A Note On Swimming At The Beach In Phuket During Wet Season

It is not advisable to go swimming in the beaches of Phuket during the wet season (May-October) because of the powerful waves and currents, and sometimes harsh weather. To ensure safety, it is essential to take note of the red warning flags placed on the beaches and adhere to the instructions of lifeguards.

Some beaches may be closed to swimming during certain times due to safety concerns. However, some beaches in Phuket are still protected from rougher waters and may be safe to swim in during the wet season, such as Kata Noi Beach and Kamala Beach.

It is always best to exercise caution and stay informed about the local conditions when swimming at the beach in Phuket in September.

What To Wear In Phuket In September

Being prepared for the likelihood of frequent rain showers and occasional thunderstorms when visiting Phuket during the wet season. You will want to think about adding these items to your packing list for September travel to Phuket:

  • Waterproof footwear: Choose waterproof shoes that can handle wet and slippery surfaces. Flip-flops and sandals can be slippery and uncomfortable during heavy rain.
  • Light layers: Wear light layers that can be easily removed or added depending on the weather. Consider packing a lightweight rain jacket or poncho to keep you dry during unexpected downpours.
  • Quick-drying clothing: Choose clothing made from quick-drying fabrics, such as polyester or nylon. This will allow you to stay comfortable even if you get caught in the rain.
  • Mosquito-repellent clothing: During the rainy season, mosquito activity is higher, and it’s important to protect yourself from mosquito bites. Consider wearing clothing treated with mosquito repellent, such as permethrin, or spray mosquito repellent on your clothing and skin.
  • Umbrella: Carry a compact and lightweight umbrella with you at all times to protect yourself from the rain.
  • Waterproof bag: Use a waterproof bag or backpack to protect your belongings from the rain.

Remember that the humidity level can be high during the rainy season, and temperatures can still be warm. Choose lightweight, breathable clothing that keeps you cool and comfortable in the heat and humidity.
