Weather in August
Temperature
August proves to be the warmest month, recording an average peak temperature of 93.9°F (34.4°C) and a minimum temperature of 72.5°F (22.5°C).Heat index
For August, the heat index is calculated to be a burning hot 120.2°F (49°C). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.Consider that heat index readings are for situations in the shade and light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
