The Lowdown
Alright, let’s talk about Seaside Cove.
Honestly, for the next couple of weeks, it’s looking pretty flat and frustrating. Most of the time, we’re looking at a lot of cross-shore or cross-onshore winds messing up the weak swell. The wave energy is weak to moderate, generally sitting below 600 (combined energy). It’s going to be a real struggle to find a clean wave for a while.
Let’s start from the beginning of the forecast. Saturday 25th July is a write-off. Cross winds from the South at 15 mph with a tiny 2ft to 3ft swell and a long period of 21 to 23 seconds. That’s a lot of energy (800) for such a small wave, but the wind just destroys it. By Sunday 26th, it’s much the same story – a bit of swell there, but cross and cross-onshore winds keeping it choppy.
Monday 27th and Tuesday 28th are more of the same. The swell sticks around 2ft to 3ft, but it’s all cross-onshore and choppy. It’s just not worth paddling out for the slop. We get a slight shift on Wednesday 29th with a NW wind, but it’s still cross-shore at 9 to 12 mph. The wave face is a bit cleaner in the morning, with a moderate cross-chop, but the swell is only 3ft at 17 seconds. It’s marginal, barely a 1 out of 10.
Honestly, the whole first week is a bust. We have a big gap of poor to non-existent surf until we get to the second week. The end of July and the start of August see the swell drop even further, down to 1ft with weak energy (152). There’s just nothing there.
Now, for the second week, starting Sunday 2nd August, the swell direction shifts to the West and West-Northwest, and the period drops to a short 7 to 8 seconds. The height creeps up to 3ft, then 3ft, and by Friday 7th August we see 5ft swells. But look at the wind – it’s still cross or cross-onshore the whole time. The wave energy picks up (371 on the 7th), but the poor surf conditions keep ruining it. It’s still a 0 or a 1 out of 10. For a beach and reef setup like Seaside Cove, that short-period swell with side wind just makes for a messy, choppy lineup. That 5ft on Friday morning is the biggest we see, but it’s blown out. On the last day, Sunday 9th August, we get a bit of hope with a cross-shore breeze in the morning, but at 4ft it’s still only marginal.
So, there isn’t a single standout day in the whole 16 days. The wind is almost always against us, or the swell is too small or too short-period to make anything of it. If you’re desperate, the mornings of 29th July and 9th August offer the best chance at a crumbly, waist-high wave with a slight chop from the North, but don’t expect much. It’s one of those runs where you’re better off waiting for the next forecast update.

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