Nusa dua Surf Forecast and Surf Report

G’day, I’m Rusty. We’ve got a 16-day stretch here at Nusa Dua, and to be honest, it’s a bit of a mixed bag. Right from the start, the swell’s there, but the wind’s not playing nice. The water temp’s sittin’ around 79.3°, which is pretty average for this time of year, so no surprises there.

Kicking off Saturday the 12th, we’ve got a clean-looking afternoon with some 4.3ft swell from the SSW, period around 14 seconds. The combined energy is solid at 1148 (moderate). Problem is, the wind’s blowin’ 12 mph onshore from the ESE, and the report says it’s marginal. Not worth paddlin’ out for, really.

Sunday the 13th through Tuesday the 15th, the swell bumps up a touch to 5.2ft–6.2ft, still from the SSW with long periods around 15–18 seconds. But the wind stays cross-onshore at 12–15 mph, and the energy is strong in the 2000s, but it’s all chopfest material. Scores are bottom-of-the-barrel, so you’re better off watching the horizon.

Wednesday the 16th to Friday the 18th, the swell drops back to 3.9ft–5.9ft, period coming down to 13–15 seconds. Energy is down to the 800–1400 range (moderate). Still cross-onshore wind, and the reports keep saying poor or marginal. The break is a reef setup, exposed to the SSW, which lines up nicely with the optimum direction, but the wind is ruinin’ the party.

Now, come Saturday the 20th, we start seein’ a little pulse. Morning session shows 5.2ft from the SSW, period 16 seconds, energy 1376 (moderate), and the wind’s onshore but lighter. Still only a marginal call, so don’t get too excited yet. Sunday the 21st, swell hangs around 5.6ft with 16-second periods, but the wind picks back up, keepin’ things messy.

Here’s where it gets interesting. Tuesday the 22nd morning, the period jumps to a very long 19 seconds, with 3.9ft swell from the SSW. The energy reads 1752 (moderate). That’s a proper groundswell, and for a reef like Nusa Dua, that long period could set up some beautiful lines. Wind is a lighter cross-onshore at 9 mph, so it’s still a little bumpy, but the potential is there. This is the first real standout – the kind of session where the sets are clean, the tide might be right, and you’ll be feelin’ that energy from deep water. Just remember, long-period swells at a reef can be a treat, but they also bring bigger gaps between sets, so patience is key.

From Wednesday the 23rd to Thursday the 24th, the swell builds to 7.2ft–7.5ft, periods 15–16 seconds, and energy is slammin’ in the 2000s (strong). Wind stays cross-onshore from the ESE at 12 mph. The size is gettin’ up there – over 6.6ft, so this is gettin’ into expert territory. Not a beginner’s wave, but for the skilled crew, the power is real. Still, the onshore wind is takin’ the edge off the quality.

Friday the 25th is the next real highlight. The swell holds at 6.9ft from the SSW, period 15 seconds, but the wind drops to a light 6 mph from the SE, and the energy spikes to 3898 (very strong). The report says it’s a 4 out of 10, and while that’s not a blinder, it’s the best we’ve seen. That lighter wind means cleaner faces, and for a reef, that’s gold. The wave state says “light cross-onshore with small wind ripples,” so it’ll be workable, with some real power behind it.

Saturday the 26th, the swell maxes out at 9.8ft in the morning, period 17 seconds, energy 4494 (very strong). Now, that’s a big boy swell – over 8.2ft, so it’s strictly for experts. Wind is onshore from the ESE at 9 mph, so it’s not perfect, but the sheer size and long period will produce some heavy, grinding reef waves for the brave. Afternoon drops to 8.2ft with similar energy. Sunday the 27th, the swell backs down to 6.6ft–7.2ft, periods 15–16 seconds, and the morning wind is still cross-onshore. The last session on Sunday afternoon shows the wind turnin’ onshore and lighter, with energy 1751 (moderate), so there’s a chance of a clean-up set or two as it winds down.

Overall, the best bet for a standout session is probably the morning of Tuesday the 22nd with that long 19-second groundswell – the kind of day that reminds you why you love the reef. And then Friday the 25th, with lighter winds and solid 6.9ft energy, is another one to circle.
