A free bite forecast service. Every day we bring together weather conditions, atmospheric pressure, water temperature, and seasonal fish activity — turning them into up-to-date forecasts for thousands of waterbodies.
How the forecast works
Every day the system pulls fresh weather data and feeds it to our own AI model. It draws on the habits of each fish species and weighs several factors at once:
- Temperature — air temperature, feels-like, and how it changes over the day
- Atmospheric pressure — the current reading and its trend (rising or falling)
- Wind — speed and direction
- Cloud cover and precipitation — coverage percentage, precipitation type
- Time of day — sunrise, sunset, day length
- Seasonality — spawning periods, migration, overwintering

What the forecast includes
For each of the 20 fish species at every waterbody, the model produces:
- Hourly activity — a 24-hour bite curve on a 0–100 scale. Burbot, for instance, is liveliest at night, while chub is most active during the day in clear weather
- Weather analysis — exactly how that day's weather affects a given species' behavior: why rising pressure spurs carp on while a warm night dampens burbot activity
- Best time — the optimal hours and an explanation of why that's the best time to fish
- Fishing tactics — technique tips: slow retrieve for bream, twitching for asp, bottom fishing for catfish
- Lures and bait — what to use: boilies for carp, crankbaits for chub, bloodworms for bleak
- Gear — which rods, clothing, and accessories suit the current weather conditions
Data sources
- Weather — Open-Meteo (open meteorological API)
- Geography — OpenStreetMap (coordinates, polygons, waterbody names)
- AI model — our own forecasting model based on weather data and ichthyological rules
Coverage
The service covers waterbodies of every type and keeps expanding its geography:
- Lakes, rivers, reservoirs, and ponds
- Major rivers broken down by region
- Hundreds of cities and towns
- 20 fish species — pike, zander, perch, bream, roach, crucian carp, and more
Forecast accuracy
A bite forecast is a probabilistic estimate, not a guarantee. Fishing success depends on many things that can't be measured remotely: the waterbody's condition, the food supply, fishing pressure, and personal skill. Our goal is to help you pick a good day and hour to head out — the final word always belongs to the angler.
