Weather in August
Temperature
As Harriston welcomes August, the average high-temperature stabilizes at a still tropical 91°F (32.8°C), showing little deviation from July's 91.4°F (33°C). The low-temperature average for Harriston during August stands at an agreeable 72.3°F (22.4°C).Heat index
Throughout August, the heat index is computed to be a blazing hot 113°F (45°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.The metrics for the heat index are tailored for both shady environments and light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', arises from combining readings of air temperature and relative moisture content. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Remember, however, that not all shade structures provide full sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
