Weather in May

May introduces Chepo to its peak wet season, mirroring a true tropical rainforest climate. Signifying a significant rise from the preceding month, the rainfall reaches 257mm (10.12"), experienced approximately over 29 days. The consequent uptick in humidity to 85% and cloud cover substantiates the prevalence of the rainy period.

The dawn of May in Chepo sees an average high-temperature of a moderately hot 29.5°C (85.1°F), subtly contrasting with April's 30.5°C (86.9°F). Throughout May, Chepo reports a steady low-temperature average of 25°C (77°F), slightly lower than its daytime counterpart.

Heat index

The heat index value for May is computed to be a sweltering 37°C (98.6°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Note that heat index values are valued for light wind and location in the shade. 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 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of 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 are particularly important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
