Fish bite forecast

The system analyses air pressure, temperature, wind and other weather data in real time, then calculates the probability that white fish or predatory fish will bite today at your favourite lake.

❓ Methodology

What affects the bite?

Factors backed by scientific research

Air pressure

The most important factor. Stable high pressure (≥1015 hPa) is ideal for white fish. Falling pressure activates predatory fish ahead of an incoming weather front. Rapidly falling pressure worsens bite activity for all fish.

Stable/rising
Slowly falling
Rapidly falling

Temperature

Optimal temperature for white fish is 15–24°C. Predatory fish are more active at 10–18°C. In winter (≤5°C) activity is minimal; in summer (≥28°C) fish retreat to deeper water.

10–18°C (predatory)
<5°C or >28°C

Wind

Light wind (0–3 m/s) is ideal for white fish. A south-westerly direction is considered most favourable. Strong north-easterly wind worsens the bite. Moderate wind (3–6 m/s) activates predatory fish.

Precipitation

Light rain (0–1 mm) often improves the bite for predatory fish – it reduces visibility in the water. Prolonged heavy rain (≥5 mm) clouds the water and reduces the bite.

Cloud cover

Partly cloudy skies (30–60%) are optimal. On sunny days fish become more cautious. Predatory fish are more active in cloudy weather, when visibility in the water is lower.

0–10% (very sunny)

Time of year

May–June and September are the best months. In spring and autumn fish feed more intensely before and after spawning. December–February is the worst time.

Moon phase

The full moon and new moon create the strongest gravitational pull, which affects water levels and fish activity even in freshwater. During the full moon fish feed more intensely at night. The first and last quarters are considered average.

Frequently asked questions

Answers about fishing and bite forecasts

Yes – air pressure is one of the most important factors. As pressure changes, so does the amount of dissolved gas in the water and the volume of a fish's swim bladder, which affects their behaviour and feeding activity. Stable high pressure (>1015 hPa) is excellent for white fish. Falling pressure ahead of a weather front often triggers intense activity in predatory fish.

Pike bite best in the early morning (5–9am) and in the evening (5–9pm). They are more active in cloudy weather, before or after rain, when pressure is falling. In spring (after spawning) and autumn pike are especially active. The best temperature is 8–16°C. Recommended lures: spoons, crankbaits, soft plastics.

Bream are most active in the early morning (5–10am) and in the evening (6–9pm). They prefer warm water (18–25°C), stable high pressure and light south-westerly wind. In summer you can also fish for them at night. Best bait: worms, maggots, sweetcorn, flavoured bread, boilies. In winter for ice fishing – bloodworm.

South-westerly and westerly wind is considered most favourable – it brings warmer air and creates small waves that oxygenate the water. Light wind (1–3 m/s) is ideal for white fish. North-easterly wind (especially strong) usually means a worse bite. Moderate wind (3–6 m/s) suits predatory fish fishing.

Light rain often improves fishing, especially for predatory fish. Rain reduces visibility in the water, oxygenates it, and can wash nutrient-rich material into the water. However, prolonged heavy rain increases turbidity and can cause flooding, which significantly worsens the bite.

In summer, plant-based baits (sweetcorn, bread, boilies, paste) work great for white fish. Live baits (worms, maggots) work all year round. For predatory fish – soft plastics, small spoons and crankbaits. In warm weather fish often prefer smaller, more natural-looking baits.

In warm summer weather fish retreat to deeper, cooler water (3–6 m and deeper). In the early morning and evening they move to shallower spots (0.5–2 m) to feed. Predatory fish follow their prey and can be at any depth. In winter, look for deeper spots with slower current.

Yes – the moon phase is included in the bite calculation as one of 7 factors. The full moon and new moon create the strongest gravitational pull, which affects fish activity even in freshwater – at this time fish feed more intensely, especially at night. The first and last quarters are considered average. However, air pressure, temperature and wind still have a bigger influence.

Fishing is allowed year-round in Lithuania, but restrictions apply during spawning periods. Pike spawn in March–April, bream in May–June. During these times fishing is prohibited in certain locations. You can find exact restriction dates on the Ministry of Environment or AMT (Environmental Protection Agency) website. Our forecast does not account for legal restrictions.
