The Lowdown
Alright, grab your board, let's talk about what's on the menu for the next couple of weeks. It’s a bit of a slow start, but there’s a light at the end of the tunnel.
First thing to know: the water is sitting at 72°, which is pretty much standard for this time of year. Nothing wild there.
The first few days are a tough watch. From Thursday, the 16th, right through nearly a full week, the swell is tiny and the wind is just too strong. Even though it’s offshore, that fresh breeze is making it a battle. The waves are small, the energy is weak, and frankly, it’s not worth paddling out for. We’re looking at a solid six-day lull here.
Now, things start to perk up a little on Thursday, the 23rd. The wind goes glassy in the morning, and we get a tiny 2 ft S swell. It’s small, but it’s clean. You could get a few sneaky ones, but don't expect fireworks.
The real standout window comes on Friday, the 24th. That morning, Geriba shows up. We’ve got a clean 4 ft swell from the south with a period of 12 seconds, so it’s a proper groundswell, holding some shape. The wind is a moderate offshore from the NE, keeping it tidy. The energy is moderate, about 393, and it’s consistent. This is your best bet of the whole period. It’s not huge, so it’s a good level for a beginner spot, but it will be a fun one. Crowds are often a thing here, so get there early.
Don’t get too excited about the weekend after that. The 25th and 26th bring a bigger swell, around 6 ft, but the wind goes onshore and nasty. It’s going to be bumpy, choppy, and blown out. That’s kite-surfing stuff, not for a clean paddle.
The last few days of the month show a little pulse of energy on the 31st of July, with a 4 ft SE swell and a long 13-second period, but the wind is still fresh offshore. The energy is strong (676), but it’s a bit of a tease. The conditions are marginal, so it’s a maybe, but Friday the 24th is the one to circle on your calendar.

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.
