Weather in August

August ushers in the waning phase of summer, with temperatures dipping ever so slightly from the peaks of July. It’s noticeable, even if minor, that the month's rainfall is lower than July's, at 1.26" (32mm) on average. In addition to the warm temperature, August days retain extensive sunlight hours, though they are beginning to shorten. August remains as an inviting month for outdoor pursuits without the intensity of July's heat. As summer draws to a close, September is marked by a noticeable drop in temperatures and daylight hours.

Temperature

The transition from July to August sees average high-temperatures adjusting to a moderately hot 84.9°F (29.4°C), from a not significantly different 86.4°F (30.2°C). The temperature notes a substantial fall from the daily peak to an average of 61.5°F (16.4°C) during August nights.

Heat index

August's average heat index is calculated to be a very hot 95°F (35°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
