Weather in July
Temperature
July is the warmest month, with an average high-temperature of 84.7°F (29.3°C) and an average low-temperature of 63.1°F (17.3°C).Heat index
The average heat index in July is calculated to be a hot 89.6°F (32°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
