October, the autumn season in
Xiamen is in full effect. A beautiful amalgamation of warmth, light rainfall and gentle sea breezes, this month retires the high heat of the summer. One striking feature of this month is the sharp drop in the average rainfall, with it plunging to a mere 36mm (1.42"). The pleasantly warm sea remains inviting, making beach activities and sea exploration enjoyable. Combined with the cooling temperatures and receding rainfall, October allows for more outdoor activities and sightseeing opportunities.
Temperature
Xiamen's weather, upon October's arrival, documents an average high-temperature of a warm 27.4°C (81.3°F), nearly identical to the prior month. In October, Xiamen encounters an average low-temperature of 20.3°C (68.5°F) during the night.
Heat index
October's heat index is evaluated at a tropical 30°C (86°F). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.
When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.

Take important precautions because unprotected skin can burn and be harmed swiftly. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades. Even on overcast days, ensure the application and frequent reapplication of sunscreen with at least an SPF 30, especially post swim or outdoor exercise. Caution! Sand and water reflections can notably increase the UV radiation intensity.
