Where to stay on Koh Samui in December?

Koh Samui in December: Weather, What to Expect and December FAQs

The December holiday period is peak-peak-peak season on Koh Samui. Villas tend to book out months in advance, and many resorts require a 7-night minimum. As such, if you’re booking last minute and find availability at somewhere you think looks nice – book it. It won’t be there when you return after “thinking about it”. By October, many resorts only have availability in their most expensive room categories. (But a 176 m² villa with a private pool doesn’t sound like the worst news, right?)

Views vs beachfront accommodation

Koh Samui in December: Weather, What to Expect and December FAQs

December is the tail-end of Koh Samui’s rainy season and perfect blue-sky weather isn’t guaranteed. The ocean can be rough and, on many beaches, the tide comes up quite high at this time of year. As such, you might prioritise properties with ocean views over beachfront accommodation. This way you get to enjoy the ocean in any weather, without paying premium prices for a beach you might not be able to use every day.

Christmas

If you’re coming to Koh Samui for Christmas, rest assured: just about every restaurant on the island will have a Christmas dinner of some description (at every price point). If you have your heart set on a table with a particular view, do book as early as possible! While Christmas is very much an adopted holiday in Thailand, the decorations are nothing short of delightful.

New Year’s Eve

Plan to celebrate New Year on  Koh Samui? Expect to repeat much the same as above (an enjoyable process), hopefully with yet more champagne and a lot of fireworks.

Champagne for New Year’s Eve? Note that import taxes make champagne cra-zy expensive in Thailand. Compare a 75cl bottle of Duval Leroy: Koh Samui supermarket price: £82 (3,599 THB) vs Amazon UK price: £34.99. Yikes. Just a cool 234% markup. Bring your own, but pack it in your suitcase rather than buying duty-free and hand-carrying it with you into Thailand.

If you’re connecting in Bangkok they will confiscate duty-free liquids over 100ml … no matter how officially it’s sealed. Don’t blame the messenger. The same price disparity applies to any imported alcohol – wine, port, etc.

Packing lists and dress code advice

It’s a hectic time of year, but packing is the final step before nothing but gluttony and lazy days. For a massive head-start, see:

Mosquito repellent

Mosquito Repellent Bracelets + Incognito Anti-Mosquito Spray + Anti-Insect Loofah Soap

If you’re going to forget anything in your pre-departure frenzy, let it be a small blonde child named Kevin and not your mosquito repellent. Given Koh Samui’s high humidity in December (as rainy season wanes) – mosquitoes get very greedy for their Christmas dinner. The bits above are my tried-and-tested favourites for completely avoiding mosquito bites in Thailand. All three are DEET-free and totally natural.

For more mozzie-avoidance tips – here’s everything I know.

Travel adapters

UK to Thailand Travel Adaptor

If you’re coming from the UK, note that you will need a travel adapter for Thailand. Thai plugs come in two shapes and sizes (two flat pin, like the U.S., and two round pin – pictured here). I always recommend the adapter below as it’s (A) earthed and (B) comes with a metre-long lead … so you can charge your stuff on a table rather than on the floor/behind a bedside table/wherever the hell your hotel has put a plug.

Rainy season (should be) over! In later December we officially say goodbye to Koh Samui’s rainy season and celebrate the re-opening of Angthong Marine Park (typically December 23rd).

Does it rain on Koh Samui in December?

Koh Samui in December: Weather, What to Expect and December FAQs

Yes. But I’ll sugar-coat it. You’re far likelier to see heavy, consistent rain in early December than towards the Christmas/New Year period. In fact, the chance of rain in a day falls by half from Dec 1 to Dec 31. December is by no means the hottest point of the year, nor the sunniest, but the tropics have a fairly liberal rain policy year-round.

Your rainy day contingency plan

Given the likelihood of seeing some rain in December, I really recommend bringing some fun stuff to bust out on rainy days. Especially if you’re coming with kids (or men-children).

Whether games, books – even colouring books – it’s great to bring back-up for anyone in your group who gets bored easily. And then whinges about it. More games for them = more uninterrupted cocktail time for you.

Should you spot rain on the forecast, don’t worry. Thailand has fantastic rainstorms; enjoy them best with a good book or a family travel game (and a Singha or coconut shake sourced nearby).

Things to do on Koh Samui in December?

Lazy days

Inflatable Champagne Bottle Pool Float

In no particular order, my favourite things to do on Samui in December are: eat and drink a lot, watch Love Actually, laze around and look at Pinterest read quality literature and – most of all – enjoy time with family. On Koh Samui, I like a mixture of about 20% scheduled activities to 80% “let’s see what happens today”. If it involves something alcoholic happening in a coconut, so much the better.
