Month-by-month fishing outlooks for Bangkok, Andaman, Gulf and the north, based on typical seasonal patterns.
Month-by-month outlooks for each of Thailand's main fishing regions: what the water and weather typically do, which species are usually active, and what the logistics look like.
These are forecasts, not catch reports. Each one is written ahead of the month it covers, drawn from long-run seasonal patterns rather than observed conditions — see our methodology for how they are built. Any given year can depart from the pattern, so confirm conditions with the venue or operator before you travel.
