Temperature

As March takes its course, Médeyre's average high-temperature registers at a still warm 29.5°C (85.1°F), closely aligning with the preceding month. In the month of March, Médeyre witnesses a consistent average low-temperature of 22.8°C (73°F).

Heat index

The heat index for March is computed to be a sweltering 37°C (98.6°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

In Médeyre, the average relative humidity in March is 82%.

Note: The daily maximum UV index of 6 in March interprets into the following advice:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
