Temperature

Culion's warmest month, May, generally records average temperatures ranging from a high of 30.5°C (86.9°F) to a low of 28.5°C (83.3°F).

Heat index

For most parts of May, the heat index is estimated at a torrid 37°C (98.6°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
