Weather in July
Temperature
August notes the warmest temperatures in July, with a high average of 94.3°F (34.6°C) and a low of 59.4°F (15.2°C).Heat index
In July, the heat index is estimated at a sweltering 100.4°F (38°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
