Alright, let’s talk Jacobs Bay in the units you might be more used to. This is Rusty, and we’re going through it.
Your first decent session is Tuesday, July 7th. Morning, it’s glassy, no wind at all. The swell is running about 7 ft out of the southwest, period at 12 seconds. That’s a proper groundswell. Water temp is 59°, which is average for this time of year. The combined swell energy is sitting at 1439, so it’s got some real muscle. This is your standout – clean, powerful, but at 7 ft, it’s for the experienced crew only. Beginners, sit this one out.
Wednesday the 8th, morning hangs in there. Swell at 8 ft from the southwest, period 13 seconds, with a cross-off breeze from the SSE. Clean surf, energy jumps to 2430. Again, it’s got size and push.
Thursday the 9th, morning goes big. 10 ft from the SSW, period 14 seconds – that’s a long period groundswell. The energy is pumping at 5920. Cross-off wind keeps it clean, but 10 ft is only for experts at this spot.
Friday the 10th, another big morning, 8 ft from the SSW, clean, cross-off wind, energy 2517. Afternoon goes to 10 ft again, too big for most.
Saturday the 11th is your window for the intermediate crowd. Morning sees a 7 ft swell from the SSW, dead offshore wind out of the east at 3 mph. Energy is 1549. Clean, glassy, and manageable. Crowds sometimes, so get in early.
Sunday the 12th, morning drops to 5 ft, offshore breeze, clean. Fun, smaller.
Monday the 13th through Wednesday the 15th, it’s flat and ugly. Swells down to 2 to 3 ft, and on the 15th we get 25 mph cross-onshore wind with rain. Three days of nothing.
Thursday the 16th, a pulse comes back – 7 ft from the WSW, onshore wind, period 13 seconds, energy 1622. It’s there but not clean.
Friday the 17th, morning cleans up with a cross-off breeze and 5 ft from the WSW. Clean, good fun.
Saturday the 18th, small but tidy, 4 ft from the south, cross-off wind.
Looking into the second week, Sunday the 19th is a big standout. Morning is glassy, 10 ft from the WSW, period 11 seconds, energy 2047. Afternoon goes to 12 ft from the WSW, period 14 seconds, energy 3913. Glassy both sessions, but that’s expert territory only.
Monday the 20th, morning drops to 8 ft, cross-off breeze, energy 1387. Still big.
After that, the swell fades and gets messy through the 21st and 22nd.
Best of the whole period? Tuesday the 7th morning and Saturday the 11th morning. The 7th for that glassy power, the 11th for the offshore winds and a size you can handle. Sunday the 19th is one to keep an eye on, but it’s a big wave day.
Stay stoked.
Rusty.

Information about the Jacobs Bay Surf forecast
The above surf forecast table for Jacobs Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jacobs Bay can be found by selecting the local surf guide option on the grey menu. Our Jacobs 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 (Jacobs 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 Jacobs 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.
Jacobs Bay is 8 km (5 miles) from the city of Saldanha. If you plan a holiday in West Coast, look for hotels and other accommodation in Saldanha. Saldanha has rooms for a wide range of budgets as well as car hire and transport links.
