The Lowdown

Howdy folks, Rusty here, checking in on the prospects for Seaside Reef over the next couple of weeks. We’ve got a slow start and a big finish, so let’s talk it through.

First up, Seaside Reef is an inconsistent spot, and we're in a quiet phase. The water temp is a warm 77°F, which is much warmer than normal for this time of year – definitely a nice surprise.

Your first real look at the ocean comes Saturday the 30th of August. There’s a 4ft SSW groundswell with a long 16-second period, so there's some real pull. But the light 6 mph WSW wind is onshore, so the surface is going to be a bit messy. The combined swell energy sits at a moderate 728, meaning there's some push, but it’s a marginal call. One for the die-hards only.

Things stay pretty quiet and frustrating from Sunday the 30th right through until Sunday the 7th of September. We’ve got a few mornings with waist-high S or SSW swell, but the winds are nearly always onshore or cross-onshore, keeping things lumpy and uninviting. The Tuesday morning of the 2nd offers a 4ft SSW swell with a 12-second period, but again, the wind is onshore. It’s a long stretch of mostly poor to marginal surf. Best to save your energy.

Now, the second week is a whole different story. Monday the 8th of September picks up steam, with 6ft of S swell by the afternoon and a light offshore breeze from the WNW at 6 mph. That’s a promising setup, with combined energy surging to a strong 1171. The true standout, though, is Tuesday the 9th of September. The morning serves up a chunky 8ft SSW swell with a 13-second period and light offshore wind, pushing the energy over 2000. Then the afternoon goes ballistic – a massive 13ft SSW swell with a 12-second period, combined energy screaming to 4167. That’s a serious, powerful groundswell, and with light offshore winds from the W at 9 mph, it could be absolutely perfect. But for sure, anything over 8ft is expert territory. This is a heavy-duty session for the brave hearted. This is your big stand-out.

After that peak, it fades quickly. From Wednesday the 10th of September onward, it drops back into small and poor conditions. There’s a little bump on Sunday the 14th with a 4ft SSW swell and a manageable 13-second period, but the wind coming through with rain showers keeps it marginal.

So to wrap it up: the first ten days are mostly a dud. But that Tuesday the 9th of September is a day to circle on your calendar – just make sure you’ve got the skills and the nerve.

Rusty.

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.
