The Lowdown

Alright, let’s get into it. The next couple of weeks are a mixed bag here at Cibratel. There’s a rough start, a few bright windows, and one standout day that’s worth circling on the calendar. The water is running much warmer than normal for this time of year, coming in at 22°, so you might not need the thickest rubber.

We kick off the period with nothing much going on. Monday 31 August is a write-off with tiny, disorganised waves and a risk of thunderstorms. The swell energy is weak (47) and the wind is cross-onshore. Tuesday 1st September is a little better with a clean offshore blowing in the morning, but the swell is still small at 2 ft from the south, with a short period of 7 seconds. It’s surfable but ordinary.

Wednesday 2 September sees a jump in size to 5 ft from the SSE, but it’s cross-onshore in the morning and onshore in the afternoon, so conditions are poor. The energy is moderate (452) but the wind kills it.

The real hope comes on Thursday 3 September. The early morning session is the pick: glassy conditions, 3 ft of SSE swell with a nice long period of 11 seconds. That’s proper groundswell energy, and the combined energy is moderate (203). The waves will be well-shaped, with longer gaps between sets. This is a good window for intermediate surfers who want clean, organised lines. The wind is dead calm, so it’s going to be silky smooth.

Friday 4 September also has a glassy start, but the swell drops to 2 ft and the energy fades (119). It’s clean but small. The rest of the weekend and into the following week is a tough stretch. From Saturday 5 through to Wednesday 9 September, the swell stays small, the wind is mostly onshore or cross-onshore, and the conditions are poor. A lot of those days are best skipped.

Now, here’s the standout. Thursday 10 September has a seriously good afternoon. The swell builds to 6 ft from the ESE, with a period of 8 seconds, and the combined energy jumps to a strong 689. The wind is glassy from the east, so the waves will be clean and punchy. This is the best session on offer in the whole 16-day window. It’s a bit too big for beginners, but for experienced surfers it’s going to be firing. The swell direction is a little off the optimum SE, but the size and glassy conditions more than make up for it.

From Friday 11 September onward, the swell drops back and the wind turns messy. There are a few more glassy mornings around Sunday 13 and Monday 14 September, but the waves are small and inconsistent. The energy is weak to moderate. The morning of Monday 14 September looks clean with 3 ft of SSE swell at 10 seconds, but it’s not a big standout.

Tuesday 15 September has a nice clean morning with a cross-offshore wind, 4 ft of SSE swell, and a long period of 11 seconds. The energy is strong (374) and the waves should have good shape. The afternoon, however, gets ruined by heavy rain and a cross-shore wind.

Overall, the best bet is Thursday 10 September afternoon. If you can only paddle out once, make it then. The rest of the period is hit or miss, but there are a few clean mornings if you’re patient.

Information about the Cibratel Surf forecast

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