Weather in July
Temperature

The heat index value during July is estimated at a torrid 96.8°F (36°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.For clarity, heat index numbers account for light winds and areas under shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
