Weather in July
Temperature
July, known for its average high temperature of 84.2°F (29°C) and an average low temperature of 66.7°F (19.3°C), is the warmest month.Heat index
The average heat index in July is computed to be a fiery hot 95°F (35°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
