Forecast limitations
The rating covers surge and entry conditions only.
- Visibility Plankton, runoff and water stirred up for days after big seas aren't in the rating. A "Vis likely poor" note only warns when a known cause is present; it never promises clear water.
- Depth On long-period days, surge on deeper reefs is stronger than at the entry.
- On the day Sets, kelp and currents vary; look at the water before you go in.
- Further out Accuracy drops the further out you look; days 6 and 7 are a rough guide.
- This site Few dive reports to check its rating against yet.

About this dive site
The diving
Sand and rock near the north end of the beach.
Conditions & exposure
Faces west and takes swell from about 236 to 317 degrees; Point Lobos blocks the south and Cypress Point the north. Steep, like Monastery, with tight thresholds.
Hazards & considerations
For experienced divers: steep beach entry like Monastery.
Advanced forecast & data
This site's forecast combines offshore wave data, predicted ocean conditions, and Carmel River Beach's exposure to incoming swell.
Show the data and method
Buoy 46239, Point Sur: last 48 hours
Swell trains now (buoy 46239 spectrum, 3:00 PM): 5.1 ft at 15 s from 305° (NW) · wind waves 3.9 ft at 11 s. The rating still uses the buoy's single swell and wind-wave split; the full spectrum is being compared against it.
Forecast vs. buoy 46239
The raw GFS-Wave forecast is running about 2.1 ft low at buoy 46239 today (last 24 hours). The SurgeCast forecast corrects for it.

For comparison, the NWS marine grid ran 1.9 ft low over the same 24 hours. Low means the forecast was smaller than what the buoy measured; high means bigger.
Download the forecast-vs-buoy data (CSV) · NOAA's own spot-check (a handful of NOAA forecasts against this buoy; heights in meters; posted Tue, Oct 13)
Forecast check: The wave model is scaled by 1.40 at the Point Sur buoy (a starting estimate until 7 days of readings are logged). After that, over the last 36 hours the forecast has matched the Point Sur buoy well (69 readings compared).
Validation: Validation in progress: 69 forecast-and-buoy pairs so far since Tue, Oct 13. Accuracy numbers appear here once there are 100 pairs over at least 3 days.
Buoy split now: swell 6.9 ft at 15 s from the W, 40% reaches this site.

Forecast models
Waves from the NOAA GFS-Wave (WAVEWATCH III) model, run 18Z Wed, Oct 14 at buoy 46239, corrected against what that buoy has measured (systematic factor 1.40, seeded until 7 days of data are logged). The rating uses each hour's waves, wind and tide. Wind and air temperature come from the NWS forecast for the water off Carmel River Beach, issued Wed, Oct 14, 1:26 PM PDT.
NWS marine forecast: Point Pinos to Point Piedras Blancas, out to 10 nm
Tonight: NW wind 10 to 15 kt, easing to 5 to 10 kt late this evening and overnight. Seas 4 to 5 ft. Wave Detail: NW 4 ft at 8 seconds and SW 3 ft at 15 seconds.
Thu: NW wind 5 to 10 kt. Seas 4 to 5 ft. Wave Detail: NW 4 ft at 7 seconds and SW 3 ft at 15 seconds.

Rating logic
- Surge
- The rating turns each swell into a "surge index" in feet: the height that reaches this site, weighted up for longer periods because long swell moves the water harder near the bottom. Here the index moves from Great to Good at 1.8, Fair at 2.3, Rough at 2.7 and Severe at 3.2 ft. Right now it is 3.4 ft.
- Direction
- Faces west and takes swell from about 236 to 317 degrees; Point Lobos blocks the south and Cypress Point the north. Steep, like Monastery, with tight thresholds.
- Wind
- Onshore wind here blows from the W. Onshore wind over about 10 kt chops up entries and surface swims; a strong offshore wind (over 15 kt) pushes surface swimmers out. Gusts count for half.
- Tide
- Heights at the Monterey tide station, in feet above mean lower low water. The entry is easiest between -0.5 and 5.5 ft; tide only nudges the rating.
- Trend and confidence
- The trend compares the last 9 hours at the buoy with the next 12 hours of forecast; a building long-period swell can push a borderline day one step worse. Confidence is High for a fresh buoy reading or a forecast for the next 12 hours, and drops with lead time, a backup buoy, or a forecast that has been missing the buoy.
- Limits
- A model, not a guarantee. Back-tested on 137 dated diver reports, it matched the reported level 72% of the time and was within one level 96% of the time (tuned on those same reports, so expect a little less). Always look before you go in.
