Weather in October

As October unfurls, a noticeable dip in the wet conditions are evident with rainfall receding to 320mm (12.6"). Tourist-friendly weather starts to resurface as the sea conditions remain enjoyable even with reduced sunshine hours. Although the monsoon’s influence is still prevalent, the daytime temperatures start to drop off. Despite intermittent rain showers, October’s weather makes its way to a more pleasant November.

Temperature

Temperatures in Phuket reach their minimum during September and October, recording an average high-temperature of 31.5°C (88.7°F).

Heat index

For most parts of October, the heat index is estimated at an extremely hot 43°C (109.4°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. 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.

Note: The daily high UV index of 12 in October translates into this advice:
Execute all crucial precautions. Warding off sun exposure is non-negotiable. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Applying and reapplying liberally a broad-spectrum sunscreen of SPF 30+ every two hours, and straight after a swim or outdoor activity is recommended. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
