Fishing Calendar for August 2026: Night Fishing Times and Changes in Fish Behavior
August is a transitional month for bodies of water, marking the end of the summer season and gradually preparing the underwater inhabitants for fall. In the first half of August, air and water temperatures will remain high, so fish will remain sluggish during the day and switch to feeding at night or at dawn. However, starting in the second half of the month, when nights become noticeably cooler, the water begins to cool down and become enriched with oxygen. This stimulates increased activity in both non-predatory fish, which are trying to build up fat reserves before winter, and predators, which are entering their early fall feeding frenzy.
Fish Behavior in August
The Impact of Temperature and Oxygen Levels
In August, algal blooms continue in still bodies of water (lakes, ponds, reservoirs), which reduces oxygen levels. On hot days, fish move away from shallow waters and seek deeper areas, pits, spring outlets, or sections with fast currents. Fish venture into shallow waters only at night and at dawn, when the water cools slightly.
Changes in the Food Supply
By the end of August, underwater vegetation begins to die off and become coarse. Fry that have grown over the summer become the main prey for predators. Non-predatory fish gradually lose interest in purely plant-based baits (straw, oilcake, corn) and begin to prefer animal-based food (maggots, earthworms, bloodworms, manure worms).
Fishing Prospects by Fish Species
Carp and Sazan: In early August, they are best caught at night or at dawn using bottom rigs (feeder, flat feeder). Bait options include boilies, corn, and peas; by the end of the month, try combined “sandwich” baits with added maggots.
Bream and Silver Bream: August is the ideal time for night fishing for bream using a feeder in deep sections of rivers and reservoirs. Bait: a bunch of worms or maggots with a piece of foam to lift the hook above the silt.
Crucian carp: Catches remain steady throughout the month, though they become finicky during the day. The best times are from 4:00 to 8:00 a.m. and from sunset to midnight. They respond well to groundbait and dough, and as the weather cools, to red worms.
Roach and rudd: They bite actively on float rigs along the edges of reeds and water lilies. For roach, groundbait, semolina paste, and steamed wheat work wonderfully.
Pike: In the first half of the month, it hides in dense algae or at depth. At the end of August, as water temperatures drop, they begin to feed actively. Silicone lures, spoons, and minnow-style wobblers work best.
Zander: The main target for night and evening fishing. At night, it ventures onto sandy shoals and sandbars to hunt for fry, where it can be caught on wobblers with a shallow diving action. During the day, it stays in deep pools and among snags, where it responds to silicone lures when jigging.
Perch: In August, it forms large schools and creates so-called “boils,” driving fry to the surface. At such times, it is easy to catch using poppers, spinners, and micro jigs.
Catfish: At the beginning of the month, there’s still a good chance of catching catfish at night using a quack lure or bottom-fishing rigs baited with a bundle of earthworms, live bait, or fried bird liver.
Decade-by-Decade Fishing Calendar for August 2026
First Decade (August 1–10):
Typical summer conditions. Daytime fishing is not very effective. The main focus should be on night and morning fishing. The priority is feeder and bottom fishing for carp, bream, and crucian carp in deep water or in currents.
Second Decade (August 11–20):
A period of relative stability. The daytime heat subsides, and perch and walleye become more active at dusk. Non-predatory fish begin to respond better to baits containing animal ingredients and scents of spices or bloodworms.
Third Decade (August 21–31):
The start of fall activity for predatory fish. Nights become cold and foggy. Pike and perch begin to hunt actively throughout daylight hours. Baits for non-predatory fish shift almost entirely toward animal-based options (worms, maggots).
Bite Calendar by Moon Phases
The phases of the moon have a significant impact on gravitational processes and the behavior of aquatic life.
High activity (Excellent Biting):
The waxing moon phases and the days leading up to the new moon and full moon (approximately August 4–8 and August 19–24). On these days, fish actively seek food and take the bait eagerly.
Moderate activity (Moderate Bite):
The waning moon phase (August 10–16). Bites are steady, but fish become more selective regarding line thickness, hook size, and bait presentation.
Low activity (Weak bite / Lull):
New Moon and Full Moon days. During these days, atmospheric pressure and light levels change drastically, making the fish passive.
Tips for a Successful August Catch
Experiment with baits: In August, fish often change their preferences during a single fishing trip. If corn worked in the morning, by lunchtime crucian carp or bream may demand only maggots or a combination of both.
Precision in baiting: Due to the abundance of natural food in the water, it’s hard to entice fish with large amounts of bait. Use fine-grained bait that creates a cloud of turbidity and scent without overfeeding the fish.
Choosing Tackle for Clear Water: By the end of August, the water becomes clearer and more transparent. Reduce the thickness of your leaders (to 0.10–0.14 mm for non-predatory fish) and use invisible fluorocarbon lines.
Keep an eye on the wind and barometer: Wind blowing toward the shore carries food and oxygen-rich water there, making the coastal zone attractive to fish. A slow drop in atmospheric pressure before rain often triggers a brief surge of extremely active predator bites.
