Weather in July
Temperature
The warmest period tends to be July, when average temperatures fluctuate between a high of 82°F (27.8°C) and a low of 70.5°F (21.4°C).Heat index
In July, the average heat index is calculated to be a tropical 87.8°F (31°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
