Weather in July
Temperature
July, with its average high-temperature of 82°F (27.8°C) and an average low-temperature of 65.7°F (18.7°C), holds the record as the warmest month.Heat index
During July, the heat index is computed to be a tropical 89.6°F (32°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
