The Lowdown

Alright, surfers, Rusty here. Let's have a look at the next few weeks at Koeel Bay.

We’ve got a bit of a mixed bag coming up, with some real potential if you pick your moments. The window kicks off on Wednesday, 15th July, but honestly, it’s a bit of a write-off with poor conditions.

The real standout window starts on Thursday, 16th July. The early morning brings a glassy 5ft swell from the southwest, with a long 13-second period. That’s proper groundswell, and with the wind going totally glassy, it’s going to be clean. The water is a touch colder than average for this time of year at 58°, so you might want a decent spring suit. The combined energy is moderate (933). It’s a solid start to the day. The afternoon holds that glassy vibe too, with a clean 5ft SW swell. This is the best on offer for the near term.

The rest of the first week is a bit of a struggle. Friday morning, 17th July, is still nice and glassy, with a 4ft SSW swell, but it’s a bit weaker. After that, the wind swings around and messes things up with onshore and cross-onshore breezes through the weekend and into Monday.

There’s a big gap from the 21st of July through to the 23rd where the swell gets massive, but it’s also blown out. On the 21st, we’re looking at a 10ft swell from the SSW with a fresh cross-onshore wind at 22 mph. That’s a lot of energy (3338), but it’s going to be lumpy and messy. The 22nd and 23rd get even bigger, with the 23rd showing an 12ft SSW swell, but the wind is still cross-onshore. That kind of size is for experts only, and even then, it’s not clean.

The surf picks up again in a promising way on Saturday, 25th July. The afternoon session is a gem: a 5ft SSW swell with a clean cross-offshore wind from the SSE. This is going to be a beautiful, lined-up wave. Then on Sunday, 26th July, the morning is glassy with a 3ft SSW swell, but the real treat is the afternoon. You’re looking at a 5ft SSW swell, with an 18-second period – that’s very long period groundswell. The energy is strong (1557), and with the same clean cross-offshore wind, it’s going to be an excellent session for experienced surfers. This is the standout of the whole forecast.

The very end of the run, into the 28th and 29th of July, offers some clean, offshore conditions with moderate 4ft to 4ft SW swells, which will be a nice way to finish.

So, for the best waves, set your alarm for the morning of Thursday, 16th July, and then definitely clear your calendar for the afternoon of Sunday, 26th July. That second one is the one to wait for.

Rusty.

Information about the Koeel Bay Surf forecast

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