The Lowdown
Alright folks, Rusty here. Let’s get straight into the outlook for Third Reef.
Right off the bat, I gotta be honest with you – the next week and a half is a bit of a write-off. We’re looking at a solid chunk of time from this Sunday morning, July 26th, all the way through to the 4th of August where the conditions are just not cooperating. The swell is there, but it’s getting murdered by a persistent cross-onshore wind that keeps the surface choppy and lumpy. The combined wave energy is actually moderate to strong (values between 971 and 1303), but it’s messy. The water temp is sitting at a very warm 61°F, which is 5°F above normal – that’s way warmer than usual for this time of year, so at least you won’t be freezing your bits off while you’re staring at the choppy mess.
The real standout here is a window that opens up much later. We’re talking about Wednesday afternoon, August 5th, into the following Sunday, August 9th. This is where things get interesting. The wind drops right out, going glassy or very light offshore, which is a massive positive for this exposed reef break. The best of the best is clearly Sunday, August 9th. You’ve got a clean 7ft to 8ft swell from the NW, with a solid period of 10 seconds, pushing a strong combined energy of 1192 to 1420. This is heavy, powerful groundswell that’s going to unload on the reef. This is for experienced surfers only – at over 8ft, it’s a big day. The water is still likely to be very warm, and the glassy conditions will make it a classic session. It’s a long way off, but it’s the one to circle on the calendar. The Saturday afternoon before it, August 8th, also looks clean with a smaller 3ft SSW swell to get your eye in.
Because the wind is cross-on for almost the entire period, the setup at Third Reef is more interesting for kite surfing than paddle surfing for most of the first two weeks. The only true standout is that Sunday, August 9th. Keep your fingers crossed that the long-range forecast holds.
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.
