Heat index

In February, the average heat index is estimated at a very hot 35°C (95°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. 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 primarily vital for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
