The Lowdown
Right, let’s have a look at what’s on offer. The first real surf window kicks off on Wednesday the 15th of July, but it’s not a long run of gold. The week ahead gives us a few clean windows, then it quietens right down for a few days, and the last week of the month might have some promise for the brave.
The standout session is Wednesday morning, 15 July at Geriba. Early, clean, with a gentle cross-off breeze from the NE at 9 mph. The swell is a solid 6 ft, coming from the SSE, with a period of 11 seconds, and the combined energy is moderate (724). That’s a lovely groundswell, and for a beginner-friendly spot, this is about as good as it gets. The water temperature is about average for the time of year, so no surprises there. Crowds are likely, but with waves like this, you’ll forgive them.
Thursday morning the 16th sees a fresh offshore breeze from the NNE at 19 mph, cleaning up a 5 ft SE swell (period 10 seconds, 525 energy). It’s a bit more wind-affected, but still rideable if you’re keen. After that, the swell drops and the wind builds. Friday and Saturday mornings have small, weak waves around 2 ft to 4 ft, and the offshore wind keeps it tidy, but there’s just not enough push.
Then it goes flat. From Sunday the 19th right through to the morning of Friday the 24th, we’re looking at tiny, weak dribble – mostly under 0.7 ft. The energy numbers are in the single digits to low 20s. That’s a proper gap. Not much to say.
Friday the 24th morning shows a little bump: 2 ft from the S, period 11 seconds, with a gentle offshore breeze from the NNE. The energy is low (194), but it’s clean. Not a standout, but it’s a sign of life.
The next real chance looks like Monday the 27th of July. A moderate cross-shore wind from the ESE at 13 mph, with a lumpy 6 ft SSE swell (period 8 seconds, energy 893). That’s got some power, but it’s short-period and the wind is side-on. The break is a beach, so expect it to be a bit messy and hard to line up. For experienced surfers only at that size, and honestly, it might be better for a kite session than a paddle.
The morning of Tuesday the 28th has a cleaner look with a 4 ft S swell (period 11 seconds, 410 energy) and a cross-off breeze from the NE. That’s the most promising of that later week, but still not a classic.
So, the best bet is clearly Wednesday morning, 15 July at Geriba. Go early, get the clean lines, and enjoy it while it lasts. After that, you’ll be waiting until the 27th or 28th for any real size again, and that’s a gamble.

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.
