Peak season:
Trying to figure out the peak season is a little difficult as it isn’t based on the weather. April to October is the best time to fly in regards to the weather, but you’ll find accommodation varies dramatically from one week to the next and cheap flights to Koh Samui will either be easily available, or impossible to find. Koh Samui instead focus their peak seasons on events and school holidays, hotels rates around Easter for example are incredibly expensive, but then a few days later will be extremely cheap again. Your best bet is to decide on a couple of dates you’d be comfortable travelling and then doing any research to see if there are any events, school holidays or bank holidays which would affect the cost of things. Try to avoid Christmas and New Years’ unless you have your flight tickets and hotel room secured well in advance.
Off season:
October and November are the quieter months of the year as the weather isn’t great and can get very wet. You’ll find the cheapest flights to Koh Samui then though so if you’re not a fan of the sunny weather then this would be the perfect time to visit.

If weather is an important factor for your trip to Koh Samui, use this chart to help with planning. For those seeking warmer temperatures, April is the ideal time of year to visit, when temperatures reach an average of 29.0 C. Travellers hoping to avoid the cold should look outside of January, when temperatures are typically at their lowest (around 27.0 C).
May is generally the most pleasant time to visit. Temperatures aren’t too humid and hot but the rain is also a much rarer occurrence. You might struggle to find the cheapest flights to Koh Samui in May however as a lot of tourists do visit the island then. Anywhere from May to late September is great if you’re hoping to take part in diving or other sea activities (although the visibility from Koh Samui isn’t ideal for diving). If you are flexible then you’ll find the cheapest flights to Koh Samui a lot easier. If you have no choice but to travel during a school holiday then make sure you’ve got your flight tickets and hotel rooms booked four, five or even six months in advance to avoid paying hefty prices. Make sure you try to get a window seat for amazing views as you approach. Depending on the direction of the plane the right-hand side could offer slightly better views although nothing worth worrying too much about.
