The Lowdown
Alright, let’s get into it. It’s a pretty flat and quiet stretch ahead for the next couple of weeks. Honestly, we’re looking at a whole lot of small, weak surf with not much push behind it. The energy is all sitting at those low numbers, mostly under 500, which tells you the ocean’s just not putting out. The early part of the week is basically a no-go with wave heights hovering around 2ft to 2ft. The wind’s mostly onshore or cross-onshore, chopping up whatever tiny lines might try to show. You’d be fighting for scraps out there.
The first real glimmer of anything happens around Friday the 7th. The swell bumps up slightly to 3ft from the SSW with a longer period of 19 seconds. That’s a proper groundswell, and it pushes the combined energy up to 484, which is finally in that moderate range. But here’s the catch – the wind is cross-onshore at 9 mph, and the comment calls it “fairly choppy.” So, while there’s a bit more life in the water, it’s not going to be pretty. You might find a clean-ish wave between the bumps, but it’s a grind.
The weekend doesn’t offer much of an upgrade. Saturday the 8th and Sunday the 9th keep things around 3ft to 3ft with periods dropping back into the 15-17 second range. Energy stays moderate, in the 350-430 range, but again, those cross-onshore winds from the SSW and SW keep the surface a bit messy. It’s not terrible, but it’s not the kind of surf you’d set an alarm for.
Looking further out, there’s a slight tease around the 14th and 15th of August. The swell nudges up to 3ft to 4ft from the SSW, and the energy jumps into the strong range, hitting 664 and even 779 on the 14th. The period is solid, around 18 seconds, so there’s some real grunt behind it. The winds are more onshore, which is better than cross-onshore, but it’s still not glassy. The forecast calls it “marginal,” which means it might be worth a look if you’re desperate, but don’t expect perfection. This is the most promising window in the whole run, so if you get a chance on that Friday the 14th, it might be your best bet, but keep expectations in check.
The rest of the second week settles back down into the same pattern – small, weak swells, mostly under 3ft, with moderate energy. It’s all pretty average stuff. Nothing fires, nothing’s huge. It’s just a whole lot of nothing special for the next 16 days.

Information about the Seaside Reef Surf forecast
The above surf forecast table for Seaside Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Seaside Reef can be found by selecting the local surf guide option on the grey menu. Our Seaside Reef 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 Reef) 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 Reef 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 Reef is 1 km (1 miles) from the city of Encinitas. If you plan a vacation in San Diego County, look for hotels and other accommodation in Encinitas. Encinitas has rooms for a wide range of budgets as well as car hire and transport links.
