Weather in July
Temperature
Reva experiences its highest temperatures in July, with an average peak of 85.1°F (29.5°C) and a low of 63.5°F (17.5°C).Heat index
July's heat index is computed to be a tropical 86°F (30°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Realize that the values for the heat index are set for shaded places and light winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
