The winter in Bahrain experiences essentially constant cloud cover, with the percentage of time that the sky is overcast or mostly cloudy remaining about 26% throughout the season.

The clearest day of the winter is February 1, with clear, mostly clear, or partly cloudy conditions 78% of the time.

For reference, on August 10, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 45%, while on September 30, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 94%.

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Bahrain, the chance of a wet day over the course of the winter is essentially constant, remaining around 5% throughout.

For reference, the year's highest daily chance of a wet day is 7% on March 13, and its lowest chance is 0% on July 3.

Rainfall

To show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day.

The average sliding 31-day rainfall during the winter in Bahrain is essentially constant, remaining about 0.4 inches throughout, and rarely exceeding 1.6 inches or falling below -0.0 inches.

The highest average 31-day accumulation is 0.5 inches on January 19.

Over the course of the winter in Bahrain, the length of the day is increasing. From the start to the end of the season, the length of the day increases by 59 minutes, implying an average daily increase of 40 seconds, and weekly increase of 4 minutes, 38 seconds.

The shortest day of the winter is December 21, with 10 hours, 31 minutes of daylight and the longest day is February 28, with 11 hours, 37 minutes of daylight.

The latest sunrise of the winter in Bahrain is 6:26 AM on January 12 and the earliest sunrise is 25 minutes earlier at 6:02 AM on February 28.

The earliest sunset is 4:45 PM on December 1 and the latest sunset is 53 minutes later at 5:38 PM on February 28.

Daylight saving time is not observed in Bahrain during 2024.

For reference, on June 20, the longest day of the year, the Sun rises at 4:46 AM and sets 13 hours, 46 minutes later, at 6:32 PM, while on December 21, the shortest day of the year, it rises at 6:20 AM and sets 10 hours, 31 minutes later, at 4:51 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 the winter of 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 Bahrain is rapidly decreasing during the winter, falling from 22% to 3% over the course of the season.

The lowest chance of a muggy day during the winter is 1% on January 29.

For reference, on August 19, 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 1% 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 Bahrain is essentially constant during the winter, remaining within 0.6 miles per hour of 11.9 miles per hour throughout.

For reference, on February 8, the windiest day of the year, the daily average wind speed is 12.4 miles per hour, while on September 12, the calmest day of the year, the daily average wind speed is 8.4 miles per hour.

The highest daily average wind speed during the winter is 12.4 miles per hour on February 11.

The hourly average wind direction in Bahrain throughout the winter is predominantly from the north, with a peak proportion of 59% on February 13.

Bahrain 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 Bahrain is rapidly decreasing during the winter, falling by 9°F, from 75°F to 66°F, over the course of the season.

The lowest average surface water temperature during the winter is 65°F on February 10.

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).

Temperatures in Bahrain are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.

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 Bahrain are very rapidly decreasing during the winter, decreasing by 8,741°F, from 9,540°F to 799°F, over the course of the season.

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 Bahrain is increasing during the winter, rising by 1.4 kWh, from 3.9 kWh to 5.2 kWh, over the course of the season.

The lowest average daily incident shortwave solar energy during the winter is 3.7 kWh on December 27.
