▶ Cal Coast Tides

Predictable water. Safer trips. Better days.

Tides, swell and wind for the California coast, in plain English.

The problem

Planning a day on the coast means five tabs and a guess.

Tides on one site, swell on another, wind on a third, buoys in raw text files. None of them answer the real question: is it a good time to go?

The answer

One page for your stretch of coast, with the answer first.

Every station opens with one plain sentence about the tide, so you know what the water is doing before a single chart loads.

When to go

See the best windows at a glance

A 72-hour timeline lines up tide, wind and swell, then marks the best hours for each activity.

Prediction vs. reality

The tide table, checked against the real water

Live sensors measure the water every six minutes. When wind or air pressure holds the sea above or below the prediction, you see the gap.

Swell alert

Know when a big swell is on its way

An offshore buoy feels a new northwest swell hours before it reaches the beach. For Port San Luis, the site spots it and gives a likely arrival window.

Buoy check

Real waves vs. the forecast

Each nearby buoy's measured waves are compared with the forecast for the same spot over the last six hours, so you know if the ocean is running bigger or smaller.

Surf spots

A 7-day forecast for each break

Ten named Central Coast spots get their own wave size, wind and tide read, graded hour by hour. Surfers report how it really was, and those reports tune the size.
