Table - best surf conditions forecast for Onrus over the next 16 days.
Alright, let’s talk Onrus in feet and Fahrenheit. Water temp is 59°, right on the money for this time of year.
It’s gonna be a slow burner. Friday the 10th brings an 8ft SSW swell at 13 seconds, but that 12 mph east wind is onshore and chunky, making a mess of things. Energy is huge at 2230. Saturday and Sunday are a total loss with poor conditions. We’re looking at a few days of nothing.
Monday the 13th is tiny and messy. Tuesday the 14th is the first clean one – a light offshore from the WNW, but the waves are only 2-3ft. Clean, but nothing to write home about.
The first real standout is Thursday the 16th. Morning session. An 8ft SW swell with a 13-second period, light cross-offshore wind from the west, and glassy conditions. This is an expert-only wave – powerful, clean, and holding plenty of energy (2108).
The second standout is Sunday the 19th. The morning is dead flat calm and glassy. A 7ft WSW swell at 12 seconds. Clean, powerful, and will have a few heads out. Crowds are possible.
Wednesday the 22nd is another good morning for experienced surfers, and then Thursday the 23rd looks huge – 11-12ft from the SW – but it’s just too big for this spot. Friday the 24th and Saturday the 25th both look excellent early with glassy conditions and solid 6-7ft swells, but that’s a long way out, so don’t bank on it.

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.
