May weather forecast
Cahuita, Costa Rica

Accelerating into May, Cahuita's climate becomes more humid and temperatures level off. A sharp increase in precipitation to 140mm (5.51") signals the beginning of the rainy season, but it fails to overshadow the bright sunlight which shines for about 8.5 hours a day. The wind slows down slightly, yet offers a welcome relief from the humidity. The rainfall enhances the greenery making May a perfect period to enjoy the rich biodiversity of Cahuita.

Temperature

Cahuita's weather, upon May's arrival, documents an average high-temperature of a still moderately hot 29.7°C (85.5°F), nearly identical to the prior month. Throughout May, Cahuita reports a steady low-temperature average of 25.3°C (77.5°F), slightly lower than its daytime counterpart.

Heat index

May's heat index is estimated at a very hot 35°C (95°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression 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 are highly important for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
