from the MERRA-2 reconstruction, corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Santa Ana.
The station weigths are proportional to the inverse of the distance between Santa Ana and a given station.
The weight assigned to the MERRA-2 value depends on the distance from Santa Ana to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 20%.
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.
