Weather in May

The last month of the spring, May, is another tropical month in El Muñoz, Panama, with an average temperature ranging between min 24.5°C (76.1°F) and max 30.5°C (86.9°F).

Temperature

The transition into May is marked with an average high-temperature of a still tropical 30.5°C (86.9°F), showing an insignificant shift from April's 31.8°C (89.2°F). During the month of May, the nighttime temperature falls to an average of 24.5°C (76.1°F).

Heat index

The average heat index in May is appraised at an extremely hot 40°C (104°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. 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', ties air temperature with relative humidity to produce the perceived temperature sensation. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

A hat with a broad brim is indispensable, filtering out up to half of UV rays.
