September weather forecast
Malta, Brazil

September, the first month of the spring in Malta, is still a hot month, with an average temperature ranging between max 32.8°C (91°F) and min 20.3°C (68.5°F).

Temperature

September denotes a minimal variation in the average high-temperature to a still hot 32.8°C (91°F) from August's 31.7°C (89.1°F). Malta observes a substantial disparity between daytime high and the average low-temperature of 20.3°C (68.5°F) during September nights.

Heat index

During September, the heat index is calculated to be a very hot 38°C (100.4°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

The average relative humidity in September is 56%.

Rainfall

The months with the least rainfall are August and September Rain falls for 1.2 days and accumulates 1mm (0.04") of rain.

Sunshine

With an average of 9.9h of sunshine, September has the most sunshine of the year in Malta.

UV index

The months with the highest UV index in Malta are January through March, August through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for average individuals.
Note: An average maximum UV index of 7 in September leads to these recommendations:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
