Weather in July
Temperature
July, having an average high-temperature of 87.4°F (30.8°C) and an average low-temperature of 70°F (21.1°C), is the warmest month.Heat index
July's mean heat index is estimated at a very hot 98.6°F (37°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. 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', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
