Reñaca surf forecast and swell data

Reñaca is a beachbreak on the central Chilean coast where the same offshore swell can look very different depending on direction, wind, tide and sandbars.

Which data to check

Use the Valparaiso coast model for offshore height, primary swell period and direction. It is a marine model estimate, not a physical buoy reading.

Pair that signal with local wind, tide and a live camera or beach observation before deciding whether the beach is working.

How exposure changes the result

Southwest and west-southwest energy can reach this stretch of coast, but local orientation and coastal shelter can reduce the size seen at the beach.

A longer period can bring more energy than a similar-height short-period reading, while onshore wind can quickly degrade conditions.

Reference tides

Check predicted high- and low-tide times for the reference port station.

Practical takeaway

For Reñaca, treat the model as offshore context and confirm the beach itself with wind, tide and a current visual check.
