The forecast comes from Open-Meteo, the same source credited in this page's live weather dataset.

It shows the live Open-Meteo forecast for Koh Lanta, not a historical or seasonal climate average. The figures reflect the current forecast and change as new data comes in.

The forecast is refreshed through the day, so the page reflects the latest reading from Open-Meteo rather than a fixed daily snapshot.

July sits in the middle of Ko Lanta's southwest monsoon season, which runs from roughly May to October. Expect temperatures around 27–31°C with high humidity and regular afternoon showers or short downpours. The island is quieter and cheaper than peak season. Mornings are often clear enough for beach or outdoor activities.

Ko Lanta's wet season runs from approximately May to October, driven by the southwest monsoon off the Andaman Sea. October and November are typically the wettest months. Rain usually arrives as short, heavy afternoon showers rather than all-day drizzle, so mornings are often dry.

The driest and clearest weather falls from late November through April, when the northeast monsoon keeps the skies mostly clear. December to February is the most popular window: sea conditions are calm, diving visibility is high, and daytime temperatures sit around 25–32°C.

Year-round temperatures on Ko Lanta range from around 24–25°C at night to 31–33°C in the afternoon. Humidity pushes the feels-like temperature higher, especially during the wet season. The live readings on this page reflect the current temperature and feels-like figure.

Many visitors find the low season (May–October) worthwhile: prices drop noticeably, the island is far less crowded, and the landscape turns lush and green. Rain typically comes in short, heavy bursts. Diving and snorkelling are limited by rougher sea conditions, but beaches are uncrowded and accommodation rates are significantly lower.

Sea surface temperature around Ko Lanta stays warm throughout the year, typically ranging from 28°C to 31°C. The current reading from the Andaman Sea appears in the marine panel on this page.

Ko Lanta and the wider Andaman coast are not in the typhoon belt that affects the Gulf of Thailand and the Philippines. However, the southwest monsoon (May–October) can bring sustained storms, strong winds, and rough sea conditions. Any active weather alerts for Ko Lanta are displayed on this page.

All three destinations share the same Andaman coast seasonal pattern — wet from May to October, dry from November to April — so their weather moves largely together. This page shows live forecasts for Ko Lanta, Krabi, and Phuket side by side so you can compare current conditions directly.
