November is the month many Bangkok anglers look forward to most. After months of grey skies, high humidity and unpredictable downpours, the first breath of the cool season arrives like a reward for patience — and the fishing tends to respond in kind.
Weather and Water Conditions
The transition from monsoon to cool season is rarely an overnight switch, and November 2025 illustrated that well. The opening weeks continued to see periodic heavy showers, particularly in the north of the metropolitan area, keeping water levels elevated and some venues carrying a residual turbidity from the wet-season runoff. By mid-month, however, the rain systems had retreated northward, skies opened and daytime temperatures began to settle into the low-to-mid 30s Celsius — still warm by most definitions, but a meaningful drop from the oppressive heat of September.
Water temperatures across the pay-lakes eased toward the 28–29°C range by month's end, a shift that experienced anglers consider something of a trigger event for the larger species. Dissolved oxygen levels improve, fish metabolism becomes more predictable and feeding windows that were erratic through the wet season begin to consolidate around dawn and dusk.
Freshwater Pay-Lake Roundup
Bungsamran Lake
The dawn-platform regulars at Bungsamran reported steady catfish numbers through the second and third weeks of the month as conditions stabilised. Giant Mekong catfish were showing well across the deeper central sections of the lake, with multiple-fish sessions becoming the norm for anglers willing to put in full-day visits. The improving water clarity also gave lure anglers more confidence, and there were scattered reports of aggressive strikes on large swimbaits during the low-light periods.
Paste and dough baits continued to account for the bulk of the catfish, as they do throughout the year, but the addition of floating bread crust rigs — a technique that tends to come into its own once surface temperatures drop — brought some encouraging results from the carp-oriented platforms.
IT Lake Monsters
Specimen-anglers at IT Lake Monsters had a productive run on arapaima as water temperatures stabilised through the back half of the month. The venue's arapaima are notoriously sensitive to sudden environmental changes, and the gradual, steady cooling of November appears to suit them well. Reports from the lake described consistent surface activity during the early morning hours, with fish rolling and occasionally breaching — a reliable indicator that the arapaima are feeding confidently.
Giant Siamese carp were also in good form, with several anglers targeting them on floatfished bread and pellet-suspended rigs on the calmer eastern bank.
Pilot 111, Boon Mar and Bang Na
The smaller venues around the greater Bangkok area also showed improvement as the month progressed. Pilot 111 saw reliable barramundi action, particularly on surface lures worked around the shaded margins in the hour after dawn. Boon Mar and Bang Na both produced consistent catfish and smaller carp for anglers seeking a more low-key day out, with shorter session times and no-booking walk-in access making them popular with local weekday regulars.
Lure vs. Bait: November Observations
November is one of the few months in Bangkok where lure fishing genuinely begins to close the gap on bait. With clearer water and more active predatory fish, lure anglers who had struggled through the murky wet-season months started to find their footing again. Surface lures, large soft plastics and weedless frog patterns all contributed to reports from the smaller natural canals and overflow lakes on the outskirts of the city.
At the major pay-lakes, bait remained dominant simply by volume of fish available, but the consensus among regulars was that November represented the start of a more balanced period for presentation choices.
"The moment the skies clear and the water drops even a degree or two, you can feel the whole lake shift — the catfish start moving earlier, the carp are up in the water and everything just feels more alive."
Looking Ahead: December 2025
December historically marks peak cool-season fishing around Bangkok. Temperatures will ease further, early-morning mist becomes common and fish across all the major venues tend to feed aggressively through the cooler hours. Visiting anglers over the Christmas and New Year period will find conditions close to ideal, though weekend platforms at Bungsamran and IT Lake Monsters can fill quickly over the holiday stretch.
Book weekend sessions at IT Lake Monsters and Bungsamran well ahead of the Christmas and New Year holiday period — these dates are the most in-demand of the entire year.
Recommendations for Visiting Anglers
For those planning a Bangkok fishing trip in November, particularly in the second half of the month, conditions are increasingly in your favour. Dawn starts remain the most productive window — arrive at the lake gate as it opens and secure a platform before the light fully breaks. Bait options are broadly forgiving at this time of year, but a selection of paste, pellet and dough is advisable alongside any lure kit you choose to bring.
Insect repellent remains essential through November even as temperatures cool, and a light layer for the pre-dawn hours is now worth packing. The cool season brings comfort on the bank, but it also brings longer, more productive days — and there are few better places to spend one than on a Bangkok pay-lake as Thailand's finest fishing months begin in earnest.
