Weather in July
Temperature

For most parts of July, the heat index is appraised at a sweltering 95°F (35°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
