Better forecasts. Better sessions.
Data-driven surf predictions for the UK coastline.
Our Mission
MysticSwell exists to help UK surfers make better decisions. Whether you're checking conditions before the drive down or planning a week of sessions, we give you the data you need — clearly, quickly, and without the clutter.
We cover 36 spots across 11 regions, from the north coast of Scotland to the south coast of England, and we're adding new spots all the time. Every forecast is free, with no account required.
What You Get
7-day forecasts
Detailed hour-by-hour forecasts including surf height, swell period and direction, wind speed and gusts, sea surface temperature, and weather conditions — updated multiple times a day.
Quality ratings
Every time slot is scored from Poor to Epic based on wave height, swell period, wind direction, swell alignment, and tide. No guesswork — just clear ratings that tell you when it's worth paddling out.
Best time to surf
We identify the optimal windows each day based on the combination of swell, wind, and tide — so you can plan your session around the best conditions.

The Mystic Forecast Model
Most surf forecasts rely on a single global weather model. Mystic goes further — blending global and high-resolution regional ocean models into a single, optimised prediction calibrated to what you'll actually see in the water.
Multi-source blending
- Global swell tracking across ocean basins
- 3km regional model for nearshore detail
- Time-weighted blending algorithm
- Swell fraction analysis (clean swell vs wind chop)
AI quality scoring
- Surf height as realistic ranges, not raw model output
- Conditions rated from Poor to Epic
- Wind scored relative to each beach's orientation
- AI-generated plain-language surf summaries
