The month of August in Bahamas experiences essentially constant cloud cover, with the percentage of time that the sky is overcast or mostly cloudy remaining about 60% throughout the month.

The clearest day of the month is August 3, with clear, mostly clear, or partly cloudy conditions 42% of the time.

For reference, on June 13, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 68%, while on February 25, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 79%.

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Bahamas, the chance of a wet day over the course of August is rapidly increasing, starting the month at 13% and ending it at 19%.

For reference, the year's highest daily chance of a wet day is 30% on June 1, and its lowest chance is 6% on December 26.

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 August in Bahamas is gradually increasing, starting the month at 0.7 inches, when it rarely exceeds 1.8 inches, and ending the month at 1.1 inches, when it rarely exceeds 2.2 inches or falls below 0.2 inches.

Over the course of August in Bahamas, the length of the day is decreasing. From the start to the end of the month, the length of the day decreases by 38 minutes, implying an average daily decrease of 1 minute, 16 seconds, and weekly decrease of 8 minutes, 54 seconds.

The shortest day of the month is August 31, with 12 hours, 38 minutes of daylight and the longest day is August 1, with 13 hours, 17 minutes of daylight.

The earliest sunrise of the month in Bahamas is 6:37 AM on August 1 and the latest sunrise is 13 minutes later at 6:50 AM on August 31.

The latest sunset is 7:53 PM on August 1 and the earliest sunset is 25 minutes earlier at 7:28 PM on August 31.

Daylight saving time is observed in Bahamas during 2024, but it neither starts nor ends during August, so the entire month is in standard time.

For reference, on June 20, the longest day of the year, the Sun rises at 6:20 AM and sets 13 hours, 42 minutes later, at 8:02 PM, while on December 21, the shortest day of the year, it rises at 6:50 AM and sets 10 hours, 35 minutes later, at 5:25 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 August 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 Bahamas is essentially constant during August, remaining around 100% throughout.

For reference, on June 12, the muggiest day of the year, there are muggy conditions 100% of the time, while on February 19, the least muggy day of the year, there are muggy conditions 48% 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 Bahamas is gradually decreasing during August, decreasing from 12.8 miles per hour to 12.2 miles per hour over the course of the month.

For reference, on November 26, the windiest day of the year, the daily average wind speed is 15.2 miles per hour, while on September 18, the calmest day of the year, the daily average wind speed is 11.5 miles per hour.

The hourly average wind direction in Bahamas throughout August is predominantly from the east, with a peak proportion of 90% on August 1.

Bahamas 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 Bahamas is essentially constant during August, remaining around 85°F throughout.

The highest average surface water temperature during August is 85°F on August 28.

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 Bahamas 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 Bahamas are very rapidly increasing during August, increasing by 979°F, from 5,875°F to 6,854°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 Bahamas is essentially constant during August, remaining within 0.2 kWh of 5.2 kWh throughout.

For the purposes of this report, the geographical coordinates of Bahamas are 25.041 deg latitude, -77.371 deg longitude, and 0 ft elevation.

The topography within 2 miles of Bahamas is essentially flat, with a maximum elevation change of 0 feet and an average elevation above sea level of 0 feet. Within 10 miles is also essentially flat (0 feet). Within 50 miles is also essentially flat (0 feet).

The area within 2 miles of Bahamas is covered by grassland (60%), trees (19%), and shrubs (17%), within 10 miles by water (83%), and within 50 miles by water (93%).
