The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Geriba. We’ve got a bit of a slow start, so don’t rush to check the waves just yet. The first few days are a write-off with tiny, gutless swell and some messy wind. That changes on the morning of Thursday the 3rd of September, when we finally see some life.
Thursday the 3rd of September is the standout window. The morning is looking magic with a clean 5ft swell pushing in from the S, a solid 11-second period, and a gentle offshore wind from the NE. The water is sitting at 72°, which is about average for this time of year. The combined energy is moderate (617), and the winds are glassy and clean. This is your best bet for a proper session. The afternoon holds up with a similar swell, but the wind picks up to a fresh 21 mph cross-offshore, staying clean but a bit more challenging.
The Friday morning of the 4th is still worth a paddle, with 4ft of S swell and a fresh offshore wind from the NNE. Energy is moderate (273). The swell period is still 11 seconds, so the waves will have some shape and power. After that, the surf drops off again through the weekend into a stretch of smaller, weaker, and wind-affected waves.
There’s a gap of a few days with no real standouts until we get to Tuesday the 8th of September. The swell builds again, but the wind is a messy cross-shore, and the waves are over 5ft, bumpy, and not well shaped. This is more of a kite session than a surf session, honestly. The combined energy is strong (1094 in the morning, 1412 in the afternoon), but the quality just isn’t there for a paddle.
Friday the 11th of September morning could be a sneaky one, but the wind is a strong 25 mph offshore – it’ll be clean but hard work to get out. The afternoon is better, with a moderate offshore breeze and 6ft of E swell. The period is short at 8 seconds, so it’s a bit of a windswell, but it’ll be fun and punchy.
Saturday the 12th of September morning is glassy – zero wind, 5ft of E swell, and clean conditions. The period is still short (8 seconds), so the waves won’t have that long-period punch, but it’ll be a fun, user-friendly surf.
Overall, the best session is Thursday the 3rd of September morning. Mark it in your calendar. After that, keep an eye on Friday the 11th and Saturday the 12th for clean, if not perfect, waves.
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.
