Table - best surf conditions forecast for Seaside Cove over the next 16 days.
Alright, Rusty here. Let’s have a look at what’s on offer for the next two and a bit weeks.
The truth is, for the first week and a half, it’s pretty grim. Nothing’s really coming together for a good session. We’re looking at a long stretch of poor surf conditions and marginal calls, with a lot of cross-on or cross-shore wind messing up the surface. The first real chance to get wet doesn't show up until Saturday the 18th of July, and even then it’s a maybe.
The standout of the whole forecast is Saturday the 18th of July, afternoon. Seaside Cove is a mix of beach, reef, and point, so it gives you options. We’ll see a 5ft swell coming from the WNW with a short period of 8 seconds. The combined energy is moderate, at 528 (moderate wave energy). The wind is light cross-shore, which is a major positive – it’ll keep things clean with just small crossing ripples. The water is a bit colder than normal for this time of year at 57°F (a -2°F anomaly), so you’ll want a decent wetsuit. Crowds are possible here, so keep an eye out. For a beginner, this swell is manageable, but the short period means the waves won’t have much grunt.
The next little window is Sunday the 19th of July, morning. We’ve got a 4ft WNW swell, with an onshore wind from the W at 6 mph. The combined energy is 433 (moderate wave energy). It’s a marginal call though, and the onshore wind is a bit of a letdown. The afternoon is similar, but with cross-on wind, not as clean.
After that, the end of the week and into the next week shows a lot of similar stuff: marginal surf with cross-on winds. The 22nd and 23rd of July see a bump in size to 5ft and 6ft from the WNW (9-second period), but the combined energy jumps to 523 and 588 (moderate to strong wave energy). The wind is cross-shore, which is okay, but it’s still a bit messy. The swell is getting big enough that it’s not ideal for beginners. It’s more of a solid option for experienced surfers, but the quality is still only marginal.
Honestly, if you’re desperate, the 18th afternoon is your best bet. The rest of the time you’re fighting the wind or the chop. It’s a tough run.

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.
