The Lowdown
Alright folks, Rusty here with a look at the stretch ahead for Seaside Cove. I gotta be straight with you: this is a tough one. The next 16 days are looking pretty flat and messy for the most part. We've got a long stretch of weak, short-period swell and less-than-ideal wind. The water temp is sitting at 61°F right now, which is about what you'd expect for this time of year, so no surprises there. The real story is the lack of any proper groundswell and almost constant cross-shore or cross-onshore breezes.
Let's break it down. From Monday the 3rd right through to the end of the first week, it's a write-off. We're looking at tiny waves, mostly under 3 ft, with a short period around 7 to 8 seconds, and a pesky cross to cross-onshore wind. The combined energy stays low, mostly in the 100-200 range (199 for Monday arvo, 104 Tuesday morning, etc.), but don't be fooled – the comment is "poor surf conditions" across the board. Wednesday morning the 5th sees a slight bump to 4 ft from the WNW, but with a period of just 8 seconds and cross-onshore wind, it's not going to be clean. It's all just a bit of a grovel.
The second week doesn't offer much relief either. Swell sizes stay tiny, often below 2 ft, and while we see some longer period swells (15 to 20 seconds) popping up from the SW, they're so small they won't produce any energy. The combined energy jumps around but stays mostly in the 200-300 range, and the wind is still onshore or cross-shore. Thursday the 13th morning has a glimmer of hope with 3 ft from the WNW and an 8-second period, but it's still only "marginal." Friday the 14th afternoon is probably the best of a bad bunch, with 4 ft from the WNW and a 7-second period, and a light cross wind. The combined energy hits 360, which is moderate, but it's still a short-period, onshorey mess.
Honestly, there's nothing here that gets me excited. The best call is Thursday the 13th morning or Friday the 14th afternoon, but even those are just "marginal" at best. The swell direction is from the WNW, which is not the optimum for Seaside Cove, and the wind is never properly offshore. The consistency is there, but it's consistently poor. For a beginner, anything over 5 ft might be too much, but that's not an issue here – the problem is the lack of quality. This setup looks more interesting for kite surfing than paddle surfing, if you're into that.
Hang in there, folks. It's a quiet spell, but the forecasts can change. Rusty signing off.

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.
Seaside Cove is 24 km (15 miles) from Astoria. If you plan a vacation in North Oregon, look for hotels and other accommodation in Astoria. Astoria has rooms for a wide range of budgets as well as car hire and transport links.
