Temperature

July is Cypress's warmest month, registering average high temperatures of 88°F (31.1°C) and lows of 68.5°F (20.3°C).

Heat index

The heat index in July is appraised at an extremely hot 104°F (40°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
