Weather in July
Temperature
July, on average, is the warmest month, registering a high temperature of 81.1°F (27.3°C) and a low of 63.1°F (17.3°C).Heat index
The heat index in July is calculated to be a tropical 86°F (30°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
