The Lowdown
G’day crew, Rusty here. Let’s look at what’s coming up for Sanur. Honestly mate, this is a tough stretch. The whole 16-day window is a bit of a grind with only one break on offer, and it’s not exactly firing.
We start off with some size, but the conditions just aren’t there. On Sunday September 13th we’ve got solid 6ft to 6ft SSW swell with a very long 17-18 second period, packing strong energy (2108), but the wind is onshore from the SE at 12 mph, killing any chance of clean waves. The water temp is about average for this time of year, which is nice if you’re just floating around, but not much else to get excited about.
Through the week from Monday September 14th to Wednesday September 16th, the swell hangs in around 5ft to 6ft with that long 15-16 second period, but we’re stuck with onshore breezes and poor surf conditions – scores are a flat zero. It’s just messy out there.
Thursday September 17th and Friday September 18th see the swell looking similar, 6ft down to 5ft, but the wind finally drops off a bit to a gentle breeze Friday afternoon – still onshore – and we get a couple of marginal tags. The energy drops into the moderate range (around 896 – 759), so the power is fading.
Saturday September 19th is light winds and a small cross-onshore breeze, but with swell down to 4ft and only moderate energy (848 – 885), it’s not going to be memorable. Still marginal.
Here’s where we get a glimmer – Sunday September 20th morning sees 6ft SSW swell with a 16-second period pushing moderate-to-strong energy (1556) and light onshore wind. It’s still only a 2/10 rating, but it’s the best of a bad bunch in the first half. The wave quality is questionable due to tide and wind, but if you’re desperate, it’s the most promising session in the next week.
After that, it’s more of the same right through to late September – onshore winds, marginal or poor conditions, with swell building again. By Wednesday September 23rd we’ve got 7ft to 7ft SSW groundswell, long 16-second period, and energy pushing strong (2357 – 2612), but the wind is still onshore and the conditions are only marginal. That kind of size with those winds – messy and not worth a paddle. Thursday September 24th and Friday September 25th get even bigger, with 8ft SSW swell on Friday morning and energy at 3954 – very strong – but cross-onshore wind at 9 mph makes it choppy and only for experienced heads who don’t mind a battle.
The final weekend, Saturday September 27th and Sunday September 28th, sees the swell drop slightly but still solid at 7ft to 7ft with long 15-second period and strong energy (1894 – 1917), and the wind lightens up to a light cross-onshore breeze. Conditions are described as marginal with light cross-onshore ripples. It’s the most user-friendly window in the whole outlook, but still not clean.
Overall, this is a lean couple of weeks. The best bet is probably Sanur – Grand Hyatt (Sanur) on Sunday September 20th morning – swell direction is SSW, which is a long way off the optimal S direction for this reef, and with onshore wind it’s not going to be pretty, but it’s the one day that nudges closest to rideable. That long 16-second period will give it some push, but the onshore breeze and the wrong swell direction will keep it average.
If you’re a kite surfer, some of those bigger blustery days with 8ft swell and onshore wind at 9 mph could still be fun.
Keep patient, mates. It’s not a total write-off, but it’s close.
Rusty.
