Weather in July
Temperature
July's climate shows a minor adjustment in average high-temperatures to a still hot 93.4°F (34.1°C) from June's 89.1°F (31.7°C). July's nights observe an average temperature of 74.5°F (23.6°C).Heat index
In July, the heat index is estimated at a life-threatening hot 113°F (45°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
