Most visitors book Patong for the dry season, and for good reason. But the green season — roughly May to October — has a quieter appeal that regulars know well: emptier beaches, softer prices and afternoon storms that clear as quickly as they arrive.
What is the rain actually like?
It rarely rains all day. The classic pattern is a bright morning, a heavy burst in the afternoon or evening, then clearer, cooler air. Some weeks bring longer grey spells, and September and October are usually the wettest months. Plan beach and boat time early, keep afternoons flexible, and you lose surprisingly little.
The best time to visit guide has a month-by-month table of weather, sea conditions, crowds and prices.
What changes at sea?
The southwest monsoon brings real surf to Patong. Red flags go up more often, and they mean no swimming at all — drownings in Phuket happen mostly in these months. Some boat trips are cancelled for safety, and the Similan Islands national park closes for the season. Calmer swimming is easier at sheltered coves and hotel pools.
Read the beach safety guide before you go in the water.
How do you make the green season work?
- Book refundable rooms and tours: weather can move your plans by a day or two.
- Do island trips early in your stay so you have backup days.
- Keep a rainy-day list ready — a massage, a cooking class, the mall, Old Phuket Town.
- Pack a light rain shell and quick-dry shoes rather than an umbrella.

Is it really cheaper?
Usually, yes. Room rates in the green season are often well below high-season levels, and it is easier to find space on the beach and in restaurants. The trade-off is less predictable weather and sea conditions, so it suits flexible travellers better than people with a single fixed day for a big excursion.
Who should choose the green season?
Travellers who value quiet and space over guaranteed sunshine, people on a budget, and anyone happy to plan day by day. If your trip hinges on a specific boat trip or diving the Similans, choose the dry season instead.
