Weather in August

August, the last month of the summer in Topside, is another tropical month, with an average temperature varying between 64.4°F (18°C) and 86.7°F (30.4°C).

Temperature

The start of August sees the average high-temperature at a still hot 86.7°F (30.4°C), showing little difference from July's 87.6°F (30.9°C). Topside, after an intense day, registers a significant cooling to an average low-temperature of 64.4°F (18°C) throughout August.

Heat index

August's heat index is calculated to be a very hot 98.6°F (37°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
