Heat index

The heat index value for August is computed to be a blazing hot 113°F (45°C). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', quantifies the warmth felt when relative humidity is considered. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Note: In August, the UV index of 7 transforms into the following advice:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
