Weather in July
Temperature
The transition into July reveals an average high-temperature of a still tropical 94.8°F (34.9°C), mirroring a close resemblance to June. July nights in Castle Hills observe an average temperature dip to a warm 74.3°F (23.5°C).Heat index
July's average heat index is calculated to be a life-threatening hot 116.6°F (47°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
