The honest truth
You surf a lot.
But are you improving?
Most surfers can tell you how many sessions they did this year. Almost none can tell you if their wave speed improved, which board performs best at their favourite spot, or why they felt flat last Tuesday. OceanLog answers all of it.

Real data from a real surfer. This is what OceanLog looks like after 7 years.
Your spots — not someone else's
Every spot you surf.
Every time you surf it.
OceanLog tracks your favourite spots, your best sessions there, which board worked, what the conditions were. Not generic — yours.

The science behind your surfing
The Surf Energy Triangle
Three energy types interact on every wave. OceanLog measures all three — so you know exactly why some sessions feel electric and others feel flat.
⬆️
Potential Energy
Your position on the wave. Height at the lip before a turn. The higher you are, the more PE available to convert into speed and manoeuvres.
→ Track: wave selection, positioning, take-off angle
⚡
Kinetic Energy
Board speed from your watch. Your avg/max speed ratio reveals if YOU are generating speed — or if the wave is doing the work for you.
→ 70%+ ratio = you're generating. Under 55% = the wave is.
🔋
Chemical Energy
Your biological fuel. Muscle power, paddle fitness, HR recovery between waves. CE depletion is why wave 10 feels different to wave 1.
→ Track: HR, sleep, fitness. Know before you paddle out.
Your quiver — not a generic board guide
41 boards tracked.
Every one understood.
OceanLog knows every board you own or have ever ridden — rocker, concave, tail shape, fin system. It matches the right board to the right conditions at the right spot. Stop second-guessing your quiver.
🏄
Board matching
AI matches board to spot + conditions. Hollow Famara? High-rocker shortboard. Mushy Sa Ràpita? Groveller.
🔱
Fin intelligence
Pivot vs drive vs flex. Thruster vs quad. The right fin changes everything. OceanLog tracks what worked where.
📐
Hydrodynamics
Rocker, concave, tail shape — all linked to OMBE Lines. Know WHY your board works, not just that it does.
What you get
Everything you need
to surf better.
📓Session logging — 2 minutes
Spot, board, fins, conditions, wave count, what you learnt, what went wrong. 2 minutes after a session. Your watch + Strava fill in the data automatically — any watch that syncs to Strava (Garmin, Apple Watch, Coros…).
LIVE
🤖AI session reports
Weekly reports powered by Claude Opus — Anthropic's best AI. Board analysis, wave speed trends, patterns to notice, questions to bring to your next session. Surfaces what happened — you and your coach decide what it means.
COACHED TIER
🌳Skills progression tree
120 surf skills tracked per board type — Surf Simply's Tree of Knowledge, in addition to OMBE Lines 1-4. See exactly where you are, what to unlock next, and how you've improved month by month.
LIVE
⚡Watch + Strava integration
Per-wave speed, heart rate, GPS and distance from any watch that syncs to Strava (Garmin, Apple Watch, Coros, Suunto…). Where your watch reports a wave count (e.g. Garmin surf mode) it imports automatically; otherwise you tap it in seconds. Import 8 years of sessions in one click.
LIVE
🌊Weather auto-fetch
Wind, swell, wave height, water temp — auto-populated for your session spot via Stormglass. Log the session. We handle the conditions data.
LIVE
🌅First light & last light
Sunrise, sunset and the civil-twilight glow either side — your whole window of light on the water, where you ride. We even account for the headland that delays your real sunrise, not just the flat horizon.
LIVE
🏄OMBE lines + coaching
The full OMBE framework built in. Lines 1-4, skill assessment, drill recommendations. The same system coaches use — in your pocket.
LIVE
What you get
Real value.
Every session counts.
Every session you log compounds — sharper board calls, faster progression, and a record of your surfing life that's yours to keep.
Session memory
Every wave, board and condition captured — the patterns you'd otherwise forget, building session after session.
Equipment decisions
Quiver intelligence means fewer wrong-board days and more of the good ones.
Faster progression
Seeing what's actually working — conditions, gear, the sessions that click — helps you spend your water time more deliberately. Many riders progress faster when the patterns are in front of them.
