Year-Round Season in Phuket and Phang Nga Bay
Generally there are three seasons in Phuket, Krabi, Phang Nga and environs. March, April and May are considered a distinct period because of the heat and humidity. The two accompanying seasons govern activities in the Andaman Sea: the northeast monsoon, which runs from November to May brings consistently sunny weather and calm seas; the southwest monsoon, running from May to October brings the most unpredictable and rainy weather. Temperatures vary between 21 and 34 degrees Centigrade and water temperatures from 26 to 28 degrees through the year.
The weather is generally dry and sunny, seas fairly calm and the sky bright blue. Very good weather for sea canoeing and other watersport activities. Getting hotter towards the end of the month, but still northwest monsoon conditions.
Windsurfing, yachting and dinghy sailing are all recommended during this month. Seas are generally flat and winds between 25 and 30 knots. Skies should be clear and visibility good. Either late February or early March brings in the Chinese New Year (trut jinn in Thai). The exact date depends upon the moon. Due to Phuket’s Chinese influences and the large numbers of Chinese descendants living on the island, the festival is celebrated with fireworks, lion dances, the traditional house cleaning and paying off of debts. Festivities occur all across the island, but are particularly centred in Phuket Town.
The weather generally becomes warmer and more humid, but stil expect plenty of sunshine. For scuba divers, visibility may slightly diminish. But increased plankton counts improve your chance of seeing whale sharks and manta rays. The seas may become to little more lively –perfect for windsurfing, yachting and other sail-driven activity.
The weather conditions generally remain exactly the same as March.
MayGenerally fine weather and calm seas ideal condition. Mid- May sees the weather becomes little less predictable. Phang Nga bay still sheltered from these conditions. On the 15 the waxing moon in the sixth lunar month on Visakha Puja, a public holiday. This is considered to be the date of Buddha’s birth and enattenment and parinibbana(passing away) the festival centers on the local wat (temple) with handle-lit processions.
June is the beginning of the rainy season, although the weather can be as in March. Heavy seas and surf often make some watersports uncomfortable for all but the accomplished sailor, windsurfer or surfer. Often, however, there is a break in the weather which locals call a “mini peak season”. A good time for gamefishing.
Likely to be a little rougher than June, although Phang Nga Bay is still very suitable for generally messing about in boats, or in the water. Some days may be misty, but this adds to the real beauty of its limestone peaks.
A good gamefishing off the sides of outlying islands such as Koh Racha Yai. Heavy seas underdowns and rip tides can make swimming difficult on some beaches- red flags on the beach mean don’t swim under any circumstances. Phang Nga Bay is still fine for most watersports and the east coast of the island is most sheltered-particularly Chalong.
This is potentially the wettest month, along with October, often with gusty winds.
The beginning of the month can be the wettest and windiest but the weather generally improves as November approaches, winds change direction and the northeast monsoon takes over from the southwest.
The from the northwest monsoon means that this time of year is the most perfect on Phuket. This is the beginning of the peak season, lasting until May. Ideal for all things nautical. The Phuket International Sport Fishing Competition is held this month.
The game fishing season has really begun and this is a good time to catch marlin, tuna and sailfish. The weather should still be dry and sunny, with calm seas and a light evening surf:ideal for water-skiing and parasailing. The annual King’s Cup Regatta, a spectacular international event, is held from December 5th – 11th.
