The Lowdown
Alright folks, Rusty here. Let's paddle out and see what's on the menu for the next couple of weeks.
Looks like we're in for a bit of a slow start, but there's some promise on the horizon. The first few days are really just ankle-snappers, but don't write the whole period off just yet.
Alright, first up, we're looking at Big Beach. This spot is a very consistent beginner-friendly break, and it's fairly exposed to the swell. Water temp is sitting at 80.2°, which is about average for this time of year, so no surprises there.
The action kicks off on Friday, July 31st, with a tiny 2ft swell from the SW. It's a long-period groundswell at 15 seconds, but the energy is only moderate at 297. The wind is a cross-offshore breeze at 16 mph, which will keep things clean, but honestly, it's marginal. The combined energy is weak, and the score is low. It's surfable if you're desperate, but it's not worth getting excited about.
Saturday, August 1st, is more of the same. The swell drops to 2ft from the SSW, but the wind turns offshore in the morning and afternoon, which is a major positive for clean faces. Still, at that size, you're looking at knee-high waves at best. The energy is moderate (174 and 162), but it's just not enough.
Sunday the 2nd sees the swell drop further to 1.3ft. The combined energy plummets to 90 and 40, which is weak. The wind is cross-offshore in the morning and offshore in the afternoon, but the waves are so small it's barely a paddle. This is a write-off.
Monday the 3rd through Thursday the 7th is a long stretch of tiny, 1.3ft swell. The energy is mostly in the weak to moderate range (40 to 165), and the wind is generally offshore or light, which is a tease. You'll get clean, glassy conditions, but with waves that size, you'll be floating more than surfing. It's a few days of flatness for sure.
Now, here's where it gets interesting. Saturday, August 8th is the first real standout. The swell is still only 1.3ft, but it's a very long-period groundswell from the SSW at 18 seconds. The energy jumps to strong at 269 (that's a three-digit figure). The wind is light offshore from the ENE in the morning, so the morning session will be clean and glassy. This is the kind of day where a longboard will be your best friend. It's small, but the quality should be there.
Sunday, August 9th is the best of the bunch. The swell picks up to 1.6ft in the morning from the S, and then jumps to 2.3ft from the SSW in the afternoon. The period is a very long 18 seconds. The combined energy is strong, hitting 300 in the morning and a very strong 453 in the afternoon. The wind is offshore in the morning and light offshore in the afternoon. This is the day to be in the water. The waves will be long, clean, and have real push for their size. The optimum swell direction is from the SSW, and that's exactly what we're getting. This is your best bet.
Monday, August 10th keeps the fun going. The swell builds to 3ft from the SSW, with a 16-second period and a very strong 536 energy reading. The wind is cross-offshore, which is still fine. It's a bit bigger and a bit more powerful, but still very manageable. The afternoon gets a bit messier as the wind picks up.
Tuesday, August 11th through Thursday, August 14th sees the swell holding in the 2.3ft to 3ft range, with strong energy (300 to 638). The wind stays cross-offshore or offshore, so the conditions will be clean. The waves are there, but the quality is a bit more mixed. The long period (14-18 seconds) is great for points and reefs, but at a beach break like Big Beach, it can sometimes be a bit too straight. Still, there will be waves.
The real standout for the second week is Wednesday, August 12th. The morning session sees a 2.3ft swell from the S, with a very long 18-second period and a very strong 609 energy reading. The wind is a gentle cross-offshore breeze. This is a solid, clean swell with plenty of energy. It's a bit more of a long-range call, so don't set your watch by it, but it looks promising.
The final few days, Friday, August 14th and Saturday, August 15th, see the swell drop off a bit to 2.6ft, but the direction shifts to the W. The wind picks up, turning into a fresh breeze, which will chop things up. The energy is still strong, but the quality will be poor. It's a bit of a fade-out.
So, to sum it up: the first week is a slow grind with tiny waves. The standout is undeniably Sunday, August 9th, with clean, offshore winds and a solid 2.3ft groundsw

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