Rainfall

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 November in Houston is decreasing, starting the month at 4.4 inches, when it rarely exceeds 9.6 inches or falls below 0.8 inches, and ending the month at 3.7 inches, when it rarely exceeds 6.6 inches or falls below 1.2 inches.

Over the course of November in Houston, the length of the day is decreasing. From the start to the end of the month, the length of the day decreases by 36 minutes, implying an average daily decrease of 1 minute, 14 seconds, and weekly decrease of 8 minutes, 40 seconds.

The shortest day of the month is November 30, with 10 hours, 23 minutes of daylight and the longest day is November 1, with 10 hours, 59 minutes of daylight.

The latest sunrise of the month in Houston is 7:36 AM on November 2 and the earliest sunrise is 59 minutes earlier at 6:37 AM on November 3.

The latest sunset is 6:34 PM on November 1 and the earliest sunset is 1 hour, 12 minutes earlier at 5:21 PM on November 30.

Daylight saving time (DST) starts at 1:00 AM on November 3, 2024, shifting sunrise and sunset to be an hour later.

For reference, on June 20, the longest day of the year, the Sun rises at 6:21 AM and sets 14 hours, 4 minutes later, at 8:25 PM, while on December 21, the shortest day of the year, it rises at 7:12 AM and sets 10 hours, 14 minutes later, at 5:26 PM.

The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation.

The figure below presents a compact representation of key lunar data for November 2024. 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.

The chance that a given day will be muggy in Houston is rapidly decreasing during November, falling from 29% to 16% over the course of the month.

For reference, on July 20, the muggiest day of the year, there are muggy conditions 98% of the time, while on January 29, the least muggy day of the year, there are muggy conditions 6% 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 Houston is essentially constant during November, remaining within 0.2 miles per hour of 8.5 miles per hour throughout.

For reference, on April 2, the windiest day of the year, the daily average wind speed is 9.4 miles per hour, while on August 15, the calmest day of the year, the daily average wind speed is 6.2 miles per hour.

The hourly average wind direction in Houston throughout November is predominantly from the south, with a peak proportion of 35% on November 11.

Houston is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average surface water temperature in Houston is decreasing during November, falling by 7°F, from 73°F to 66°F, over the course of the month.

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 Houston typically lasts for 12 months (351 days), from around January 18 to around January 3, rarely starting after February 26, or ending before December 4.

The month of November in Houston is very likely fully within the growing season, with the chance that a given day is in the growing season gradually decreasing from 100% to 94% over the course of the month.

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 Houston are increasing during November, increasing by 403°F, from 6,851°F to 7,254°F, over the course of the month.

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 Houston is gradually decreasing during November, falling by 0.9 kWh, from 4.1 kWh to 3.2 kWh, over the course of the month.
