The Lowdown
Alright, I’ve scanned the charts for Otter Rock over the next couple weeks, and I gotta be straight with ya – it ain’t looking flash. We’ve got a clear run from Sunday the 16th of August, but the wind and swell just aren't cooperating.
For the first ten days or so, it’s all cross-onshore wind out of the NNW, keeping the surface all chopped up and messy. The water is a freezing 54°F, and that’s about 5°F colder than average for this time of year – that’s very unusual, so you’ll need a thick suit.
We start off Sunday the 16th with tiny, weak 2-foot swell from the SW at a very long 16 seconds, but that NNW wind at 12 mph just messes it all up. Energy is weak at 313. That pattern sticks around – Monday and Tuesday both show small 2-foot waves and poor conditions. Wednesday the 19th bumps up slightly to 3 feet from the WNW, with moderate energy around 475-492, but that cross-onshore wind is still there, so it’s still choppy.
We get a slight flicker on Thursday morning the 20th. The swell pushes up to 5 feet from the WNW with an 11-second period, and the energy jumps to 688. The wind drops to a light breeze from the NW. It’s still cross-onshore, so it’s not clean, but it’s the least rough we’ve seen. It’s only a marginal call – questionable tide. Friday morning the 21st actually gives us some offshore wind, light from the WSW at 3 mph, but the swell drops back to 4 feet from the NW with a short 8-second period. Still only marginal.
From there it goes downhill. We see bigger swell on the 23rd (5 feet) but the wind cranks up to a fresh 19 mph cross-shore breeze, making it a lumpy, cross-chop mess. That’s kite-surfing weather, not paddle surfing. The period is super short at 7–8 seconds, so the waves will be weak and crumbly.
There’s a long gap of really poor, unrideable conditions through the 24th to the 29th. We finally get another mention of decent size on Monday the 31st – 5 feet from the NW with an 8-second period and moderate energy of 601-613. The morning shows a light cross-onshore breeze, but it’s still only a 2 out of 10 – marginal at best.
Honestly, if I had to pick the only real standout, it’s Thursday morning, August 20th. That 5-foot WNW swell with an 11-second period has the most energy of the near-term, and the light breeze makes it the least messy. It’s still not perfect, but it’s the closest we get to something worth paddling out for.
Apart from that, this is a real quiet stretch. Don't hold your breath.

Information about the Otter Rock Surf forecast
The above surf forecast table for Otter Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Otter Rock can be found by selecting the local surf guide option on the grey menu. Our Otter Rock 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 (Otter Rock) 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 Otter Rock 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.
