Weather in July
Temperature
The average temperatures reach their apex in July, averaging 81.1°F (27.3°C) at the high end and 64.9°F (18.3°C) at the low end.Heat index
July's mean heat index is estimated at a tropical 87.8°F (31°C). Extended exposure and activity might lead to tiredness, potentially resulting in heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
