For most parts of August, the heat index is appraised at a tropical 93.2°F (34°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees.
