The Lowdown
Alright folks, it’s Rusty here. Let’s get into it. We’re looking at a long stretch ahead for Moonlight Beach, and I gotta be straight with you—it’s a tough one. The first real surf that’s worth paddling out for doesn’t show up until the morning of Tuesday the 8th, and even then, it’s a bit of a grind.
The overall pattern? We’ve got a persistent, weak SW groundswell trying to push in, but the wind is mostly a problem. Combined swell energy is moderate, hitting values around 558 on Tuesday morning, but it’s a cross-on breeze that’s killing the quality. The wave comment is “marginal” at best. The water temp is a standout though—72°F, which is over two degrees warmer than usual for this time of year, so the water feels like summer.
For the first week, from the 8th through the 14th, there’s really nothing to get excited about. The swell is tiny, mostly under 3 ft, and the wind keeps shifting between cross-on and cross, with a lot of moderate breeze making it choppy. The afternoons are particularly rough. The one slight glimmer is on the morning of Wednesday the 10th with a 3 ft SSW swell out of the SW at 17 seconds—that’s some real long-period groundswell, which means better shaped waves and longer waits between sets. But the wind is cross-on, so it’s not clean. For a beginner spot that’s inconsistent anyway, this is a pass.
The second week, from the 15th onward, sees a slight uptick in consistency, but the swell height stays small—mostly 2 ft to 4 ft. The real highlight, if you can call it that, is on the morning of Sunday the 20th. We’ve got a 3 ft SW swell from the SW, period 19 seconds, with combined energy at 734. That’s moderate energy, and the wind is light cross-on, so it’ll be a bit bumpy but workable. The period is very long, so it’s gonna be a bit straight at this beach break, but the gaps between sets will make paddling easier. The other notable one is Monday the 21st morning, with a 4 ft SW swell from the SW, 17 seconds, and combined energy at 755. That’s the best combined energy of the whole run. Again, light cross-on wind, so not glassy, but it’s the closest we get to clean.
The crowd factor at Moonlight Beach is “sometimes,” so you might have company, but nothing crazy. The big issue is the break is “inconsistent” and the overall quality scores are low. There’s a gap of several days with no real recommendations, especially the first week, where it’s mostly poor or marginal. This is a tough period—if you’re desperate, the mornings of the 20th and 21st are your best bets, but don’t expect a classic.
Stay patient, and remember, forecasts can change. Rusty out.

Information about the Moonlight Beach Surf forecast
The above surf forecast table for Moonlight Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Moonlight Beach can be found by selecting the local surf guide option on the grey menu. Our Moonlight Beach 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 (Moonlight Beach) 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 Moonlight Beach 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.
Moonlight Beach is 6 km (4 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.
