Weather in July
Temperature
The warmest period tends to be July, when average temperatures fluctuate between a high of 92.5°F (33.6°C) and a low of 58.1°F (14.5°C).Heat index
For July, the heat index is evaluated at a very hot 96.8°F (36°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
