The Lowdown

Alright, Rusty here. Let's have a look at what's on the cards for the local line-up.

We've got a classic reef setup, and it's looking like a bit of a waiting game this week. The water's sitting at a pretty standard 60°F for this time of year, so no surprises there.

The kick-off is on Sunday morning, the 26th of July. It's not huge, but there's a solid 7ft SW groundswell rolling in with a 12-second period, and the energy is pumping at a strong 1358. The wind is glassy out of the ENE, which means the surface will be clean as a whistle. This is solid, powerful stuff for an intermediate, so it's not a beginner's playground. The crowd factor is a bit of a coin toss here, so you might have some company. This is the standout session of the first week, by a long shot.

Sunday afternoon sees the swell drop a touch to 6ft, but the wind swings to a cross-on from the SSW, making it a bit more of a fight. It's still surfable, but the morning window is the clear winner.

Monday and Tuesday, the 27th and 28th, are a write-off. The wind is howling onshore, and the swell jumps up to 12ft with a 17-second period, which is a lot of raw power (energy hitting 5899) but the wind is just trashing the surface. That's a no-go for a paddle board; the setup looks more interesting for kite surfing.

We get a brief reprieve on Wednesday afternoon, the 29th. The swell drops to 5ft SW, and the wind goes glassy again. The energy is moderate (838), but the clean conditions will make it fun.

Thursday morning, the 30th, offers a similar story with 5ft and glassy conditions, but the swell is a little smaller. After that, the wind gets messy again through the end of the month.

There's a bit of a gap with no real standouts until the 4th of August. Tuesday afternoon, the 4th, sees a pulse of 6ft from the WSW with 11-second period and a glassy ocean. The energy is moderate (1121), and it's labelled as excellent for experienced surfers, which is a solid call.

The real second-week standout is shaping up for Saturday afternoon, the 8th of August. We're looking at a clean 5ft WSW swell (energy 1193), but the wind is a solid offshore from the NNW. It's clean, it's manageable, and it's a much longer range call, so it's promising but less certain. The morning of the 10th also looks like a strong offshore, solid 6ft SW swell with a 17-second period, but that's a fair way out.

Keep your eyes on Sunday morning and that Saturday afternoon in the second week. The rest is a bit of a mixed bag.

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.
