Source and percentage

The large percentage runs from this tide’s low (0%) to its high (100%). The live waterline follows predicted height in metres. Preview 0% restores the original low-water photograph; 100% shows the highest prediction in the surrounding 35 days. The photograph’s tide and shore elevations are estimated.

Photo geometry and visualization

Visualization

Estimated

The photograph is treated as low tide. Water rises against estimated 3-D beach, wall and rock surfaces. Its capture tide, camera geometry and beach levels are unknown, so the contact line and underwater depths are visual estimates.

Dunnycove’s shelter influences the rendered chop and foam. The wind and offshore wave values remain the original forecast values. Local breaking, run-up and currents need bathymetry and are not measured here.

Pressure, wind and waves are displayed independently. No unverified surge or pressure correction is added to the tide height.

Mapped coast

Photo markers follow their declared location. Tap the map to mark where the camera stood; your phone location is separate. The mapped coast represents high-water shoreline, not the current waterline.

Calibrate this photograph

Automatic depth proposes the shore shape. Set a known camera height and photograph water level to give it a metre scale. Corrections are saved for this exact viewpoint.

Tap around the photographed sea to trace a polygon. Include near and distant water; keep sand and foreground rocks outside it. At least three points.

Daylight views with the sea above the shore are preferred.
