The Lowdown

Hey, it's Rusty. Let's talk Tullan Strand. Water temp is about 61°F, which feels a touch warmer than usual for this time of year.

The next couple of weeks are a mixed bag. Early on, we've got onshore winds messing things up. Saturday the 12th starts with a 7ft west swell but the wind is crossed up and lumpy. The energy is moderate at 1233. That afternoon, the wind drops but stays cross-onshore for a choppy 6ft wave. Not great.

Sunday the 13th is where it gets interesting. The morning goes glassy with a light south wind, and a clean 4ft WNW swell rolls in. Energy is light at 279, but with those glassy conditions, it'll be a fun, small-wave session. Afternoon stays clean with a light cross-off, but the swell drops to 3ft.

Monday the 14th is small and ordinary. A 2ft west swell with a weak 79 energy reading. You can surf it, but you'll be scratching. The afternoon picks up to 3ft with a longer period, but nothing special.

Then the wind turns nasty from Tuesday the 15th through the weekend. Strong cross-onshore winds, lumpy chop, and building swell get torn apart. Tuesday afternoon sees a 5ft WNW swell with 19 mph onshore wind – forget it. Thursday the 17th has a 7ft west swell with 19 mph cross-on winds. Energy is climbing into the 900s and 1500s (moderate to strong), but the wind is ruining it. Friday the 18th teases with a 8ft WNW groundswell and a 13-second period, but that cross-shore chop makes it marginal.

Saturday the 19th and Sunday the 20th are a washout. Strong onshore winds, thunderstorms, and rain. The swell is big – 10ft to 12ft – but it's a mess. Kite surfers might dig it, but for paddle surfing, it's a no-go.

Now, here's the standout. Monday the 21st of September. The morning brings a 13ft west swell with a long 13-second period and a gentle cross-shore breeze. The energy is massive at 5528 (very strong). This is serious groundswell. The wind is light enough for some clean faces. That said, 13ft is big – experts only. The long period means long lulls but powerful sets. Tullan is exposed to the west, so it'll be handling it. Be aware that a long-period west swell can be a bit straight at a beach break, but with that much juice, there will be waves.

Tuesday the 22nd offers a chance to clean up with a 7ft WNW swell and a light cross-off breeze. Energy is 1072 (moderate) and conditions are clean.

Wednesday the 23rd and Thursday the 24th are also looking good. Wednesday morning has a 5ft west swell with a gentle offshore SSE wind – clean and fun. By Thursday morning, the swell bumps up to 7ft from the WNW with a moderate offshore breeze. Energy is 898 (moderate) and conditions are clean. This is another strong option if you want something more manageable than the 13ft Monday.

The last few days fade out with onshore winds and building swell, so aim for the 21st to the 24th.

Best bet: Monday the 21st for the big, powerful groundswell if you've got the skills, and Thursday the 24th for a cleaner, slightly smaller day. Tullan can get crowded when it's good, so expect company.

Rusty, signing off.

Information about the Tullan Strand Surf forecast

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