Weather in October
Temperature
October's onset records a minor alteration in the average high-temperature to a still moderately hot 83.8°F (28.8°C) from September's 84°F (28.9°C). Fajardo observes an average low-temperature of 80.8°F (27.1°C) during the slightly cooler nights of October.Heat index
October's mean heat index is evaluated at a hot 93.2°F (34°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Heat index determinations are made taking into account the shade and light air movements. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
