May weather forecast
Pebas, Peru

The last month of the autumn, May, is also a hot month in Pebas, Peru, with an average temperature varying between 30°C (86°F) and 21.9°C (71.4°F).

Temperature

During May, the average high-temperature is a still tropical 30°C (86°F), maintaining a close resemblance to that of the preceding month. Pebas's temperature tends to fall to an average low of 21.9°C (71.4°F) during the nights of May.

Heat index

Throughout May, the heat index is computed to be a blistering 40°C (104°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
