Weather in August
Temperature
Hazelwood records an average high-temperature of a moderately hot 85.5°F (29.7°C) in August, closely mirroring the climate of the previous month. Throughout the month of August, Hazelwood observes an average nighttime temperature of 67.1°F (19.5°C).Heat index
August's average heat index is computed to be a sweltering 95°F (35°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
