Table - best surf conditions forecast for Geriba over the next 16 days.
Alright, Rusty here. Let’s break it down.
The first few days are a bit flat and messy, but there’s a couple of clean windows later that are worth pointing out. Geriba is the only break in the mix, so that’s where we’re at.
The water temp is about normal for this time of year. Sunday the 12th is a no-go – tiny, onshore, and just ugly. Monday the 13th sees a pulse of energy, with a combined swell energy of 1039 (moderate) and waves around 8ft, but a fresh cross-onshore wind makes it lumpy and poor.
Tuesday the 14th stays messy – 7ft to 8ft of S to SSE swell, but with strong onshore winds giving us choppy, marginal conditions. The energy gets up to 2182 (strong) on Tuesday afternoon, but the quality is poor.
Now, Wednesday morning the 15th is the first real window. You’ve got a clean 7ft SSE swell with an 11-second period and a light offshore wind from the NNE. That’s glassy, clean surf, and the combined energy is 982 (moderate). This is your standout for the first week – light wind, clean lines, and a decent size. Get out there if you can.
Thursday the 16th holds similar size (7ft SE) with a fresh offshore wind, but it’s stronger, making the paddle a bit tougher. Still clean. Friday the 17th and Saturday the 18th see the swell drop fast, with strong wind, so not worth the effort.
Then we hit a quiet stretch. From Sunday the 19th through Friday the 24th, the swell goes tiny – 0.7ft to 2ft. Combined energy drops under 200 (weak). There’s a long-period S groundswell on the 20th and 21st (periods up to 18 seconds), but at only 0.7ft to 1ft, it’s a flat spell. That’s about a week of nothing much.
But then, Saturday the 26th is a real standout. Clean 5ft S swell with a 13-second period and a moderate offshore wind from the NE. The combined energy jumps to 1130 (strong). This is marked as excellent for experienced surfers – powerful, clean, and the offshore breeze will have the waves lined up. That’s your big one for the second week.
Monday the 27th keeps it going: 5ft S swell at 14 seconds, with a light offshore wind. Clean, glassy, combined energy of 721 (moderate). Another very good session.
So, bottom line: Wednesday morning the 15th is your first solid chance. After a flat week, Saturday the 26th and Monday the 27th look like the best of the whole run – strong groundswell, offshore winds, and clean waves. Long-range is promising but not locked in yet.
Stay stoked.
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.
