Guayaquil, Panama

The first month of the winter, December, is a tropical month in Guayaquil, Panama, with an average temperature varying between 21.4°C (70.5°F) and 30.3°C (86.5°F).

Temperature

The onset of December manifests an average high-temperature of a hot 30.3°C (86.5°F), demonstrating a minor variation from the preceding month. Throughout the nights in December, Guayaquil experiences an average low-temperature of 21.4°C (70.5°F).

Heat index

During December, the heat index is computed to be a blisteringly hot 40°C (104°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. 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. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Humidity

The average relative humidity in December is 83%.

Fend off overexposure. Sun protection is vital. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
