Heat index

The heat index in March is appraised at a blistering 42°C (107.6°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
One should consider that heat index numbers are for shaded settings and light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Note: The maximum UV index, 12 during March, leads to the following recommendations:
Take every vital safeguard, as unprotected skin and eyes may suffer burns rapidly. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. Even on overcast days, ensure the application and frequent reapplication of sunscreen with at least an SPF 30, especially post swim or outdoor exercise. Be attentive! The UV exposure is heightened with reflections from sand and water.
