Weather in August
Temperature
Celina marks the onset of August with an average high-temperature of a still tropical 86.5°F (30.3°C), a subtle shift from July's 87.6°F (30.9°C). Compared to daytime temperatures, Celina's temperature drops significantly, averaging a refreshing 64.9°F (18.3°C) during the nights of August.Heat index
August's mean heat index is computed to be a very hot 98.6°F (37°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 remain especially vital for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
