Cerro Largo, Panama

The last month of the spring, May, is also a hot month in Cerro Largo, Panama, with an average temperature varying between 23.5°C (74.3°F) and 31.3°C (88.3°F).

Temperature

At the onset of May, Cerro Largo records an average high-temperature of a still tropical 31.3°C (88.3°F), showing little deviation from the preceding month. During May, the nighttime temperature averages to a warm 23.5°C (74.3°F).

Heat index

May's average heat index is estimated at an extremely hot 43°C (109.4°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.
Data suggests that the heat index is set for environments in shade and with a light wind. 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 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

In May, the average relative humidity in Cerro Largo is 83%.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
