The Lowdown
Alright, Rusty here. Let's have a look at what's coming our way for Seaside Cove.
Alright, first off, the water temp is sitting at 62°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus.
The next 16 days are a real mixed bag at Seaside Cove. We're looking at a bit of a slow start. The first solid chance of anything decent doesn't really roll in until Thursday the 3rd. The morning of the 3rd sees a solid 7ft of WNW groundswell, with a period of 11 seconds, creating a lot of energy out there (1223). It's a bit on the bigger side, maybe not for the groms, but the wind is a clean cross-off, so the shape should be there. That afternoon the swell drops slightly to 6ft, but the wind turns a bit more cross-on, so the morning is the pick there.
Now, Friday the 4th morning is a bit of a sneaky one. The swell drops right back to 4ft from the WNW, but holy moly, it's dead glassy. Zero wind. That's a rare gift. The energy is moderate (423), but for a smooth, clean log or a fun mid-length, that morning window is pure magic if you can get on it.
The following days are a bit of a write-off. Saturday the 5th and Sunday the 6th have tiny swell and poor winds. The energy is weak to moderate, and the frequent cross-shore chop will make it fustrating. A few days of marginal conditions follow, with Monday the 7th and Tuesday the 8th being particularly poor. Nothing to get excited about there at all.
However, there's a light at the end of the tunnel. Mark your calendars for Monday the 14th. The morning is looking like a real standout. We get a clean 5ft of WNW groundswell with a 12-second period, generating strong energy (821). The kicker? It's glassy again. This could be some of the best, cleanest surf of the whole period. This spot can get a crowd, especially when it's this good, so get in early.
The following days, Tuesday the 15th through the 17th, look a bit messy again with onshore winds and lumpy conditions, bringing the window to a close.
So, to sum it up: the absolute top pick is the glassy morning of Monday the 14th. Thursday the 3rd morning is another good call for a bigger, cleaner wave. The Friday the 4th glass-off is a sneaky good one for the small-wave crew.
Stay tuned, Rusty.

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.
