Righto. Let’s have a look at what’s on the cards for Bali Bay (Glen Reef) over the next couple of weeks.

Alright, pull up a pew. We’ve got a bit of a slow start here, but don’t go anywhere, because the second half of the first week and into the second week is where it gets real interesting. The water temp is sitting about average for this time of year, so no surprises there.

The first few days are a bit of a write-off, to be honest. Friday the 3rd and Saturday the 4th have some swell, but the wind is messy, mostly cross or cross-off with a moderate breeze, and the energy is moderate (793, 331). It’s not going to be worth getting wet for. Sunday the 5th is a little better, with a clean 4ft from the W on a short period of 8 seconds, but still only a moderate breeze. It’s a pass.

Now, Monday the 6th is where things start to turn. We get a clean 5ft swell from the SW, period bumping up to 11 seconds, and the wind goes light with a slight air. The energy jumps to a solid 1307 – that’s moderate to strong. This is a good, fun size for intermediates, and it’s looking clean.

But the standout for the entire run, no question, is Tuesday the 7th morning. Glassy conditions, 6ft from the SW, a proper 12-second period, and a combined energy of 1242. That is a beautiful, clean, lined-up reef break. The wind is dead calm. This is the one to circle on the calendar. It’s going to be a ripper morning.

Wednesday the 8th morning stays glassy, but the swell pumps up to 8ft from the SW with a 13-second period and a massive energy reading of 3412. That’s big stuff. At that size, this break is getting into expert territory. Only go out if you’ve got the experience. It’ll be a beast.

Thursday the 9th stays solid, 8ft from the SW, 14-second period, with a clean cross-off wind. The energy is still very strong at 3163. This is still big and powerful. The quality remains high through Friday the 10th and Saturday the 11th, with clean 7ft and 6ft swells and long periods, all under light to gentle breezes. Consistency is very high here, so there will be waves.

Sunday the 12th morning brings another highlight: 7ft from the SSW, a very long 16-second period, and extreme energy at 2402. That’s a proper groundswell. Because this is a reef break, that long period will wrap in beautifully. Light cross-off wind. Another top-tier session.

Now, we hit a rough patch. Monday the 13th gets messy with a moderate nor'ly breeze, and the swell drops. Tuesday the 14th is a write-off with onshore wind and heavy rain – avoid it entirely. Wednesday the 15th through Thursday the 16th sees the swell go absolutely mental, 12ft to 15ft from the WSW and SW. The energy readings are extreme (3854 up to 8042). The forecast says it’s too big for this break, and I’d agree. That’s kite-surfing territory for this exposed reef.

After that big pulse drops, we get a killer finale. Friday the 17th morning is glassy, 10ft from the SSW with a 14-second period and energy of 3162. That’s still very big and only for experts, but clean as a whistle. Saturday the 18th morning brings it back down to a clean 6ft from the SSW, glassy, with a 12-second period and solid energy of 1043. A perfect way to finish the run on a high note.

So, the real standouts? Tuesday the 7th morning for that glassy intermediate perfection. And Sunday the 12th morning for the long-period groundswell. Get on them.

Rusty.

Information about the Bali Bay (Glen Reef) Surf forecast

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