Bangkok — December 2026 Fishing Report
December is the culmination of Bangkok fishing's annual cycle. The city's coolest month — mornings that actually require a light jacket, crisp dry days with blue sky and northeast breeze — delivers the conditions that transform Bangkok's already-productive pay-lake circuit into something genuinely exceptional. Fish that have been building condition through the November transition are now at their dry-season peak: barramundi fight harder, feed more consistently, and respond to a wider range of presentations than at any other time of year. The Bang Pakong estuary is at prime dry-season condition. And for visiting international anglers arriving in Thailand for the Christmas-New Year holiday, the Bangkok fishing circuit provides a world-class fishing experience within easy reach of the city's hotels and airports.
Water and Weather
December is Bangkok's driest and coolest month, with rainfall typically below 20mm for the entire month. The northeast monsoon delivers cool, dry air that drops Bangkok's morning temperatures to 20–23°C — cold by Thai standards — and maintains afternoon peaks at a comfortable 28–31°C. This diurnal temperature variation produces ideal fishing conditions: cool mornings that activate feeding, warm afternoons that sustain fish activity without heat stress, and clear evening sessions.
Commercial venue water temperatures drop to 24–26°C in December — the coolest of the year and the optimal range for peak barramundi and catfish activity. Water clarity in managed venues improves to its dry-season maximum as turnover slows and evaporation reduces. The December venues are visually beautiful — clear water, cool morning mist over the lake surfaces, excellent light for photography and casting.
The Bang Pakong River is at its dry-season low-water level in December, running clear and slow through the estuary system below Chachoengsao. The mangrove channel system is fully accessible and productive on every tidal cycle.
What's Biting Now
Barramundi — December barramundi at Bangkok pay-lakes is the best of the year. The combination of cool water, peak fish condition, and a wide daily feeding window produces exceptional results for anglers who fish effectively through the morning session. Hard jerkbaits and medium surface lures produce the most exciting December results; soft plastics work throughout the session. Bungsamran's barramundi population is at its most aggressive in December — fish that would require multiple presentations in August take lures decisively on the first cast.
Mekong catfish — Bungsamran's Mekong catfish program continues year-round but December's cooler water produces some of the most powerful fights of the season — the fish are at peak physical condition and the cooler water slows their fatigue, making extended battles on 60–80lb gear particularly demanding.
Mangrove jack — Bang Pakong jack fishing reaches its December peak. The dry-season river clarity brings these fish onto hard lures with an aggression that is notably different from the softer monsoon-season takes. Diving hard lures and surface poppers worked tight to mangrove structure on the incoming tide.
Barramundi (Bang Pakong estuary) — December Bang Pakong barra are exceptionally active on morning surface presentations. The estuary's low, clear December water makes the fish visible in the mangrove channel sections — sight-fishing opportunities are possible in the clear-water creek mouths on the first hour of the incoming tide.
Snakehead (managed venues) — Giant snakehead in commercial venues including IT Lake and Boon Mar are at their coolest-water behaviour: tight to structure, deliberate in feeding, but very catchable on the right presentation. Slower-retrieved surface lures and subsurface jerkbaits worked along wall edges and pontoon shadows.
Arapaima — The large managed arapaima at Bangkok commercial venues are active year-round but December's cooler water activates their surface-feeding behaviour — large poppers and wake lures on heavy gear produce dramatic topwater takes from these massive fish, which can exceed 150kg in the best-stocked venues.
Striped catfish — Available at all venues on all methods, year-round reliable. December versions are slightly more active and feed through a longer daily window than their monsoon-season equivalents.
What to Target This Month
Top pick: Bang Pakong full-day Christmas holiday session. For visiting anglers in Bangkok over the Christmas period, a day trip to the Bang Pakong estuary is Bangkok's best natural fishing experience. Drive to Chachoengsao (90 minutes from Bangkok centre), pick up a charter from the riverside pier operators, and fish the morning incoming tide from 7 am through 11 am. The December estuary's barramundi and jack fishing, combined with the atmospheric mangrove channel environment and the pleasant December weather, makes this a fishing day that rewards the effort significantly. December estuary sessions frequently produce Bangkok's best wild-water barra catches of the year.
