However, the city does witness a slight decrease in daylight hours to 13.1, indicating the elongating shadows of an approaching autumn. Frequent showers continue, accompanied by the highest average relative humidity of the year at 77%. Wind speed sees a marginal increase, providing periods of cooler relief from the persistent heat.

Temperature

Orlando witnesses the warmest weather in August, with temperatures averaging a high of 91°F (32.8°C) and a low of 76.8°F (24.9°C).

Heat index

The average heat index in August is computed to be a life-threatening hot 114.8°F (46°C). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. 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 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Always opt for UVA and UVB-resistant sunglasses on radiant days.
