Alright, Rusty here. Let’s have a look and see what we’ve got for Seaside Cove over the next couple of weeks.

Honestly, it’s a bit of a slow start. The first week or so from Monday the 6th right through to about the 18th of July, you’re looking at a long stretch of poor to marginal conditions. The waves are there, but they’re mostly small—around 2ft to 4ft—with a lot of cross-onshore or cross wind making things choppy and messy. It ain’t really worth paddling out for, unless you just want a float in a wetsuit. There’s moderate wave energy in the water (around 430 to 500 combined energy units), but the quality just isn’t there for a decent surf.

The water temp is sitting at 59°, right on average for the time of year, so nothing wild there.

Now, looking ahead, there’s a real glimmer of hope. The standout surf for this whole outlook comes on Sunday the 19th of July. We’ve got a solid 5ft swell rolling in from the NW, with a period around 8 seconds. But the real kicker is the wind. Sunday morning, it’s a light cross-offshore breeze, and then by Sunday afternoon, it goes glassy. Complete glass. The combined energy is moderate to strong (486 in the morning, 374 in the afternoon), and the forecast is calling for "good surf conditions". This is the one to aim for. The direction is matching the optimum swell direction for the break, and with that kind of clean, glassy surface, Seaside Cove (beginner-friendly, consistent spot) will be peeling off nicely. Just keep in mind it’s a popular spot, and with conditions that good, crowds are likely, so get down early.

After that, Monday the 20th sees the same size swell but the wind swings back onshore, and it gets messy again through the rest of the forecast.

So, to sum it up: a long blank run of weak, onshore slop, but the 19th of July is your day. That Sunday has real promise—clean, glassy, and with enough swell to actually have some fun.

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.

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.
