The world’s first watersports conditions scoring system

The ocean is constantly changing.

Swell travels thousands of miles. Waves transform as they meet the coastline. Wind, tides and underwater terrain all influence the conditions you’ll experience at your favourite spot.

Making sense of all of this takes more than a simple forecast.

That’s why we built ShorSense™.

ShorSense™ is the intelligence behind every 4Shor forecast. It combines advanced ocean modelling, high-resolution seafloor mapping and sport-specific intelligence to understand how conditions evolve from the open ocean to the shoreline.

The result? Forecasts designed specifically for watersports, helping you plan your next session with greater confidence.

Next-gen seafloor intelligence

We map the ocean’s hidden shape with satellite precision, revealing underwater terrain guiding every wave. 10 m resolution, ~10 cm vertical accuracy, reaching ~40 m depth.

Living open-ocean wave field

Real-time swell intelligence blends ocean sources into a dynamic offshore spectrum, updated twice daily across 24 directions and 30 frequency bands.

How waves transform near shore

Our coastal model carries waves from deep water to shore, capturing how they bend, slow, and break across the nearshore seabed.

Conditions, tuned to you

Ten sport models × four ability levels. Each weights multiple condition variables of wind, wave, period, and tide — calibrated from real sessions on water.
