May weather forecast
Nova Russas, Brazil

The last month of the autumn, May, is another tropical month in Nova Russas, Brazil, with an average temperature varying between 20.4°C (68.7°F) and 30.3°C (86.5°F).

Temperature

April and May are characterised by lowest temperatures, with an average high of 30.3°C (86.5°F).

Heat index

In May, the average heat index is calculated to be a torrid 38°C (100.4°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
