Weather in July
Temperature
July, with average temperatures reaching a high of 83.1°F (28.4°C) and a low of 61.2°F (16.2°C), is the warmest month.Heat index
The heat index for July is estimated at a tropical 91.4°F (33°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
