An online cruising guide for yachts sailing around Thailand.

Thailand is home to several distinct geographic regions, partly corresponding to the provincial groups. The north of the country is mountainous, with the highest point being Doi Inthanon at 2,565 metres above sea level (8,415 ft). The northeast, Isan, (see special section on this region) consists of the Khorat Plateau, bordered to the east by the Mekong river. The centre of the country is dominated by the predominantly flat Chao Phraya river valley, which runs into the Gulf of Thailand. The south consists of the narrow Kra Isthmus that widens into the Malay Peninsula.

Thailand has over a 1,000nm of mainland coastline bordering the Andaman Sea and the Gulf of Thailand (Siam). With thousands of islands, there are many more miles of beaches, creeks and headlands meeting the sea. Lying between 5 and 13 degrees north, the climate is tropical, the beaches are palm fringed, with priste white sand,crystal waters and superb coral reefs.

Thailand is largely tropical, so it's hot and humid all year around with temperatures in the 28-35°C range (82-95°F), a degree of relief provided only in the mountains in the far north of Thailand. The careful observer will, however, note three seasons:

  • Cool: From November to the end of February, it doesn't rain much and temperatures are at their lowest, although you will barely notice the difference in the south and will only need to pack a sweater if hiking in the northern mountains, where temperatures can fall as low as 5°C. This is the most popular time to visit and, especially around Christmas and New Year's, finding flights and accommodation can be expensive and difficult.
  • Hot: From March to June, Thailand swelters in temperatures as high as 40°C (104°F). Pleasant enough when sitting on the beach with a drink in hand, but not the best time of year to go temple-tramping in Bangkok.
  • Rainy: From July to October, although it only really gets underway in September, tropical monsoons hit most of the country. This doesn't mean it rains non-stop, but when it does it pours and flooding is not uncommon.

There are local deviations to these general patterns. In particular, the south-east coast of Thailand (including Ko Samui) has the rains reversed, with the peak season being May-October and the rainy off season in November-February.

Customs and Immigration

See the Official Govt. Website for current details.

As of 19 Oct 2015 all foreign yachts entering or leaving Phuket Province must be fitted with a Class B AIS transponder. --Haiqu

We have been in and out of Thailand many times and there is little cost except for weekend overtime at the Immigration places. Also unlike many other places the ship captain cannot check in or out passengers and Crew members. Places like Satun which as a strong river tidal currents should be avoided as all crew and passengers must attend the immigration. Also do not take your time from Langkawi to Phuket as the immigration want to charge a non recieted fee for any delays more than 3 days. You can sit and argue for an hour and get away with it sometimes. --Rossmonty 03:26, 15 June 2008 (MDT)

Gulf of Thailand Coast

Also see Gulf of Thailand. Note that many of the potential stopping places in Thailand on the southern end of the Malay Peninsula aren't good places to stop or stay. There have been rising tension between ethnic (muslim) Malays and Thais in this region, which has resulted in a separatist movement and frequent rioting and bloodshed. So in travelling north and south along this coast it's probably best to skip any ports between Surat Thani or Ko Samui in the north, and the Malaysian port of Kota Bharu in the south.
