The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what Shark Pit’s got cookin’ over the next couple of weeks. I’ll be honest, the outlook is a bit of a mixed bag – mostly a waiting game for a couple of promising windows, but there’s plenty of flat or messy junk to wade through first.
The opening days are a struggle. Tuesday afternoon sees a weak 4ft swell from the WNW at a short 8 seconds, but it’s cross-shore wind and the combined energy is weak (277). The water's sitting at 55°, which is a degree cooler than usual for this time of year – you’ll feel that nip in the air. It’s just not worth paddling out for.
Wednesday through Saturday of the first week (5th–8th August) is a rough stretch. Swell drops right off, with heights barely scraping 3ft and most readings showing poor conditions. Even when there’s a bit of long-period energy (18 seconds on the Friday morning), the swell’s only 1ft. The wind is never your friend here – mostly cross-on or onshore. It’s a dry spell for clean waves.
We finally see some size building from Sunday the 9th, but it comes in raw. A 6ft NW swell at 10 seconds shows up, but it’s blown out by a moderate onshore breeze. By Monday the 10th, the combined energy jumps to a strong 1568 – that’s a proper push of 8ft NW swell at 9 seconds. The wind is light and cross-onshore in the morning, so it’s not total junk, but it’s a far cry from perfect. This is too big for beginners and borderline messy for intermediates.
The standout, if you can call it that, comes Tuesday the 11th morning. The swell hits 8ft from the NW at 9 seconds, with very strong total energy (1742). But here’s the kicker – it’s onshore wind again. That’s expert-only territory due to the size, and the onshore wind will chop it up. If you’re a confident charger, you might find a few, but it’s not the classic clean day we’re after.
The second week fades into a mix of smaller, longer-period swells. Saturday the 15th morning shows a small 3ft SW swell at 17 seconds (groundswell) with light cross-shore wind and moderate energy (685). That longer period may give some shape, but it’s inconsistent and small. The rest of the week is mostly onshore junk with heights under 3ft.
Bottom line: the only real shot at something waves is Monday 10th and Tuesday 11th, but the wind spoils it. There are a few marginal sessions scattered around, but nothing that’ll have you calling in sick. For a spot that’s fairly consistent, this is a lean run – but forecasts change, so keep an eye on the lighter winds.
Rusty.

Information about the Shark Pit Surf forecast
The above surf forecast table for Shark Pit provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Shark Pit can be found by selecting the local surf guide option on the grey menu. Our Shark Pit 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 (Shark Pit) 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 Shark Pit 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.
Shark Pit is 26 km (16 miles) from the city of Rohnert Park. If you plan a vacation in Marin County, look for hotels and other accommodation in Rohnert Park. Rohnert Park has rooms for a wide range of budgets as well as car hire and transport links.
