Weather in July
Temperature
The average temperatures reach their apex in July, averaging 85.5°F (29.7°C) at the high end and 68°F (20°C) at the low end.Heat index
During July, the heat index is estimated at a torrid 95°F (35°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
