Weather in July
Temperature
The warmest time of the year is July, with temperatures averaging a high of 89.2°F (31.8°C) and a low of 68.7°F (20.4°C).Heat index
The heat index value during July is calculated to be an extremely hot 105.8°F (41°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
