Weather in May

May, the last month of the autumn in Matemba, is also a hot month, with an average temperature fluctuating between 30°C (86°F) and 21.6°C (70.9°F).

Temperature

The average high-temperature in May, at a still hot 30°C (86°F), reveals a modest deviation from April's 30.4°C (86.7°F). In the month of May, Matemba witnesses a consistent average low-temperature of 21.6°C (70.9°F).

Heat index

In May, the average heat index is estimated at a blistering 40°C (104°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Note that heat index values are valued for light wind and location in the shade. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

In May, the average relative humidity is 88%.

Rainfall

UV index

The months with the highest UV index in Matemba are January through September, with an average maximum UV index of 6. A UV Index of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for ordinary individuals.
Note: A daily maximum UV index of 6 in May translates into the following instructions:
Shield from overexposure. Defense against sun-related harm is required. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
