Weather in August
Temperature
With its high average temperature of 94.6°F (34.8°C) and a low of 73.2°F (22.9°C), August is regarded as the warmest month.Heat index
For most parts of August, the heat index is appraised at a life-threatening hot 118.4°F (48°C). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.When assessing, remember that heat index measurements are for light winds and shaded spots. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
