Weather in July
Temperature
The warmest period is July, when temperatures fluctuate between an average high of 81.1°F (27.3°C) and a low of 64.6°F (18.1°C).Heat index
July's mean heat index is computed to be a tropical 87.8°F (31°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.In reference to the heat index, it's for places in shade and with a slight wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
