For reference, the year's highest daily chance of a wet day is 27% on August 1, and its lowest chance is 2% on February 21.
Probability of Precipitation in January
To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day rainfall during January in Hércules is essentially constant, remaining about 0.3 inches throughout, and rarely exceeding 1.1 inches.
The highest average 31-day accumulation is 0.3 inches on January 11.
Average Monthly Rainfall in January
Over the course of January in Hércules, the length of the day is gradually increasing. From the start to the end of the month, the length of the day increases by 27 minutes, implying an average daily increase of 55 seconds, and weekly increase of 6 minutes, 22 seconds.
The shortest day of the month is January 1, with 10 hours, 24 minutes of daylight and the longest day is January 31, with 10 hours, 51 minutes of daylight.
Hours of Daylight and Twilight in January
The latest sunrise of the month in Hércules is 7:48 AM on January 11 and the earliest sunrise is 5 minutes earlier at 7:43 AM on January 31.
The earliest sunset is 6:10 PM on January 1 and the latest sunset is 24 minutes later at 6:34 PM on January 31.
Daylight saving time is observed in Hércules during 2020, but it neither starts nor ends during January, so the entire month is in standard time.
For reference, on June 20, the longest day of the year, the Sun rises at 6:59 AM and sets 13 hours, 55 minutes later, at 8:54 PM, while on December 21, the shortest day of the year, it rises at 7:42 AM and sets 10 hours, 22 minutes later, at 6:04 PM.
Sunrise & Sunset with Twilight in January
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 chance that a given day will be muggy in Hércules is essentially constant during January, remaining around 0% throughout.
For reference, on June 24, the muggiest day of the year, there are muggy conditions 1% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% 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 Hércules is essentially constant during January, remaining within 0.2 miles per hour of 8.6 miles per hour throughout.
For reference, on April 9, the windiest day of the year, the daily average wind speed is 10.1 miles per hour, while on October 9, the calmest day of the year, the daily average wind speed is 7.8 miles per hour.
Average Wind Speed in January
The hourly average wind direction in Hércules throughout January is predominantly from the west, with a peak proportion of 37% on January 31.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
The growing season in Hércules typically lasts for 9.4 months (287 days), from around February 16 to around November 29, rarely starting before January 20 or after March 17, and rarely ending before November 10 or after December 15.
The month of January in Hércules is more likely than not fully outside of the growing season, with the chance that a given day is in the growing season rapidly increasing from 1% to 24% over the course of the month.
Time Spent in Various Temperature Bands and the Growing Season in January
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Hércules are gradually increasing during January, increasing by 133°F, from 0°F to 133°F, over the course of the month.

This report illustrates the typical weather in Hércules year round, 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 is only a single weather station, Presidio Lely International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Hércules.
At a distance of 186 kilometers from Hércules, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .
The weight assigned to the MERRA-2 value depends on the distance from Hércules to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 42%, making the weight assigned to the weather station 58%.
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.
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.
Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. 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.
We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
