A wet day is one with at least 0. To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding day period centered around each day. The average sliding day rainfall during January in San Jose is essentially constant , remaining about 3.

Over the course of January in San Jose, the length of the day is increasing. From the start to the end of the month, the length of the day increases by 41 minutes , implying an average daily increase of 1 minute, 22 seconds , and weekly increase of 9 minutes, 34 seconds. The shortest day of the month is January 1 , with 9 hours, 39 minutes of daylight and the longest day is January 31 , with 10 hours, 20 minutes of daylight.

Daylight saving time is observed in San Jose during , but it neither starts nor ends during January, so the entire month is in standard time. For reference, on June 21 , the longest day of the year, the Sun rises at AM and sets 14 hours, 44 minutes later, at PM , while on December 21 , the shortest day of the year, it rises at AM and sets 9 hours, 35 minutes later, at PM.

The figure below presents a compact representation of key lunar data for January The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon.

The vertical gray bars new Moons and blue bars full Moons indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.

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. 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 San Jose is essentially constant during January, remaining within 0. For reference, on June 6 , the windiest day of the year, the daily average wind speed is 8. The lowest daily average wind speed during January is 6. San Jose is located near a large body of water e.

This section reports on the wide-area average surface temperature of that water. While it does not do so every year, freezing temperatures are seen in San Jose over some winters. 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. 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 in San Jose is gradually increasing during January, rising by 0. For the purposes of this report, the geographical coordinates of San Jose are The topography within 2 miles of San Jose is essentially flat , with a maximum elevation change of 82 feet and an average elevation above sea level of 86 feet.

Within 10 miles is essentially flat 2, feet. Within 50 miles contains large variations in elevation 4, feet. This report illustrates the typical weather in San Jose, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in San Jose.

For each station, the records are corrected for the elevation difference between that station and San Jose 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 San Jose is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between San Jose and a given station.

The stations contributing to this reconstruction are: Norman Y. To get a sense of how much these sources agree with each other, you can view a comparison of San Jose and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.

All data relating to the Sun's position e. 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 kilometer grid.
