The Lowdown
Alright, Rusty here. Let’s talk about Tarantulas.
This is a beach and reef break, exposed, and it needs the swell to come from the southwest to really line up. The water’s sitting at 66°F, which is a touch warmer than usual for this time of year – you’ll notice it.
The first real push comes Sunday the 13th, with 10ft of NW windswell at a short 8 seconds. The combined swell energy is strong at 1360. Problem is, the wind is howling 22 mph from the NNW – cross-offshore, so the surface is clean, but that’s a lot of lumpy, short-period power. It’s a “marginal” call because of tide or conditions. Monday the 14th drops to 7ft, but the wind goes cross and the quality fades. Tuesday the 15th still has 7ft but a light cross-onshore breeze – small ripples, nothing clean.
Honestly, the first week is a struggle. The real standout comes much later. On Monday the 28th, we get 7ft from the NW in the morning, and the combined energy jumps to 1426. The wind goes cross-off from the NNW by the afternoon and it’s clean – that’s the best session in the whole forecast. It’s still only “marginal” on paper, but it’s the biggest, cleanest punch. The 25th of September afternoon is a solid backup with 5ft, 10 seconds, and cross-off NNW wind – clean, but less power at 786.
Tarantulas doesn’t give up the good stuff easily. When the swell is over 5ft with short period, it gets heavy. Over 8ft is for experts only. The 13th and the 28th both push past that mark.
There’s a rough patch from the 16th through the 20th where the swell drops under 3ft and the wind is cross or onshore – five days of basically nothing worth paddling out for.
Keep your eye on the 28th. It’s the most powerful, cleanest day on offer. Not perfect, but it’s the one.

Information about the Tarantulas Surf forecast
The above surf forecast table for Tarantulas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tarantulas can be found by selecting the local surf guide option on the grey menu. Our Tarantulas 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 (Tarantulas) 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 Tarantulas 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.
Tarantulas is 16 km (10 miles) from Lompoc. If you plan a vacation in Santa Barbara, look for hotels and other accommodation in Lompoc. Lompoc has rooms for a wide range of budgets as well as car hire and transport links.
