The Lowdown
Alright folks, Rusty here. Let’s have a look at what Boiler Bay is cooking up over the next couple of weeks.
The overall pattern is a bit of a mixed bag. We’ve got some decent pulses of energy coming through, but the wind is going to be our biggest enemy for a lot of this run. The water is running *much colder than normal* for this time of year, sitting at 53°F, so a thick wetsuit is non-negotiable.
We kick things off on Wednesday, August 19. The afternoon sees a 3ft WNW swell at 12 seconds, but with a cross-on breeze it’s just too choppy to get excited about. The combined energy is moderate at 477. Not the start we wanted.
Thursday, August 20, is a little better but still marginal. The morning has a 5ft WNW swell (688 energy) and a light cross-on wind, but the surf is just average. The afternoon drops to 4ft and the wind stays cross-on. Nothing to rush for.
Friday, August 21, is where it starts to look interesting. The morning has a clean 2ft SW groundswell at 14 seconds. The wind is light and cross-off, making for clean conditions. It’s small, but the quality should be there for a longboard or a fish. The energy is moderate at 450.
Saturday, August 22, is the first real standout. The morning sees a 3ft NW swell, but it’s short-period at 8 seconds. The wind, however, is a moderate offshore from the SSW, and it’s clean. The energy is 259. The afternoon stays clean with a cross-off breeze. This is your best bet for the first week if you want a fun, clean session.
Sunday, August 23, goes backwards. The wind swings onshore and builds, with a 5ft NW swell getting blown out. The combined energy climbs to 395, but it’s messy. This is a write-off.
From Monday, August 24, right through to Saturday, August 29, we hit a dry spell. The wind is mostly onshore and strong, and the swell is small and weak. There are long gaps of poor, unsurfable conditions. It’s a frustrating run.
Sunday, August 30, offers a glimmer. The morning has a clean 2ft SW groundswell at 16 seconds with a light cross-off breeze. The energy is 372. It’s small, but it’s clean.
The real highlight, and the best on offer in the entire forecast, lands on Monday, August 31. We’ve got a 5ft NW swell, short period at 8 seconds, but the wind is a moderate offshore from the SSW. The conditions are clean and the energy is strong at 506. The afternoon session is just as good with another 5ft NW swell at 528 energy. This is the day to clear your schedule. The sets will be punchy and the offshore wind will hold them up nicely. This is expert territory though, as the swell is pushing over 5ft.
After that, we fade out. Tuesday, September 1, goes back to marginal with a light cross-shore wind, and then from Wednesday, September 2, through to Thursday, September 3, the onshore wind returns. On Thursday the 3rd the swell is a massive 7ft at 14 seconds with a huge 1720 energy, but it’s blowing 25 km/h onshore, so it’s a complete mess. That one’s for the kites, not the surfers.
Keep your eyes on the 31st of August. That’s the one.
Rusty.

Information about the Boiler Bay Surf forecast
The above surf forecast table for Boiler Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Boiler Bay can be found by selecting the local surf guide option on the grey menu. Our Boiler Bay 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 (Boiler Bay) 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 Boiler Bay 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.
Boiler Bay is 70 km (43 miles) from Corvallis. If you plan a vacation in North Oregon, look for hotels and other accommodation in Corvallis. Corvallis has rooms for a wide range of budgets as well as car hire and transport links.
