Choushui conditions today
Wave height gauge: Waist-to-chest
How to read the two heights: Hs is the model's significant wave height; metres and feet are two units for that same Hs height (1 ft = 0.3048 m). Breaking-wave face height is an engineering estimate that applies a period-aware nearshore shoaling factor to Hs, so it is usually larger. It is not a unit conversion or an on-site measurement.
Waist-to-chest, soft waves, Cross-shore wind, good for practice.

Needs ENE, E, ESE · today ENE, E, ESE ✓
The swell sits in a direction this spot works on (ENE, E, ESE), so it clears the gate.
- Period5.7s soft
Needs period over 5s · today 5.7s soft
Period is on the short side, so the shape is average.
- WindCross-shore wind 2.0m/s
Needs WSW, W (offshore) · today Cross-shore wind 2.0m/s
Onshore wind messes up the face and flattens it, but it's light.
- Wave heightWaist-to-chest · Hs 2.1ft (0.6m)
Needs Hs 1–3ft (right for your level) · today Waist-to-chest · Hs 2.1ft (0.6m)
Wave height sits in the ideal range for your level (Hs 1–3ft).
- TideRising, mid tide
Needs Low to mid · today Rising, mid tide

About Choushui

It works best on east-northeast, east, or east-southeast swell with offshore winds from the west-southwest or west on a low to mid tide. Rated upper-intermediate, so it suits surfers with solid footing rather than first-timers.

- How do I get to Choushui?
- Choushui sits on the coast in Yilan, Taiwan. Open Google Maps navigation straight from the spot map on this page to get there.
- Does Choushui have a live cam?
- Yes. This page embeds a live feed from National Academy of Marine Research at "Wushi" (about 1.1 km SW of Choushui) (not a direct view of this spot, for reference only), so you can check it against the current conditions. The camera tends to flatten waves, though, so go by this page's verdict for the actual call.
