Alright, this is Rusty checking in with a look at the upcoming swell window for Onrus.

It's a bit of a mixed bag, but we've got a solid run of fun waves coming your way. The water's sitting at about 59°, which is just a touch cooler than what we'd normally expect for this time of year, so maybe a slightly thicker wetsuit is the call.

The real action starts from Sunday the 5th. We'll see a small but tidy southwest swell rolling in at 2ft with a 14-second period. The combined wave energy is moderate at 385, and with a light offshore breeze from the northwest, conditions will be super clean.

Monday the 6th steps it up a notch. The swell builds to over 7ft from the west-southwest, and the energy jumps to 1080. The real gem here is the Monday afternoon session. The wind goes glassy, and that 7ft southwest groundswell with an 11-second period will be offering up some excellent waves for experienced surfers. This is a standout.

Tuesday morning the 7th is looking similar with a clean 7ft swell from the southwest and a 12-second period carrying a combined energy of 1188. Offshore winds will keep things tidy.

After that, we hit a rough patch. From Thursday the 9th right through to the following Wednesday the 15th, the wind turns onshore and messy. There's plenty of energy in the water - pushing over 2400 mid-week - but the cross-onshore winds are going to chop everything up. It's a write-off for clean surfing.

Things finally settle down again on Monday the 20th. A fresh southwest swell fills in, and we get glassy conditions in the morning with a 3ft, 13-second period swell. The afternoon looks even better as it builds to 4ft with a clean offshore breeze.

If you want the best of it, definitely point your board at Onrus on Monday afternoon the 6th or Tuesday morning the 7th. That's where the magic is.

Rusty.

Information about the Onrus Surf forecast

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

Onrus is 6 km (4 miles) from Hermanus. If you plan a holiday in Overberg, look for hotels and other accommodation in Hermanus. Hermanus has rooms for a wide range of budgets as well as car hire and transport links.
