Weather in July
Temperature
July tends to be the warmest month, with temperatures averaging a daily high of 81.9°F (27.7°C) and a low of 64.9°F (18.3°C).Heat index
In July, the average heat index is calculated to be a hot 89.6°F (32°C). Extended exposure and activity might lead to tiredness, potentially resulting in heat cramps.Know that the heat index computations account for shaded terrains and slight winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection.
