Weather in July
Temperature
July is the warmest month, with the temperature often reaching an average high of 81.7°F (27.6°C) and an average low of 65.1°F (18.4°C).Heat index
July's average heat index is appraised at a tropical 89.6°F (32°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. 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. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
