The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, it’s a slow start. The surf is lean and the conditions are a bit messy. For the first week and a half, we’re looking at a lot of small, weak swell mixed with onshore or cross-onshore winds. The first few days from Tuesday the 14th through to the morning of Monday the 20th are mostly poor, with a few marginal windows. Winds are light to gentle, but they’re coming from the wrong direction, putting a chop on the surface. The combined wave energy is low, so there’s not much power behind it. You’ll be chasing ankle-biters if you’re keen.
The first real standout in the whole run comes right at the end of the first week, but it’s a long way off. Hold on for Thursday the 23rd of July. That afternoon, Seaside Reef finally gets a clean look. The wind swings light from the SSE, almost offshore, and the swell bumps up to 1.5m (about 5 ft) from the south with a 14-second period. The combined energy is solid, so there’s some proper grunt in the water. This is a true gem for experienced surfers. The water is sitting at 73°F, which is a massive 6°F warmer than normal for this time of year – very unusual, so you can leave the wetsuit at home. Given it’s a reef break with an inconsistent reputation, it’s not always gonna be working, but when it lines up like this, it’s special. Crowds are often an issue here, so get in early.
After that little spike, we roll into Friday the 24th and Saturday the 25th of July. The swell jumps up big time – 1.9m to 2.5m (6 ft to 8 ft) from the south with a 14 to 16-second period. The energy readings are massive, hitting a peak on Friday afternoon. But here’s the kicker: the wind is offshore from the west, which is clean, but the wave comments say it’s only marginal. The size is enough to get your heart pumping, but the consistency and quality might be a bit wonky. For a reef break, this long-period groundswell could be a bit straight and fat, but with offshore wind, it’s worth a gamble for the experienced crew. Beginners, stay away – over 1.5m (5 ft) is getting too big, and anything over 2.5m (8 ft) is for experts only.
The final week of the month, from Sunday the 26th onward, the swell drops back down to the 0.9m to 1.3m (3 ft to 4 ft) range. The energy is moderate, and the wind is mostly cross-onshore, so the quality fades. It’s not bad, but it’s not the standout. Overall, the best window is Thursday the 23rd afternoon and maybe the big, windy, powerful days on the 24th and 25th if you’ve got the skills.
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.
