Weather in August
Temperature
An average high-temperature of a tropical 30.4°C (86.7°F) marks August, exhibiting a close resemblance to the conditions in July. During the month of August, the nighttime temperature in Loulouïe, French Guiana, falls to an average of 24.5°C (76.1°F).Heat index
August's heat index is estimated at a sweltering 38°C (100.4°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
