October weather forecastPuerto Morelos, Mexico

Weather in October

October is the third consecutive heavy rainfall month in Puerto Morelos, with precipitation recorded at 154mm (6.06"). There is a noticeable cool-down in ambient and sea temperature, signaling the start of fall. The longer nights and shorter days also confirm that summer has come to a close. The humidity, though persisting, does not lead to extreme discomfort due to lower overall temperatures. The decrease in daylight hours allows for more comfortable evenings and nights.

Temperature

October records an average high-temperature of a moderately hot 29.5°C (85.1°F), indicating a minor variation from the preceding month. Puerto Morelos, during October nights, records a temperature marginally cooler than the daytime average, at 25.2°C (77.4°F).

Heat index

October's mean heat index is estimated at a very hot 36°C (96.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. 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. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

The average relative humidity in October is 78%.

Take precautions against overexposure. Protection against sun damage is needed. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Notice! The reflection of water and sand increases the UV radiation significantly.
