Local knowledge

Honoli'i is Hilo's daily wave — a rivermouth that catches wrap from both NE trade swell and winter north energy, framed in green cliffs. It's the Big Island's community lineup: groms after school, uncles at dawn, and a wave that almost never fully disappears.

FAQ

What swell direction works best at Honoli'i (Hilo)?

ENE swell hits Honoli'i (Hilo) straight on. The spot picks up anything arriving from N (0°) through SE (130°); swell from outside that window is blocked by the coastline.

What wind is best at Honoli'i (Hilo)?

WSW wind blows offshore and grooms the surf. ENE wind is straight onshore and chops it up; light wind under ~5 kn is fine from any direction.

When is the best time of year to surf Honoli'i (Hilo)?

Winter (October-March), when North Pacific storms send the legendary N/NW groundswell. Summer is small to flat on this shore.

What's the best tide at Honoli'i (Hilo)?

Mid. Tide predictions for the spot's NOAA station are in the forecast above.

Is Honoli'i (Hilo) good for beginners?

Yes on ordinary days — it's where Hilo learns; bigger east swells add push and current.

How warm is the water at Honoli'i (Hilo)?

Roughly 74°F at its late-winter coldest to about 81°F in late summer. In practice that means trunks or a rash guard in winter and trunks or a rash guard in summer. The forecast above shows the current water temperature.

How far out is this forecast reliable?

The wave model has real skill to about 10 days, and we cut the chart there instead of padding it with guesses. Days 1-3 are solid, 4-7 useful, 8-10 a trend heads-up - and we publish our measured error against NOAA buoys, updated continuously.
