The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Third Reef over the next couple of weeks.
Honestly, the first week is a bit of a write-off. We're looking at a long stretch of poor conditions right through until the end of July and into the first few days of August. The wind is mostly a moderate to fresh cross-onshore, which is just chopping everything up. The swell is there, but it's messy and the wind is killing it. There's a glimmer of something bigger on the 1st and 2nd of August, with the swell jumping up to 6ft to 8ft, but the wind is still howling cross-on from the NNW at 15 to 19 mph, making it look more like a kite session than a paddle surf. You'll have to sit this one out for now.
Now, the real story starts to shape up on Monday the 3rd of August. Monday morning we see a serious pulse of energy from the NW, with swell hitting 10ft and the combined energy spiking to 2374. But the wind is still a factor, blowing cross-on, so it's a bit of a beast to handle. The standout moment is Monday afternoon. The wind drops to a glassy 3 mph from the NW, and while the swell drops to a more manageable 7ft, it's smooth as silk. This is the best on offer, but at 7ft it's a solid expert wave. The water is a balmy 61°F, which is much warmer than normal for this time of year, so you won't need the thickest of suits.
We get a bit of a lull through Tuesday and Wednesday (the 4th and 5th), with smaller, less clean conditions. Then, hold on for the weekend. Saturday the 8th of August and Sunday the 9th of August look like the real highlights. Saturday serves up an 8ft NW swell with a combined energy of 2433, and light winds. But the absolute gem is Sunday the 9th of August afternoon. The wind goes dead calm, glassy, with a solid 7ft NW swell. The combined energy is a healthy 1143, and the period is a nice 10 seconds. This is going to be clean, powerful, and perfect for the experienced crew. The period is long enough to give you a proper groundswell feel, but it might be a bit straight for beach breaks, but for a reef like Third Reef, it's going to be excellent.
The session rolls into Monday the 10th and Tuesday the 11th of August, with clean, glassy conditions on Tuesday afternoon, with a 6ft NW swell. It's a solid finish to the run.
Overall, don't bother for the first week. The real action is from the 3rd of August, with the standout being Sunday the 9th of August afternoon. Mark it in your calendar.
Rusty.

Information about the Third Reef Surf forecast
The above surf forecast table for Third Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Third Reef can be found by selecting the local surf guide option on the grey menu. Our Third 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 (Third 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 Third 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.
Third Reef is 85 km (53 miles) from Eureka. If you plan a vacation in Humboldt County, look for hotels and other accommodation in Eureka. Eureka has rooms for a wide range of budgets as well as car hire and transport links.
