Alright, let’s get into it. I’m lookin’ at Third Reef, and honestly, the next few days are a bit of a mixed bag. There’s some swell on the way, but the wind is going to be a pain for most of it, with a lot of cross-on conditions keeping things choppy and messy.

The first real chance to get something decent is on Saturday, July 4th. Saturday afternoon is where it’s at, with a glassy surface and a clean 5ft swell coming from the NW. The water’s a bit colder than usual for this time of year, sittin’ around 53°F, but that’s nothin’ a good wetsuit won’t fix. This is a reef break, so it handles a long period swell well, and it’s got some decent energy pumping. It’s a bit tricky though – the break is fairly consistent, and crowds can be a problem sometimes, so get out there early if you can.

After that, it gets a bit frustrating. There’s some pulsey SSW groundswell coming in from July 5th onwards, but it’s mostly cross-on wind and poor surf conditions until about July 15th. You see some really long period swell in there—18, 19, even 20 seconds—but the wind just won’t cooperate, making it a bumpy, lumpy mess with moderate to fresh breezes.

The big standout is later in the second week, on Friday, July 17th. The morning shows a solid 7ft NW swell with a period of 9 seconds, and the energy is cranked up – that’s strong, powerful stuff. But the afternoon is the real gem. The wind drops to glassy, and we get a 8ft NW swell with excellent conditions for experienced surfers. That’s the one to circle on your calendar. It’s too big for beginners, but for anyone with a bit of skill, that’s a session you won’t forget.

Overall, there’s a lot of waiting for the right moment, but Saturday afternoon, July 4th, and Friday afternoon, July 17th, are your best bets. Keep an eye on those windows.

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.
