Weather in October

As the year progresses to October, Singapore's tropical weather reveals a transition towards wetter months. What sets October apart is a surge in rainfall to 194mm (7.64"), hinting towards increased frequency of showers and thunderstorms. This transition makes the city a little wetter than the preceding month of September. As the skies become occasionally overcast, the essence of a typical monsoon sets in. However, October remains reliably warm and retains its tropical vibe, welcoming tourists into its inviting warmth.

Temperature

The onset of October marks an average high-temperature of a still tropical 31.1°C (88°F), hardly differing from September's 30.9°C (87.6°F). In the month of October, Singapore experiences an average low-temperature of 24.1°C (75.4°F).

Heat index

The heat index value during October is computed to be a scorching 43°C (109.4°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 hold particular significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear. Apply and frequently reapply a minimum SPF 30 sunscreen even on cloudy days, especially after swimming or an outdoor workout. Alert! UV radiation becomes sharper due to reflections from sand and water.
