Weather in August
Temperature
The transition into August marks the average high-temperature at a still tropical 88.3°F (31.3°C), differing minimally from July's 89.6°F (32°C). The temperature lowers to an average of 76.3°F (24.6°C) during August nights.Heat index
August's average heat index is estimated at a blisteringly hot 104°F (40°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
Humidity
The average relative humidity in August is 76%.Rainfall
August is the month with the most rainfall. Rain falls for 22.7 days and accumulates 4.29" (109mm) of precipitation.Snowfall

Sunshine
In August, the average sunshine is 10.7h.UV index
The months with the highest UV index are May through August, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for average individuals.Note: In August, a daily maximum UV index of 7 leads to the following instructions:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
