Weather in July
Temperature
July, marked by an average high-temperature of 82.9°F (28.3°C) and a low-temperature of 49.1°F (9.5°C), is the warmest month.Heat index
The heat index value for July is calculated to be 84.2°F (29°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.

For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
