Weather in July
Temperature
July, with its average high-temperature of 82.9°F (28.3°C) and an average low-temperature of 63°F (17.2°C), holds the record as the warmest month.Heat index
The heat index value during July is calculated to be a tropical 89.6°F (32°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
