💡 Industry Insights & Conversational FAQ

First-Hand Ground Insight for June 2026 Travel:
June marks the beginning of the Southwest Monsoon (Low Season) for the Eastern Gulf (Trat, Koh Kood, Koh Chang). While the Southern Gulf (Koh Tao, Samui) remains relatively sheltered during this period, weather conditions at sea can change abruptly. Boonsiri Ferry operates strictly under maritime safety protocols; therefore, certain vessel departures may be rescheduled, delayed, or swapped based on real-time sea conditions and passenger volume. Recommendation: When booking return trips to catch international flights, always factor in a minimum buffer window of 3 to 4 hours at the airport.

.
