The Lowdown
Alright folks, Rusty here. Let’s break it down. We’ve got a solid 16-day window, but the first week is a bit of a slow one. The real firecracker shows up in the second week, with a proper pulse of energy that’ll have the experienced crew grinning. For now, we’re looking at a long stretch of small, clean, but ultimately weak surf through the end of July and into the start of August. The wait is worth it, but only if you’re looking for a challenge.
The first real chance to get wet is on Sunday, July 27th, but it’s mostly a tease. We’ve got a light south swell wrapping in, around 3ft, with a period of 12 seconds. The combined energy is moderate at 548. The morning is the pick of the day with an offshore NE breeze at 12 mph, making for clean, tidy lines. Geriba is a beginner-friendly spot, and the crowd factor is often there, so you might have to share. The water temp is about normal for this time of year at 72°. Honestly, it’s surfable, but not a standout.
From Monday, July 28th, through to Sunday, August 3rd, the surf drops off significantly. We’re looking at waist-high dribble, mostly 2ft to 3ft, with weak energy readings (as low as 27). The winds are offshore most mornings, which is nice, but the swell just isn’t there. This is a gap of about a week where you’re better off doing something else. The forecast is reliable for this period, and it’s just flat.
Now, hang on to your board. The action kicks off on Wednesday, August 5th. The afternoon brings a jump in size to 7ft from the SSW, with a 15-second period. The combined energy is a solid 1925. The wind is light and cross-shore, so it’s a bit messy, but the power is there. This is a big swell for the area, and it’s only for experienced surfers. The real standout, though, is Thursday, August 6th.
Thursday, August 6th is the highlight of the whole outlook. The morning session is firing: 8ft of south swell, with a 14-second period, and a moderate offshore NE wind at 12 mph. The energy is pumping at 2179. The afternoon is even better, with 8ft of clean, powerful swell from the south, and a gentle offshore breeze at 9 mph. The energy jumps to 2521. This is a heavy, long-period groundswell, so it’s going to be a freight train. It’s going to be steep and powerful, best handled by experts. The wave quality is excellent.
Friday, August 7th morning is also a top-tier option. We’re looking at 8ft of south swell, 13-second period, and glassy conditions with a light SSW breeze. The energy is very strong at 1766. It’s a clean, powerful morning, but the afternoon turns onshore, so get it early.
Saturday, August 8th keeps the size up with 7ft from the SSE, but the wind is a bit stronger offshore in the morning. The energy is still strong at 1407. The afternoon gets blown out.
After that, the swell slowly fades from Sunday, August 9th through Monday, August 10th, dropping from 5ft back down to 3ft, with the energy dropping off too. The winds stay offshore, but the size and power are gone.
So, to wrap it up: the first week is a bust. The real show is Thursday, August 6th, with the morning and afternoon both offering excellent, powerful surf for experienced folks. The Friday, August 7th morning is a very close second for the glassy conditions. Don’t bother with the rest unless you’re desperate for a paddle. Stay safe out there.
Rusty.

Information about the Geriba Surf forecast
The above surf forecast table for Geriba provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Geriba can be found by selecting the local surf guide option on the grey menu. Our Geriba surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Geriba) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Geriba may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
