The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
We’re looking at a pretty quiet run overall. The only spot that’s even in the mix is Seaside Reef, a tricky reef setup for advanced surfers only. It’s inconsistent, so don’t bank on it firing every day. The best of it is right at the start, on Wednesday 29th July. We’ve got a clean 4ft SSW groundswell pushing in from the west-southwest, with a long 16-second period. That’s real energy, with a moderate combined swell energy of 757. The wind is offshore and light, making for clean, glassy conditions. The water is a balmy 76°, which is much warmer than normal for this time of year – a full 9° above average.
Thursday morning, 30th July, still offers some fun. The swell drops slightly to 4ft from the south, with a similar 13-second period, and the wind shifts to a light westerly offshore. The energy is still decent at 945. It’s a notch down from the Wednesday, but still the pick of the first few days.
After that, things get grim. From Friday 31st July right through to the end of the 16-day window, we’re looking at a long stretch of poor surf. The swell drops below 3ft, the period shortens, and the wind turns cross-onshore, putting a bump on the surface. The combined energy drops into the 100-500 range, which is weak. The scores are all zeros or ones, meaning the conditions are just not worth paddling out for. That’s a solid two-week gap with no real recommendations.
So, if you’re keen, make the most of Wednesday 29th July at Seaside Reef. It’s the standout. The rest of the forecast is a write-off, but that’s how it goes sometimes – the forecasts can change, so don’t lose hope.
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.
