January is when most people come to Thailand—and for good reason. The weather is perfect, with temperatures a comfortable 20-30°C (around 70-85°F). It's also peak fishing season, so get out on the water!

The weather and fishing remain excellent, but the crowds start to thin. This could make February the finest month for fishing in Thailand. Tuna, Sailfish, Marlin, and Mahi Mahi are all biting at their best.

The temperature on land is heating up, so you're going to want to head to the water. Giant Trevally is getting more and more rewarding to fish for, while Tuna, Sailfish, and Marlin are still as good as ever for big game anglers. 

April is when Thai people celebrate New Year so enjoy the celebrations before cooling down on the water. Or, get away from it all and go south of Racha Noi to jig for Giant Trevally. Other game fish will also be biting.

The monsoon season hits Thailand. This is not the time for sunbathing, but most exotics in the fishing lakes are loving the break from the heat. Look out for Arapaima, Giant Mekong, and Redtail Catfish.

The south sees a slightly lower amount of rainfall this month, which can make for some more enjoyable fishing. Sailfish are caught out of Phuket in large numbers but be prepared for choppy waters.

Rain picks up along the Andaman coast, but this doesn't put off the Sailfish or the anglers chasing after them. Most charters won't be operating in the Gulf of Thailand until September but lake fishing remains solid.

The brief interlude in the rainy season is over for sure. August is as wet as it comes in Thailand. But the Arapaima, Carp, and Redtail Catfish love it, and it doesn't put Sailfish or Wahoo off swimming the Andaman Sea, either!

The rain starts to die down, especially in the north of the country (although Bangkok is still getting plenty of it). The Gulf of Thailand opens up for business again and Mahi Mahi and Wahoo are biting better than ever.

Saltwater fishing starts to pick up for real and will remain good until January. Head to Koh Kut in the Gulf of Thailand for large numbers of Sailfish. Beware of some rain around the islands.

Tourist season starts to pick up in Phuket and the beaches will stay busy until April. Expect good weather and great fishing, with Marlin, Sailfish, Tuna, and Mahi all biting—not to mention all the exotics in the lakes.

If all you want for Christmas is beautiful weather and excellent fishing, come to Thailand. Expect sunshine, Billfish, freshwater predators, and more. Almost every fish is in season, so come down and enjoy the show!
