The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Cardiff Reef and, to be honest, it’s a pretty flat and frustrating run ahead. The whole 16-day window is a bit of a grind. We’ve got a long stretch coming up where the waves are just too small and weak to get excited about, with the first recommendation not kicking off until Thursday morning the 20th.
Let’s break it down. The swell energy is weak, sitting in the hundreds (323) on Thursday the 20th with a small 3ft SSW swell at 14 seconds. The wind is light but cross-onshore, so it’ll be a bit lumpy. That morning is the only real “maybe” with a score of 1 out of 10, which is the best we’ve got early on. The rest of that week and the next are filled with poor surf conditions—0s across the board—with tiny, weak swells of 2ft to 3ft and westerly offshore winds that aren’t doing much to help.
The water temperature anomaly is 0.0, so about average for the time of year.
There’s a small bump around Saturday the 29th of August and Sunday the 30th. The swell builds to 3ft to 4ft from the SSW, with a solid period of 16-17 seconds, and the energy jumps up into the moderate range (719 on Saturday afternoon). Winds are light westerly offshore or light cross-onshore, so conditions are actually pretty clean. This is the standout stretch. Cardiff Reef is a very consistent reef break, so it’ll be breaking. Expect crowds to be possible here on the weekend, but that’s a price worth paying for the best waves on offer. For the average surfer, that 3ft to 4ft is a fun size. Beginners can still get amongst it.
After that, it fades again into early September with weak 2ft to 3ft surf and some more marginal conditions.
So, if you’re keen, keep your eyes on that weekend of the 29th and 30th of August. That’s your best chance for a paddle. The long-period groundswell (over 15 seconds) will mean better-shaped waves with more energy, but longer lulls between sets. It’s a reef, so it should hold the swell well.
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.
