Station, reference level & prediction method

MIO-CIMAR Bahía Herradura station 40 · 23.0 km from Esterillos Oeste · regional tide reference; local timing and height may differ · 40

Reference level: MIO mean-low-tide reference.

The chart and matching times use linear interpolation between predicted extrema. Heights between events are approximate. Gaps and unbracketed times have no estimate.

Source time: Oct 16, 11:51 AM CST.

The assigned station describes regional water levels. Local beach waterlines, currents, crossings, and access require separate information.

About this spot

Model-grid forecast requested at the mapped coordinate; reef, headland, and nearshore transformations are unresolved. Beach break. Esterillos Oeste beach break; this route covers the western section of Esterillos only. Published map coordinate is approximate; coastline orientation and breaking-surf response are uncalibrated.

Mapped spot coordinate: 9.5281, -84.4903.

Mainland Costa Rica · Pacific · Coastline orientation unresolved · Location provenance

Model request point: Esterillos Oeste (9.5281, -84.4903). Model output times describe valid conditions; the provider does not expose the model run issue time in this response.

Data coverage 3/7 sources

Source availability is not forecast accuracy. Where an empirical model passes historical testing, its error and interval coverage are shown above. Source count cannot increase that confidence.

How best guesses are made

Best guesses combine usable wave and wind evidence, with qualitative confidence and specific limitations. A missing tide or local surf-height model does not prevent useful guidance. Tide levels use the named station datum; their effect at this break remains uncertain. Wind direction is relative to the mapped beach orientation, without calibrated terrain or shelter effects. The comparison is a heuristic, not a measured quality rating.
