Weather in August
Temperature
August's presence marks an average high-temperature of a still warm 81.9°F (27.7°C), subtly varied from July's 83.3°F (28.5°C). In the month of August, Houston witnesses a marked temperature drop at night, averaging a low of 59.9°F (15.5°C).Heat index
August's average heat index is estimated at a hot 87.8°F (31°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
