Stronger sea-state signal
A strong sea-state signal: waves and spray may affect sea-level climbing. Higher modelled water around 18:00 coincides with a raised sea-state signal. Check official tide times.
Saturday 10 October · 08:00 to 18:35 local time
From 08:00 or sunrise, whichever is later, until sunset. Tide-related turns below cover the full calendar day.
Offshore waves
1.9 to 2.3 mSignificant wave height, not the largest individual wave.
Swell
0.8 to 1.4 mPeriod 7.7 to 8.4 seconds. Longer-period swell can matter even in light wind.
Coastal wind
17.4 to 24.4 mphGusts 28 to 38.9 mph. Model 10 m open-ground wind, not face or belay wind.
Rain and temperature
0.1 mm12.8 to 14.3°C. Rain covers source hours overlapping the daytime window.
Coast and spray
Stronger spray signal
- A notable offshore sea state is forecast.
- Waves approach the broad coast-facing direction.
- Swell approaches the broad coast-facing direction.
- Onshore wind may carry spray inland.
A broad westerly marine exposure represents the headland. Baggy Point has differently oriented sectors, so route-level wind shelter and direct sun are not resolved.
Spray is an uncalibrated indication, not a probability or a height prediction. A lee wind does not establish shelter from swell.
Predicted astronomical tides
Calculated every five minutes from harmonic constants fitted to the nearby tide gauge's measured record. Some locations can have genuine secondary highs and lows.

Ilfracombe tide gauge, about 13 km from the crag. Local timing, surge and wave reach at Baggy Point can differ. Times are predictions, not observations at the crag. Heights are deliberately omitted because they are not tied to a climbing ledge or chart datum here.
Total water-level model
Approximate peaks and dips in total sea level, including tide and weather effects. Source resolution is hourly, not a guarantee of timing accuracy.

- Model level peakAbout 18:00
The total-water heights use mean sea level, not chart datum. Do not compare them directly with guidebook tidal-access heights.
Different parts of the crag
Sea-facing cliffs and starts
The position of individual starts above the water is not calibrated. Use a current guide and inspect the sea before committing.
Upper cliff and top-outs
Upper rock may be less affected by direct wave reach, but wind, spray and retreat conditions still matter.
How conditions change through the day
Directions show where wind and waves approach from, relative to the provisional broad coast aspect, not a surveyed climbing face.

How this preview works and what is missing
Astronomical tides use 50 harmonic constituents from TICON-4, fitted to many years of measured tide-gauge data. The Moon and Sun are represented through these astronomical constituents, while local coastal shape is learned from the gauge record. Wind and pressure are not added to that curve.
Separately, we combine Open-Meteo waves, swell and total sea-level forecasts with local weather and a provisional coast-facing direction. Larger waves, longer periods and waves approaching the coast strengthen the sea-state signal. Onshore wind strengthens the spray signal. These are transparent research rules, not calibrated predictions of wave reach.
We do not add swell to total wave height because total waves already include swell. We also keep the astronomical tide and weather-affected total-water model separate to avoid counting surge twice.
- Offshore model guidance, not conditions at a particular ledge. Individual waves can exceed the quoted significant height. Check official tide tables, route access and the sea on arrival; no safe-access window is calculated.
- Spray signals are provisional rules, not calibrated probabilities or spray-height predictions.
- The pilot does not resolve bathymetry, wave refraction, reflected waves, surge residuals separately or salt deposits on holds.
- A sheltered wind direction does not establish shelter from swell. Offshore direction never establishes safe access.
No climbing score, safe-access interval or notification is produced. These crags are excluded from live rankings. Rock type is descriptive here; salt, seepage and drying are not yet modelled for this pilot.
Returned marine grid centre: 51.1, -4.4. Small coves, headlands and ledges are not resolved.
