Frequently Asked Questions

Ko Samui or Phuket in November for the weather?

In November Ko Samui is at the peak of the rains (average 350-450 mm, rough sea at Lamai), while Phuket enters the dry season (about 150-200 mm, calmer seas at Kata/Karon). Similar temperatures (25-31°C). If you’re traveling in November and want more sunny days, choose Phuket. In Samui plan activities in the morning and keep a buffer day for potential heavy rain.

How to get from Ko Samui to Phuket?

Ko Samui and Phuket are roughly 250 km apart as the crow flies. The fastest option, when it operates, is the direct Bangkok Airways flight USM–HKT: 55-60 minutes, €70-120. The alternative is a ferry + bus combination (Lomprayah or Seatran): ferry to Donsak (about 1h30) and then a bus to Phuket of 4-5 hours, for a total of 6-7.5 hours and €20-30, arriving in Phuket Town. Tip: in high season book 24-48 hours ahead and travel in the morning (08:00-09:00) to arrive before sunset.

Where do you spend less on accommodation and food: Ko Samui or Phuket?

Phuket is generally cheaper: 3* €25-60 versus €40-80 in Ko Samui. Street food is similar: dishes at €1.5-3 in both. Restaurant dinners: Phuket €8-15 (e.g., One Chun), Samui €6-12 (e.g., Khaw Glong) but seafood often costs more in Samui (€15-25). Transport: Smart Bus in Phuket €2.6, in Samui taxis are pricier for short distances (€6-11).

Can you snorkel from the beach without a boat?

In Phuket yes: try Ao Sane (near Nai Harn), Kata Noi, and the south tip of Kata (mask €3-5 per day). In Ko Samui visibility is often low near shore: better trips to Koh Tao/Nang Yuan (1h45-2h by speedboat, €50-75) or to Koh Tan (30-40 min, tour €25-40). Best months for snorkeling: Phuket Feb–Mar, Samui Feb–Apr.

Do you need to rent a scooter or can you get around by public transport?

In Phuket you can use the Smart Bus (€2.6) between the airport and the beaches and the blue songthaews (€1-1.5) between beaches and Phuket Town; Grab works well. In Ko Samui songthaews cover the ring-road loop (50-100 THB), but for secluded beaches a scooter (€5-7/day) or car (€22-35) is convenient. If you don’t ride, plan taxis for key stretches: Chaweng–Bophut €6-9.

What is the best season to avoid rough seas?

For Phuket choose December–March (25-32°C, low waves at Kata/Karon). For Ko Samui prefer February–April (27-31°C, calm seas at Choeng Mon and Lipa Noi).

Popular tours (Phi Phi, Ang Thong) sell out: lock them in 48-72 h beforehand (prices €45-75). In low season you often find last-minute spots, but check the weather and flexible cancellation policies.
