The Big Blues, weather and sea conditions in SE Asia

Thailand has year round tropical climate with an overall average humidity of 66% to 82%.

In Phuket there are only two seasons, a dry and a summer, with small temperature differences between the two. The NE monsoon season from November till the end of April and the SW monsoon season from May till the end of October.

The NE wind is the dry sunny offshore breeze weather, the SW wind is an onshore wind and brings some rains in from the Indian Ocean.

Sunny skies, nice breezes and moderate temperature characterize the cool season and this is the driest time of the year. During this period also the sea conditions are usually excellent.

Phuket is incredibly fortunate, as extreme weather and sea conditions are uncommon. Very few fishing days are lost in fact due to heavy seas or tropical storms.

In the summer season, particularly during September and October it might be raining for some time but prolonged periods of heavy rain only occur occasionally. Yet extended periods of sunshine and blue skies are more than common. As a matter of fact several anglers prefer to show up at this time, as crowds are thinner and the overall climate is pleasant.

However due to a combination of uncertain weather and sea conditions during the summer season we do not operate live-aboard trips to the Similan or Koh Rok/Koh Ha Islands.

Also the Andaman Island and Burma Banks' tropical climate is influenced by the southwest and northeast monsoons. Because of this reason there is a relatively short window to make a safe transfer trip over there to operate our fishing expeditions; it goes in fact from January/February till the beginning of April each year.

Day trips are available year round and as a matter of fact the SW monsoon season is excellent for Sailfish and Wahoo which can be caught around the Racha Yai and Racha Noi islands nearby Phuket.

On the other hand in Kuala Rompin the Sailfish season runs from April to November with the peak season from July till end of November.

Southwest monsoon in fact does not affect Kuala Rompin coast much as it is sheltered by the nearby mountains; however, do expect occasional heavy rain and windy conditions.

Kuala Rompin is situated near the equator so temperature might hit high of 35 C during the day and low of 25 C at night. Then again mid November to March is the start of the northeast monsoon which often brings strong rainfall so this season is not recommended for fishing in Kuala Rompin due to strong wind and choppy conditions.

Finally overall sea surface temperatures in the area are generally warm year round, ranging from 79 to 84 F (26 to 29 C).
