October weather forecast
Arraiján, Panama

As Arraiján moves into October, it experiences the turning of weather seasons with rainfall seeing an unexpected surge to 221mm (8.7"). This shift in monsoon characteristics challenges the gradual descent seen towards the end of September. Degrees of atmospheric pressure, daylight hours, and daylight intensity see minor adjustments. Despite the slight drop in temperature lows, high humidity remains a constant. Essentially, October is notable for an unanticipated resurgence in rainfall intensifying the tropical weather attributes.

Temperature

Arraiján, Panama, marks the arrival of October with an average high-temperature of a still moderately hot 28.7°C (83.7°F), hardly different from September's 28.9°C (84°F). A mean low-temperature of 24.3°C (75.7°F) is anticipated during the month of October, a slight step down from the daytime high.

Heat index

Throughout October, the heat index is appraised at a very hot 35°C (95°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

In October, the average relative humidity is 86%.

The months with the lowest UV index are January through December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for average individuals.
Note: A maximum high UV index of 7 in October translates into the following recommendations:
Ward off overexposure. Defence against solar harm is crucial. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
