The Lowdown
Righto, let's have a look what's on the menu for Jacobs Bay over the next couple of weeks.
Look, it's a rough start. We've got a massive pulse of energy coming in for the next few days, but it's just too much for this spot. The water temp is about what you'd expect for this time of year, nothing weird there. There's a staggering 5447 (combined energy) swell roaring in Wednesday morning with a 10ft south-west swell, but that's just way too big and messy for a beginner's wave. The wind is a strong cross-off, so the face might be clean, but the size is the big problem. Wednesday afternoon is still solid at 7ft, but the score tells you it's not happening. Thursday keeps the trend going with 6ft in the morning and then another 10ft pulse in the afternoon – same story, too much grunt.
Honestly, the first weekend isn't much better. Friday and Saturday both have surf in the 5ft to 5ft range with a moderate to fresh breeze, but the conditions are just "marginal" at best. It's not totally blown out, but it's not clean enough to get excited about. We're looking at a gap of pretty poor options until we get to Monday the 21st. That's a long time to stare at a flat, messy ocean.
Alright, here's the standout of the whole forecast. Monday morning, the 21st of September. That's your window. The swell drops to a super manageable 4ft from the west-south-west, with a 12-second period – that's proper groundswell, meaning it'll wrap in nicely and have some shape. But the real magic is the wind: glassy. Absolutely dead flat, 3 mph from the south-south-east. It's going to be clean as a whistle. The energy is a moderate 569. For a spot like Jacobs Bay, that's the goldilocks zone. Keep an eye on the crowd situation though – it can get "sometimes" busy, and on a morning like this, it'll be a popular choice.
After that, it goes a bit ordinary again. Tuesday the 22nd is small and choppy. Wednesday the 23rd is even smaller with a howling near-gale wind in the afternoon. Then we get another one of those massive swells hitting on Thursday the 24th – 10ft again, but this time with a moderate offshore breeze. It's clean, but the sheer size (2608 combined energy) means this is strictly for experts only. It'll be a freight train. Friday the 25th is still chunky at 7ft, but the wind is cross-onshore, which will chop it up.
The second week fades out pretty quietly. There's a couple of sessions worth a look, like Monday the 28th morning with a 4ft south-west swell and clean conditions, but it's weak and inconsistent. The last real note is the very end of the forecast, on Thursday the 1st of October. It's tiny, 2ft, but glassy again with a super long 16-second period from the south-west. It'll be a long wait for a set, but if you're a logger, might be a laugh.
So, to wrap it up: the first week is a tale of two problems – too big or just average. The absolute best bet is Monday the 21st of September morning. Get in the water then. And if you're game for a big, clean, expert-only wave, Thursday the 24th of September morning will be a sight to see.

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.
