Weather in August
Temperature
Ohlman experiences a transition to a still moderately hot 81.9°F (27.7°C) in average high-temperatures with the arrival of August, not greatly differing from July's 83.1°F (28.4°C). An average low-temperature of 64.9°F (18.3°C) is noted during the month of August.Heat index
For most parts of August, the heat index is appraised at a tropical 87.8°F (31°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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.
