Holywell Bay surf guide

Holywell Bay is a scenic, crescent-shaped beach located in a quiet area that offers a chill vibe away from the busier spots like Newquay. The beach is backed by sand dunes and requires about a ten-minute walk from the National Trust car park in the village to get to the shore. This spot is often overlooked, making it a great option if you're looking to escape the crowds and enjoy some time in the water.

The surf here can be a bit hit or miss. When conditions are right, you can find fun beach breaks with lefts and rights, but there's also the chance of hitting long closeouts. The best conditions typically come with clean swells rolling in from the west (W), handling sizes from about 0.6m to 2.4m (2ft to 8ft). The optimal swell direction is from the west, and it can also work with southwest and northwest swells. It’s more workable at low to mid tide, but be mindful that rip currents can develop when the swell picks up. If you’re a beginner or intermediate surfer, this spot is suitable for you. Bring your shortboard, fish, funboard, longboard, or bodyboard, depending on your skill level and the size of the waves.

While the beach generally offers easy paddling when it's smaller, larger swells can create some rippy conditions. The preferred winds come from the southeast (SE) for the best surf experience. The season for catching good waves here is from September to February, especially when the swell is cleaner and bigger. Overall, it's a bit of a roll of the dice—sometimes you score a great session, and other times you may find yourself in a frustrating close-out.

Confidence

Confidence tells you how much the weather models agree on the forecast.

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

We calculate the wind confidence by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. For wave certainty we compare height, period and direction, also on multiple models. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.

Readme

Welcome! If you’re new to surf forecasting, check out this quick guide.

Forecast Table

The forecast table (the section on the page with all the numbers) is designed to pack as much information in the screen as possible. Although intimidating at first, it will help you make informed decisions about the waves faster, trust me :D. The table consists of roughly four sections, time and predictions, wind, waves, and tides:

🔮 Time and predictions section

Here we show the forecast thour and the overall surf quality prediction. This is determined based on the wave, wind and tide quality prediction. These individual predictions can be found on the forecast map.

💨 Wind section

The first row on the table (with the 💨 icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

🌊 Wave section

The waves section consists of three rows, one for wave height and direction, one for period and one for wave energy. Our algorithm choices the "dominant wave". This is normally the first swell partition, but with heavy local storms it displays the wind waves. If that's the case, we display the numbers in italic and in gray.

🌒 Tide section

The tide section consists of a row with the actual heights per hour (measured at the half hour) and a table that displays the flow of the tide and the extremes (lows and highs).

Forecast map

The forecast map consists of arrows. These arrows represent all wave partitions (swell partitions and wind wave partition) and the wind. This allows you to see things like: a secondary swell or wind waves messes up the surf, or the wind is just a tick offshore so very surfable. Click a metric label in the bottom left to bring that arrow to the front — handy when arrows overlap.

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.

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.
