Impossibles surf forecast guide

Impossibles is a surf spot located near Padang Padang, Bali. Known for its long coral reef, it becomes a popular destination for surfers when the right swell comes in. The spot is best accessed at low tide to avoid the sharp reef, and while it can look perfect from above, it offers some challenging conditions that can catch you off guard. Crowds here are generally manageable, making it a good option for those looking to avoid the busier spots nearby.

This break generally loves a moderate to large, long period south swell, which rolls in nicely from the south and southwest. It handles swell sizes up to about 4 ft (1.2 m) well. The waves here are predominantly reef breaks, breaking left, and can get really fast, especially in certain sections. Low tide is the sweet spot for getting into those barrel sections, while high tide can get a bit choppy. If you're not at least an expert surfer, it might be a struggle to navigate the quick waves and the layout of the reef, which has some straight bits that can catch you off guard.

For the best experience, southeast winds work in your favor. The paddle-out is similar to Padang, so be prepared for a bit of a session to get out there. It's a good idea to wear booties when getting in and out over the low tide reef to protect your feet. Overall, the spot offers a unique surfing experience that can be rewarding for those who know how to handle it.

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 youโ€™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:

๐Ÿ”ฎ 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.

๐Ÿ’จ Wind section

The first row on the table (with the ๐Ÿ’จ icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

๐ŸŒŠ 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.

๐ŸŒ’ 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 โ€” handy when arrows overlap.

Forecast Cheat Sheet

Short on time? Focus on wave energy. Itโ€™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. Hereโ€™s the scale:

Perfect
Good
Average
Bad or No Data

Session logs also feed the algorithm โ€” the more you log, the smarter your forecasts get.

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