May weather forecast
Parnaguá, Brazil

May, the last month of the autumn in Parnaguá, is another warm month, with temperature in the range of an average low of 18.8°C (65.8°F) and an average high of 29.9°C (85.8°F).

Temperature

May's weather displays an average high-temperature of a still moderately hot 29.9°C (85.8°F), slightly varied from April's 29.8°C (85.6°F). In May, the nighttime temperature lowers to an average of 18.8°C (65.8°F).

Heat index

May's average heat index is calculated to be a torrid 36°C (96.8°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

The average relative humidity in May is 74%.

Rainfall

In Parnaguá, in May, it is raining for 11 days, with typically 24mm (0.94") of accumulated precipitation. In Parnaguá, during the entire year, the rain falls for 134.3 days and collects up to 578mm (22.76") of precipitation.

Sunshine

In May, the average sunshine is 6.8h.

UV index

January through July, November and December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for the ordinary person.
Note: In May, the maximum UV index of 6 suggests these recommendations:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
