Heat index

During February, the heat index is computed to be a sweltering 38°C (100.4°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
When referencing the heat index, its values are suitable for shady environments and light breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Note: The UV index of 12 in February translates into these instructions:
Undertake all critical precautions. Protection from sun harm is vital. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Enhance your sun protection with tightly woven, yet airy clothing. Regularly apply and reapply a broad-spectrum sunscreen with a minimum SPF 30 every two hours, or straight after swimming or an outdoor activity. Caution! The mirror effect of sand and water ups the UV radiation strength.
