Plan around the wind

The best available upcoming daylight wind sample to compare with the wave evidence. This compares wind only; wave size, tide suitability, and hazards can change your choice.

  • 3:00 PM–5:00 PM · America/Costa_Rica

    Light wind · up to 4.7 kt · reported gusts up to 12.6 kt

    Offshore waves: 4.2–4.3 ft across the period. Surf height unavailable. Tide data available; check the local tide response.

    Wind source time: Oct 16, 10:00 AM CST. This is not the model run issue time.
How these periods are chosen

The planner prefers three consecutive hourly samples covering two daylight hours, but retains shorter one- or two-sample evidence when that is all the forecast provides. Light wind means at most 6 kt. Moderate offshore means at most 12 kt from land toward the sea when shore orientation is verified. Strong wind or known gusts of 20 kt or more remain visible as cautions instead of making the entire comparison disappear. These are comparison labels, not locally tested surf-quality or safety ratings. Missing gusts remain unknown. Terrain shelter, currents, closures, and your ability are not assessed.

Forecast confidence
  • Returned marine grid point is 8.5 km from the mapped spot. Provider grid resolution is not established for this response.
  • Reference model hour: 0 hours from now; historical residuals do not measure forecast lead-time error.
  • No accepted local model for these inputs: missing history, unsupported direction/period/height, or failed historical validation.
  • A mapped coordinate does not establish nearshore grid resolution or terrain/shelter accuracy.

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, 10:08 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.

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.