Second pick: Bungsamran Lake Christmas week barramundi. The Christmas week crowds at Bungsamran are manageable on weekdays. A 5:30 am start on a Tuesday or Wednesday in the 22–26 December period, arriving to clear morning mist, perfect water temperature, and active barramundi that have been feeding since first light, is quintessential Bangkok cool-season fishing. Pack a jerkbait selection (10–14cm sinking and suspending models in natural colours) and plan to fish seriously through to 10 am.
Third pick: New Year's Eve session at Pilot 111 or IT Lake. For the New Year period, the outer Bangkok venues offer an alternative to Bangkok's central celebrations. An evening session on New Year's Eve at Pilot 111, starting at 4 pm and fishing through sunset and into the early night, includes the ambient fireworks display from the surrounding suburbs as a free backdrop to what is consistently one of the year's most active evening barra sessions. December 31 surface barra at 6 pm, with distant fireworks reflecting in the lake, is a Bangkok fishing memory worth making.
What to Avoid
Avoid Bangkok's peak-holiday-traffic days (24–25 December, 31 December–1 January) for road travel to outer venues — expressway congestion during the holiday period can make a 90-minute Bang Pakong drive into a 3-hour ordeal. Travel to all venues before 7 am or after 9 pm on major holiday dates. Avoid Bungsamran on peak weekend days in December if bank access is your priority — arrive at opening time (5:30 am) or book advance bank positions. Avoid fishing from unlit canal-side locations in the outer Bangkok districts at night without local guidance.
December Dawn at Bungsamran
The defining Bangkok fishing moment of the cool season is the Bungsamran December dawn. You arrive in darkness, set up on your preferred bank position before the sky lightens, and cast to the dark water while the city slowly illuminates around you. The lake surface mists slightly in the cool air. Then, as the first pink light edges the Bangkok skyline, a barramundi hits the jerkbait with a take that echoes across the quiet water. That first December barra, in the cool dawn air with the city waking behind you, is the reward for understanding why Bangkok remains one of the world's most remarkable fishing cities.
Venue Spotlight
Bungsamran Lake (Min Buri, Bangkok) — December's coolest month produces the best conditions in Bungsamran's storied history. The venue's large Mekong catfish, active barramundi, and comprehensive facilities combine in December conditions that regularly produce Bangkok's highest-quality tropical sport fishing. International visitors from the UK, Australia, and Europe who time their Thailand trip around the cool season consistently describe December Bungsamran as exceeding their expectations.
IT Lake Monsters (Pathum Thani) — IT Lake's diverse stocking program, which includes arapaima, alligator gar, barramundi, and multiple exotic species, is at its December best. The cool water activates the arapaima's surface feeding, producing dramatic topwater encounters that are a Bangkok must-do experience. The venue is approximately 40 minutes north of central Bangkok via the Vibhavadi-Rangsit corridor.
Bang Pakong Estuary — Chachoengsao — The provincial town of Chachoengsao provides the best December wild-fishing experience in the Bangkok region. A two-day Chachoengsao trip — combining a full morning estuary session on day one with an afternoon exploring the town's temples and riverside restaurants, and a second morning session before the drive back — is one of December's most satisfying Bangkok fishing configurations.
Logistics in December
December in Bangkok means peak-season accommodation pricing across the city from around 20 December through 5 January. Book central Bangkok accommodation well in advance for the Christmas-New Year period. Expressway tolls and fuel are the only practical transport costs for self-drive venue trips. The major pay-lakes maintain full operations through the holiday period including December 25 and January 1 — both are popular fishing days. Bangkok's Suvarnabhumi Airport handles the international arrivals; Don Mueang handles domestic and low-cost carriers.
Looking Ahead to January
January continues December's cool-season peak without interruption. January is arguably Bangkok's finest fishing month — the coolest temperatures, the most active fish, and the highest concentration of visiting international anglers taking advantage of the tropical dry season from a northern hemisphere winter. Book January pay-lake visits well ahead and plan Bang Pakong estuary trips for the January neap tide periods when the river's tidal exchange is at its most productive.
