Weather in July
Temperature
July tends to be the warmest month, with temperatures averaging a daily high of 83.8°F (28.8°C) and a low of 67.8°F (19.9°C).Heat index
In July, the average heat index is computed to be a tropical 93.2°F (34°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Humidity
In July, the average relative humidity is 77%.Rainfall
The month with the most rainfall is July, when the rain falls for 18 days and typically aggregates up to 3.5" (89mm) of precipitation.Snowfall
June through October are months without snowfall.Daylight

Sunshine
The month with the most sunshine is July, with an average of 10.6h of sunshine.UV index
The months with the highest UV index are June through August, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the average person.Note: In July, the average maximum UV index of 6 translates into the following recommendations:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
