Weather in July
Temperature
The warmest time of the year is July, with temperatures averaging a high of 81.9°F (27.7°C) and a low of 63°F (17.2°C).Heat index
The heat index value for July is evaluated at a hot 87.8°F (31°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
