Yonabaru Surf Forecast and Surf Report

Alright, Rusty here. Let's have a look at what's on the cards for Yonabaru over the next couple of weeks.

Straight up, the outlook is pretty grim. The first six or seven days are basically a write-off, with no good surf on offer. The water temp is sitting at a standard 84°, which is spot on for this time of year, so nothing weird going on there.

We kick off on Friday the 21st with a tiny 0.4m swell from the ENE, but it’s got a short 8-second period and a storm risk with a 25-30 km/h cross-onshore breeze. It’s just a mess. Saturday the 22nd is even smaller. Sunday the 23rd sees a bump in size to 1.1m, but the period drops to a shocking 5 seconds, making it choppy and weak with a combined energy of only 118 – genuinely poor. Monday the 24th changes things up: we get a proper 1.8m groundswell from the ESE with a very long 17-second period, giving a solid combined energy of 2009. The problem is a direct onshore wind (E at 25 km/h) and the model says the surf conditions are poor. Tuesday the 25th is the big one, with a huge 3.5m swell from the ESE, but the forecast literally tells us it's too big for this break. That’s expert-only territory and even then, the wind is cross-onshore, making it choppy. Wednesday morning the 26th is the first glimmer of hope—a clean 1.3m swell from the NNE with a gentle offshore breeze from the WSW, and the model calls it "very good surf conditions." The period is a nice 11 seconds, so there's some real shape there. It’s a standout for the entire forecast but it's been downgraded by the scale of the rating, so don't get too hyped.

Then we’re back into a long, dry gap. From Wednesday afternoon through to Friday the 28th, the swell drops right off and we get hammered by strong offshore winds (35-50 km/h) that make it impossible to paddle into anything. Saturday the 29th and Sunday the 30th are cross-shore junk. All the way through to Friday the 4th of September, the energy stays weak or moderate, with the biggest size being around 1.0m to 1.4m and mostly cross-onshore or onshore winds. It's a bleak run of poor or marginal conditions.

Then, nearly two weeks away, on Saturday the 5th of September, we finally get something worth waiting for. A 1.5m swell from the East with a 14-second period and a combined energy of 855—and the wind goes glassy. The model gives this a fair rating for "very good surf conditions." That’s the one to circle on the calendar. Sunday the 5th afternoon is also clean with a light cross-offshore breeze. For a spot that’s fairly consistent, this is a long stretch of nothing, but the glassy weekend at the end looks promising for a session. For Yonabaru, which is a beginner-friendly, fairly exposed break, this is a tough run.
