The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Cardiff Reef over the next couple of weeks.

Honestly, mate, this is a tough one to call. The water is a warm 72°F, which is much warmer than normal for this time of year, but the surf is in a real slump. We’re lookin’ at a long stretch of nothing special, with the first real glimmer of a session not poppin’ up until the back half of the run.

The first real standout I can point you toward is Monday morning, September 7th. The swell will be up around 6ft coming from the SSW with a solid 13-second period, and the combined energy is a chunky 1085 (moderate wave energy). That’s a bit of a jump from the tiny stuff before it. The wind is from the WNW at 9 mph, which is a cross-on, so it’ll be a bit messy, but there’s enough juice in the water to get a few good ones. This is probably the best look of the entire forecast, but it’s only for the intermediate crew; 6ft is pushing it for beginners.

After that, Tuesday, September 8th, offers a bit of a drop. The morning swell is 5ft from the SSW, with a clean 11-second period, and the wind goes light and onshore from the WNW at 6 mph. It’s a tricky one with the wind direction, but it’s a whole lot cleaner than Monday. The combined energy sits at 663 (moderate). It’s a definite “maybe” session.

The rest of the first week and into the second is a real grind. The swell drops off to 2ft to 3ft with poor wind directions, mostly cross-onshore. The combined energy values are all in the weak to moderate range (under 600). The 16-day run is mostly a write-off for quality waves.

There is a bit of a pulse in the second week, but it’s nothin’ to get excited about. Around Monday, September 21st, we see a marginal return of swell at 3ft from the SSW with a 16-second period, combined energy of 561 (moderate). The wind is a light cross-on from the SW, which might clean it up a bit. It’s a long-range call, so don’t bank on it, but it’s the only thing that looks like a surfable option in the final days.

Bottom line: The best bet is Monday morning, September 7th, for the biggest swell. After that, it’s a waiting game.

Rusty.

Information about the Cardiff Reef Surf forecast

The above surf forecast table for Cardiff Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cardiff Reef can be found by selecting the local surf guide option on the grey menu. Our Cardiff 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 (Cardiff 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 Cardiff 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.

Cardiff Reef is 3 km (2 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.
