Weather in July
Temperature
Temperature records mark July as the warmest month, with highs averaging 81.5°F (27.5°C) and lows at 63.3°F (17.4°C).Heat index
The average heat index in July is computed to be a tropical 87.8°F (31°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
