The Lowdown
Alright, Rusty here with a look at what’s on the cards for the next couple of weeks.
Alright, so for this little pocket of paradise we’ve got one spot, Gili Air-Pertama, a reef break that only wakes up when the swell direction and wind play nice. To be honest, the first week and a half is a write-off for any decent paddle surfing. We’re looking at a real slow start with nothing worthwhile until the 13th of September, so about nine or ten days of flat or blown-out conditions.
Things finally get interesting on the morning of Sunday the 13th of September. The wind goes glassy out of the WNW with 3ft of groundswell from the SW, carrying a very long period of 18 seconds. That period is a real treat for a reef break like this – long lines, proper energy. The water is sitting at 81°, which is pretty average for this time of year. The combined energy is moderate at 370. This is the real standout window of the whole outlook.
We carry that goodness right into Monday the 14th of September. The afternoon session looks like the absolute pick with zero wind – dead glass – and a slightly bigger 3ft swell from the SW with a still-solid 16-second period. The energy reads at 489 and conditions will be smooth as silk. That’s your best bet for the entire forecast.
Tuesday the 15th and Wednesday the 16th of September keep the party going. Both mornings offer cross-offshore breezes and clean 3ft to 3ft SW swell. The afternoons are flat calm with glassy conditions. The energy stays moderate (412 to 483), so there’s plenty of push in the water for a longboard or a funboard. It’s a shame the spot is listed as inconsistent because when it turns on like this, it’s pure magic.
Things get a little more ordinary again from Thursday the 17th onward as the wind turns cross-on and the swell drops a touch. It’s still surfable, but that run from the 13th to the 16th is where you want to be.
Rusty, signing off.
