The Lowdown
Alright, let’s get into it.
The next couple of days are pretty flat and ordinary for Ravena. There’s surfable but uninspiring waves on offer Wednesday morning, nothing that’s going to get you out of bed early. It’s clean, but small.
Thursday drops off a bit, and Friday gets messy with a freshening southerly breeze and some lumpy cross-chop as a new S swell fills in. That one hits 6ft in the afternoon but it’s poor, so don’t bother.
That bigger S swell peaks overnight into Saturday, pushing up to 6ft with a long 12-second period, but the wind swings around to the northeast and it’s a cross-onshore mess. Strong wave energy and it’s just blown out. The setup looks more interesting for kite surfing than paddle surfing.
We get a bit of a breather Sunday – the swell backs down to around 4ft and the wind goes cross-off, but it’s still only marginal.
Now, Monday the 10th is where things start to get interesting. The swell builds back up to a clean 5ft from the SSE with an 11-12 second period. Wind is light and cross-off, and the conditions are described as very good. There’s a moderate amount of energy in the water, and the place should have some proper shape to it. This is your first real chance for a decent session.
Tuesday the 11th holds similar energy, with 5ft on the afternoon and light winds – glassy in the morning, clean in the afternoon. Good surf, but maybe not quite the standout that Monday is.
Wednesday the 12th gets a little more complicated with a cross-on breeze developing, and Thursday is cross-shore and a bit messy, though the swell hangs in there.
Now, Friday the 14th is the one to circle on the calendar. The swell pulses up to 5ft from the SSE with a solid 13-second period, and there’s strong wave energy pushing through. Morning winds are light and offshore, and the call is for excellent surf conditions for experienced surfers. This is the standout for the whole window. It’s a proper groundswell with some grunt to it, and with that offshore breeze, Ravena is going to have some clean, lined-up waves. The afternoon gets a bit cross-on, so make it a dawn patrol or a morning session.
The weekend after that turns to crap again. Saturday the 15th and Sunday the 16th get hit with strong cross-onshore winds and lumpy, poor conditions as the swell turns messy and short-period. The water gets a bit jumbled. Leave it.
Monday the 17th offers a small, clean window with 4ft, but it’s not much to write home about.
Then, hold on to your hats. Tuesday the 18th has another pulse of swell, pushing 8ft from the south with a 9-second period. The morning looks clean with light offshore winds and it’s marked as very good. This is a bigger, more powerful swell – not for the faint of heart. Over 8ft is expert territory, but 8ft is still a fair step up and will be too much for beginners. It drops off quickly after that, and the rest of the week looks poor with onshore winds and dropping swell.
So, my two picks: Monday the 10th for a fun, clean session, and Friday the 14th for the one with real size and power. That Friday looks like the best on offer – a long-period SSE groundswell with offshore winds. Get on it.
The water temp is about average for this time of year.

Information about the Ravena Surf forecast
The above surf forecast table for Ravena provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ravena can be found by selecting the local surf guide option on the grey menu. Our Ravena 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 (Ravena) 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 Ravena 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.
