The Lowdown
Alright, let’s talk the same story in feet and miles per hour.
The next 16 days at Seaside Reef are a bit of a waiting game. The best window is Monday, July 27th through Thursday, July 30th. We’ve got a solid, long-period groundswell from the SSW pumping in with combined energy readings in the 1091 to 1227 range, which is strong. Swell heights are around 4 to 6 feet, with a period of 14 to 19 seconds. That long period means the waves will have serious shape and power, perfect for a reef break. But the wind is cross-on or directly onshore for most of this, making it a bit choppy and lumpy. Water temp is about average for this time of year.
The standout is Thursday, July 30th. The morning shows a clean 6-foot swell from the south with a 14-second period and a light onshore wind from the WSW at 6 mph. The combined energy is a strong 1091. It’s not glassy, but the light wind won’t mess it up. This is the biggest surf you’ll see all week, so it’s for the advanced crew only, as it’s over the 5-foot threshold for beginners. The afternoon is similar, with a 5-foot swell. This spot is rare and inconsistent, so when it’s on, jump on it.
After that, from Friday, August 31st, the swell drops fast. We go from 6 feet down to 1 feet by the following week. The combined energy tanks from 982 down to 145. The wind stays light and onshore, but there’s no push. From Sunday, August 2nd through Tuesday, August 11th, the surf is flat. The data shows “poor surf conditions” for most of that run, with several days scoring a 0. It’s a long, dry spell. There’s a tiny bump on Saturday, August 8th afternoon, with a 3-foot SSW swell and a combined energy of 547, but it’s still marginal and not worth the drive.
The call is: Thursday, July 30th is your best bet. Get there early. The rest of the window is a bust.

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.
