Trespassers Surf Forecast and Surf Report

Grab your board, it’s a mixed bag out there for the next couple of weeks, but there are a couple of legit windows that’ll make it worth paddling out for. Let’s break it down.

Trespassers (Big Island)
Right off the bat, Monday the 14th is a write-off. It’s messy and weak, with a SW swell around 0.8m and onshore WSW wind at 15 km/h. Not your day. Tuesday the 15th picks up a bit with 1.8m of SW swell, but the S wind keeps it choppy, and the tide doesn’t help—it’s only a so-so session.

Wednesday the 16th is where it starts to feel alive. Still 1.7m of SSW swell, but the ESE wind is offshore and it’s clean. That’s your first real look. The energy is moderate (1238), and the swell period is 15 seconds, so it’s got some push. Thursday the 17th drops back a little, but the glassy afternoon with 0.9m and no wind is worth a sneaky session if you’re free. Friday the 18th and Saturday the 19th are pretty grim again—weak, short-period junk and cross winds kill it.

Now, the big one: Monday the 21st. The afternoon is the standout of the whole run. We’ve got 2.0m of SSW swell at 16 seconds, and it’s absolutely glassy with a 5 km/h WNW breeze. The energy reads 2324—that’s strong, and it’s the kind of clean, powerful, long-period groundswell that’s going to reel down the reef. It’s got excellent conditions for experienced surfers. This is your best bet, no question. But listen: 2.0m with that period is not for beginners. If you’re not confident, watch from the rocks. There’s a downgrade in the morning, but the afternoon is where it’s at.

Sunday the 22nd holds around 1.5m but the wind goes onshore in the afternoon, so it’s a morning window if you’re keen. Monday the 22nd is rocky, Tuesday the 23rd is poor with fresh cross-onshore winds, and the rest of that week stays average—some shoulder-high slop, but nothing to get excited about.

Then we get the finisher. Saturday the 26th morning is clean with 1.6m of SW swell and light E offshore wind, energy at 1221, good conditions. And then Sunday the 27th is the other true standout—1.9m of SSW swell at 20 seconds, that’s long-period and powerful. The energy is huge at 2759, and with a gentle NE cross-offshore breeze and clean skies, it’s excellent for experienced surfers. Break has that long-period push that will really work the reef. Just keep in mind, 20 seconds is getting into that territory where it can bend a bit straight on certain spots, but here it’ll be fine.

Monday the 28th and Tuesday the 29th wind down with less energy and onshore winds, so the tail end of the window is weaker.

Water temp is pretty normal for this time of year, nothing crazy—just your usual tropical warmth, so no need for a thick wetsuit.

Crowds at Trespassers can be a bit of a thing sometimes, especially when the surf is good, so expect some company on the peak during the standout days.

All in all, your two must-do sessions are the 21st afternoon and the 27th. Everything else is either too small, too choppy, or just plain messy. Don’t waste your energy chasing the rest.
