Tide Clock

How the Quiver tide clock works

Search any beach to see the current tide height, next high and low times, and a 24-hour tide curve. The display adjusts automatically for each beach's local timezone.

Predictions come from NOAA — the same source used by the Coast Guard and National Weather Service. Typically accurate within 5-10 minutes and a few inches for US coastlines.

Most US beaches see two highs and two lows per day, roughly 6 hours apart. The transition between them — when the water is moving fastest — often produces the best conditions for surfing.

Use the tide clock with the 7-day surf forecast, water temperature guide, and surf map to decide whether a tide window is actually worth paddling out. For a city-level starting point, check San Diego tide charts or browse San Diego beach pages.

Frequently asked questions

What time is high tide today?
Search for your beach above — the clock shows the exact time and height of the next high and low tide.
How accurate are tide predictions?
NOAA predictions are typically accurate within 5-10 minutes and a few inches for US coastlines. Strong storms or unusual weather can shift actual times by more.
What is the best tide for surfing?
It depends on the break. Beach breaks often work best at mid-tide, while reef breaks tend to prefer low to mid tide. Check the full forecast for your beach's ideal conditions.
What does a rising vs falling tide mean for surfing?
A rising (incoming) tide adds depth — good for some breaks, too deep for others. A falling (outgoing) tide exposes reef and can make waves more hollow. The first hour or two of either change, when water moves fastest, often produces the best surf.
