Temperature

Tumarbong's warmest temperatures are experienced in May, with average high temperatures of 30.6°C (87.1°F) and lows of 27.8°C (82°F).

Heat index

For May, the heat index is computed to be a very hot 38°C (100.4°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

UV index

The months with the highest UV index are January through June, August through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for average individuals.
Note: An average UV index of 7 in May transforms into this advice:
Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Alert! The Sun's UV rays are heightened by the reflection of sand and water.
