Nanwan surf guide

Nanwan is the main beach for Hengchun, located on the southeastern coast of Taiwan. This spot has become popular among surfers due to its unique waves and scenic backdrop. The beach faces southeast and is known for its vibrant atmosphere, drawing in both locals and tourists. It's a pretty solid spot, especially for those looking to enjoy some surf away from the usual crowded beaches.

The surf at Nanwan really shines with a southeast swell, and it handles waves in the range of about 2ft to head high (0.6m to 3m). The right reefbreak is what many come here for, offering nice curves and a clean face on low to mid tides. If conditions align just right with a solid typhoon swell, you can find some decent barrels. However, it’s generally suited for intermediate surfers who can navigate the uneven reef and varying wave types. On bigger days, it's essential to be careful of the coral and to keep an eye on the swell direction, which can also come from the southwest.

Besides Nanwan, there are other spots in the area that can provide different wave experiences, like the shallow rights and lefts at Houbihu Harbour or the long, hollow rights further out at Houbihu Point. If you're looking for a change of scenery, you can find more beach breaks scattered along the east towards the resort beaches of Kenting, especially when a south swell is running. For the best results, a northwest wind is preferable, so keep that in mind as you plan your sessions.

Wind certainty

Wind certainty tells you how much the weather models agree on the forecast.

  • High certainty: Models agree closely; forecast is reliable.
  • Medium certainty: Some disagreement; conditions may shift slightly.
  • Low certainty: Models diverge; treat forecast with caution.

We calculate this by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.

Forecast Cheat Sheet

Short on time? Focus on wave energy. It’s the best single metric to gauge how big and powerful the waves will be.

Click any table cell to jump to that forecast hour. The map will update with forecast arrows, so you can see if wind and swell direction are lining up.

Use the table sidebar to switch units for height and speed.

Log your surf sessions to compare forecasts with real sessions and sharpen future predictions.

On the map, click a metric label to bring that arrow to the front — handy when arrows overlap.

Models and Updates

Surfnerd blends multiple global and local wind and swell models using advanced interpolation and spatial techniques to create an "ensemble" forecast. Forecasts are refreshed hourly.

Surf Predictions

Our AI-driven algorithm scores surf quality, shown by green, orange, and gray dots. Each forecast hour is rated for wind, swell, and tide quality, then combined into an overall score. Here’s the scale:

Perfect
Good
Average
Bad or No Data

Session logs also feed the algorithm — the more you log, the smarter your forecasts get.

With Surfnerd, no more "you should have been here yesterday"
