Off The Wall Surf Forecast and Surf Report

G'day, it's Rusty here. Let's talk about what's out there. This run has a few proper sessions and some periods you’ll want to sleep through. We’re looking at a shift from clean, powerful surf to a few days of onshore junk and then a final blast of serious size.

Wednesday morning kicks us off with a clean 8ft of southwest swell at Off The Wall (Big Island). The energy is moderate at 1866, with a 12-second period. It's a reef setup, so it's only for the sharp ones, but that cross-off breeze is keeping the surface nice. It's not massive, but it's a clean start. The afternoon keeps the vibe similar with 8ft. The water temp is about normal for this time of year.

Now, Thursday the 20th morning is one of the best calls of this whole window. The swell jumps to a strong 10ft from the southwest with a longer 13-second period, and the energy is firmly in the strong category at 3422. With a light cross-off wind, it's going to be pristine. This is a proper, powerful, advanced wave. The lineup might have a few regulars out, as crowds are possible.

Friday pulls back to a still-fun 7ft in the morning, but the period drops to 11 seconds. It's a step down from Thursday's glory. The afternoon is smaller again, at 5ft.

Saturday the 22nd is a total dud for surfers. The morning is weak at 3ft and messy, and the afternoon is blown out with a northerly wind. The best you could say is it might be okay for kites. Sunday the 23rd brings the size and power back with a 10ft WSW swell at a 13-second period; it's clean, but it's a handful.

Monday the 24th settles down to 5ft. It’s fine, but forgettable. Tuesday the 25th is the other standout of the week. A 8ft southwest swell with a long 14-second period arrives, and we score a proper offshore wind out of the southeast. It's going to be glassy perfection. The energy is strong at 2050. This is a day to call in sick for.

The middle of the week gets junky. Wednesday the 26th and Thursday the 27th are small and bumpy with onshore breezes, in the 4ft to 6ft range. Not worth the paddle.

The ocean wakes up again on Friday the 28th with a solid 8ft, and then Saturday the 29th is the big one. The swell holds at 10ft, the winds clock offshore, and the energy is pumping at 3978. This is heavy, powerful surf. Sunday the 30th is a wild, stormy affair. There's still 10ft of swell, but a near-gale offshore wind at 50 km/h will make it nearly impossible to get out.

The start of September has some long-period swells, but the onshore winds are going to ruin the quality. And the final day, Thursday the 3rd, is a legit giant. We're talking 20ft of swell with a 14-second period and an energy reading of 24296. That's a life-threatening amount of water. Only the most crazy are even thinking about that.

So, for the best combination of size, clean conditions, and overall quality, mark Thursday the 20th and Tuesday the 25th. The 29th has the size but it's a battle. The 3rd is for the specialists.

Rusty.
