May weather forecast
Niltepec, Mexico

The last month of the spring, May, is another tropical month in Niltepec, Mexico, with an average temperature varying between 34.4°C (93.9°F) and 25.1°C (77.2°F).

Temperature

The average temperatures reach their apex in May, averaging 34.4°C (93.9°F) at the high end and 25.1°C (77.2°F) at the low end.

Heat index

May's average heat index is calculated to be a burning hot 45°C (113°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. 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. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
