Weather in July
Temperature
July, with average temperatures reaching a high of 87.4°F (30.8°C) and a low of 67.6°F (19.8°C), is the warmest month.Heat index
July's average heat index is calculated to be a fiery hot 102.2°F (39°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
