Best Time of Year to Visit Lý Sơn Island: A Month-by-Month Guide

The best time of year to visit Lý Sơn Island is from April to August. During these months, the weather is sunny and the seas are calm. Boat transfers from Sa Kỳ Port are safe and reliable. From September to February, the central coast of Vietnam enters its monsoon and storm season.

Visiting Lý Sơn Island between September and February is highly risky due to unpredictable monsoon weather. Heavy rains, tropical depressions, and storms often hit Quảng Ngãi province during this period. Ferry operations can stop for several days or even weeks, leaving travelers stranded on the island. However, late November to December is also the local garlic planting season. The volcanic fields turn green, offering a unique landscape. If you plan to visit now, check weather forecasts daily and consult with Trip2VN to adjust your itinerary.

The famous Lý Sơn garlic harvest takes place from late January to early March. During these months, the island is busy as farmers harvest garlic bulbs from fields covered in volcanic soil and coral sand. The weather is cool, with temperatures between 20°C and 26°C, though the sea can still be choppy. Travelers can buy fresh garlic directly from local farmers at markets near Cầu Cảng. Prices for traditional multi-clove garlic start from $5 (approximate) per kilogram. For current ferry schedules during this transitional season, please contact Trip2VN.
