    What's the Weather like in Ko Samui in December 

    Temperature

    December marks the end of the monsoon season and the beginning of the dry season in Ko Samui. This is also the cooler part of the year, although cool has to be taken with a big grain of salt. The average temperature is 27°C, only three degrees less than May, the hottest month of the year. The average daily low temperature in December is 24°C; the average daily high is 29°C, both exactly the same as November. These temperatures don't seem to change at all in the course of the month.

The temperature of the water in the Gulf of Thailand ranges around 27°C, allowing for a very pleasant dip in the sea.

    As the weather moves towards the dry season, the skies start to clear. The beginning of December is characterised by 85% of cloud cover, which means mostly cloudy skies, but by the end of the month it has dropped to 78% partly cloudy skies. Clearing skies, of course, also result in an increase of sunshine.

December is the fourth-wettest month of the year, after the monsoon months of October and November, and May. There are still nine days of rainfall in the course of the month, a number that is shared with May, June and July. The chance that you will experience rain varies throughout the month. In the beginning of the month there is a daily chance of 47% that rainfall will occur; by the end of the month that chance has decreased to 37%. The types of rainfall that are observed are light rain, moderate rain and thunderstorms. Light rain is the most common type, with a 47% chance on any rainy day. Moderate rain is second-most common and is experienced on 27% of the days of precipitation. Thunderstorms occur on 24% of the rainy days.

    Ko Samui Beach for December 

    Ko Phangan

    One of the most famous islands in Thailand is Ko Phangan. It is located only 12 kilometres from Ko Samui and is the country's fifth-largest island. You can only reach it by ferry from the mainland or Ko Samui. This island is virtually unspoilt and consists of dense jungle and long white sandy beaches. The surrounding waters are home to more than twenty diving sites and the beaches and bays can't get more tropical than this.

    The island's biggest claim to fame, however, is that it is home to the (in)famous Full Moon Parties, huge monthly beach parties that reach their yearly climax at New Year's Eve with crowds ranging between 10,000 and 30,000 people.

    Bars and Restaurants 

    Bondi Aussie Bar & Grill

    The Bondi Aussie Bar & Grill in both Lamai and Chaweng has nothing to do with Thai food, but it sure is a fun place to hang out. It is part of a chain in Thailand; there is another restaurant in Phuket. In Lamai, Bondi Bar is located amidst all activity, opposite the crowded Central Plaza and its bars and outdoor Thai Boxing ring. Bondi Bar is located in a separate one-storey building and is a lively watering hole where you can watch Premier League football and other sports or listen to live music. There is a large selection of cocktails and beers, and the food is great. The menu consists of classic pub food, such as burgers, fish and chips, pizza, steak, barbecue ribs and pasta.

    Kobori Japanese Restaurant

    Another restaurant that serves foreign food is Kobori Japanese Restaurant in Maenam. This is often regarded as the best Japanese restaurant on the island and is located in a two-storey building on Maenam's Walking Street. Its interior is in a sober Japanese style and the menu contains a wide choice of sushi, sashimi and teppanyaki. The restaurant is also known for its selection of Sake.

    Things to do in Ko Samui in December 

    Aquapark Chaweng

    As the skies begin to clear and the amount of sunshine rises, December is a great time to visit Aquapark Chaweng. This waterpark is a fun beach and water activity to do with a group of friends or with your family. Located in central Chaweng, it is easily accessed from anywhere in town. Aquapark Chaweng features giant inflatables in the sea off Chaweng Beach. These floating devices include a five-metre-high white iceberg wall that you can climb and slide down off, a huge trampoline, human catapults, a spinning green log and much more. People who can complete the wipe-out course win free prizes. This is a place that offers an afternoon of fun to kids, but also adults. You can hold birthday parties, as well as hen and stag parties. Prices are per hour and affordable, and safety is always a priority as you must wear a life-jacket at all times.

    Big Buddha Temple

    For culture you should visit the Big Buddha Temple, located on a little island on the northeast coast of the island. This is in fact one of the most popular attractions on Ko Samui. The big Buddha Temple is known among locals as Wat Phra Yai and features a huge 12-metre-high golden statue of the Buddha, which can be seen from several kilometres away. The island is connected to the mainland by a causeway.

    This is a sacred site and you are asked to dress appropriately when visiting. The courtyard underneath the statue is always filled with vendors selling souvenirs, amulets, clothing and all kinds of artefacts. You can grab a bite to eat at one of many food stalls as well. The best time to visit is in early morning, when locals go there to offer food and flowers and light incense at the statue's base. This is also when the monks do their morning chanting. At night Big Buddha is covered in spotlights, creating a striking and truly exotic sight.

    Ko Phangan

    One of the most famous islands in Thailand is Ko Phangan. It is located only 12 kilometres from Ko Samui and is the country's fifth-largest island. You can only reach it by ferry from the mainland or Ko Samui. This island is virtually unspoilt and consists of dense jungle and long white sandy beaches. The surrounding waters are home to more than twenty diving sites and the beaches and bays can't get more tropical than this.

    The island's biggest claim to fame, however, is that it is home to the (in) famous Full Moon Parties, huge monthly beach parties that reach their yearly climax at New Year's Eve with crowds ranging between 10,000 and 30,000 people.
