The Lowdown
Alright, let’s get into it. The surf over the next couple of weeks is a bit of a mixed bag, with a few windows of clean potential and plenty of flat or stormy junk to sift through. The name of the game is picking your moments and not getting too greedy.
We start off at Geriba with a small, weak pulse on Tuesday afternoon. Swell is around `4 ft` from the south with an 11-second period, but the energy is still pretty weak (554) and the onshore wind from the ENE doesn’t help. The water temp is sitting at `72°F`, which is about average for this time of year, so no worries there. It’s clean, but it’s not doing much. Let’s call it a groveler’s session.
Wednesday and Thursday morning are pretty much a write-off—wave heights drop to under `3 ft`, and while Thursday morning has a bit more period (12s), the energy is just too weak. Thursday afternoon picks up a touch to `3 ft` with a longer 13-second period and light winds, giving us a glimmer of clean, lined-up walls. It’s small, no doubt, but it’s the first sign of life. The combined energy climbs to 328, so there’s a little more push in the water.
Friday morning sees a jump in size to `4 ft`, but it’s onshore from the WSW, which chops it up. By Friday afternoon, the wind backs off to a light east cross-off, and the swell holds around `4 ft` from the south with a 13-second period. This is a decent window—clean, with some push. Not a standout, but fun.
Saturday is a write-off. The morning is tiny (`2 ft`), and by the afternoon a strong southerly wind blows it out with a short-period `5 ft` that’s a mess. Forget it. Sunday sees a pulse of bigger swell—`6 ft` in the morning and `6 ft` in the afternoon—but it’s cross-shore and pretty jumbled. A lot of energy (639 and 989) but poor quality. It’s going to be lumpy and hard to read, and not worth the paddle unless you’re desperate.
Monday brings a solid offshore from the NE with `4 ft` of south swell, but the wind is fresh and the energy is moderate. It’s clean, but the forecast isn’t super inspiring. Tuesday is smaller again, and Wednesday morning has a bit of size (`5 ft`) but it’s onshore from the WSW. The best of this stretch looks like Thursday, the 17th. Morning has `4 ft` south swell with a 12-second period and a gentle NE offshore—clean, lined-up, and the energy is moderate (504). Afternoon holds `4 ft` with a 13-second period and a light cross-off, still clean. This is the pick of the first week if you can get out. Still small, but it’ll be worth it.
After that, it gets messier. Friday the 18th is blown out with strong cross-off winds. But Saturday the 19th throws a curveball: a solid `6 ft` from the east with a short 7-second period, but a solid NNE offshore in the morning. This is a bit of a wildcard—bigger, but short-period wind swell. The energy is strong (633), and with offshore wind it could be punchy and fun for the more experienced crew. That’s a possible highlight, but the period is short, so expect it to be a bit crumbly at a beach break like this.
Then it fades fast. Sunday and Monday drop off hard—`2 ft` and `0.7 ft`—basically flat with no push. The last gasp is Tuesday the 22nd with a tiny `3 ft` from the SSW and a 5-second period, which is just marginal. After that, it’s all onshore slop.
So, bottom line: don’t stress about the next few days. The best bets are Thursday morning/afternoon the 10th and Thursday the 17th for clean, small, lined-up waves. If you can handle some short-period punch, Saturday the 19th might have a bit more size, but it’s a gamble. Keep your expectations in check and pick the clean windows.

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.
