What Is BalıkTahmini?

Know when the fish will bite with science, not guesswork.

An hourly fishing forecast platform that combines NOAA, HYCOM, EMODnet and Open-Meteo data with species-based biological models for Turkey's coasts. The right bay, the right hour, the right species — and all free.

What feeds the system?

World-class scientific data

Our forecasts aren't raw weather data — they're decisions: they combine hourly-updated global ocean and atmosphere models with Turkey-specific coastal topography and EMODnet bathymetry, and are designed to be validated against real catch reports.

☁️
NOAA GFS

Atmosphere & weather

Global Forecast System: wind, pressure trend, temperature and cloud cover forecast.

🌊
NOAA WaveWatch III

Wave & sea state

Wave height, period and direction — for a safe and productive fishing window.

🌡️
HYCOM

Water temperature

Surface water temperature via Hybrid Coordinate Ocean Model — the key to species activity.

EMODnet

Bathymetry & seabed

European Marine Observation Network: depth profile, seabed structure and fishing pressure.

Open-Meteo

Wind field

High-resolution hourly wind field — animated particle flow on the map.

🌙
Solunar / Astronomical

Moon & sun

Moon phase, moon/sun transits and solunar windows — precise local calculation.

Real catch reports

User catch results are designed to calibrate the model — as data accumulates, the system improves itself.

How does it work?

From raw data to catch score — in 4 steps

For every bay and every hour, a transparent calculation chain that translates raw physical data into the species' biology.

Collect data

For your chosen bay, temperature, wind, swell, pressure, moon and depth data are pulled hourly.

Biological model

Each data point is scored with Gaussian/Tanh/Parabolic curves according to the species' ideal range.

Generate the score

Weighted contributions combine; an hourly 0–100 catch-suitability score is produced for 72 hours.

Calibrate

Real catch reports validate the scoring and automatically fine-tune it over time.

What does it offer users?

Your entire fishing decision in a single tool

Where, when, which species and which tackle — everything you need to make your decision, all in one place.

Hourly catch forecast

72-hour fishing suitability score. It evaluates wind, pressure, swell, temperature and moon phase together.

Modelled species

Every species has its own biology

Instead of a single “general” score, a separate temperature tolerance, depth preference and activity curve is modelled for each species.

Why is it reliable?

Not guesswork — transparent science

No exaggerated promises. Behind every score there is a transparent calculation where you can see how much each factor contributes. The system is designed to calibrate itself against real catch results; its accuracy improves as more data accumulates.

  • Species-specific biological scoring: Gaussian / Tanh / Parabolic curves
  • Will self-improve: designed for automatic calibration with real catch reports
  • Transparent: each factor's contribution to the score is shown clearly
  • Safety first: safe departure window based on wind & swell
What it means for you

Less guessing, more fish

You won't have to open weather apps one by one and interpret them in your head. BalıkTahmini combines scattered data for you and turns the “where should I go this weekend, at what time, and with what?” question into a clear score.

  • Reduces wasted fishing days
  • Lets you explore new bays with confidence
  • Helps you decide on safe anchoring and departure
With you everywhere
