The Lowdown
Right, let’s have a look at what’s in store for Cibratel over the next couple of weeks.
Honestly, the opening stretch is pretty grim. Friday afternoon kicks things off with a weak 2ft SSE swell and a cross-on wind, making for choppy, poor surf. The water is a touch warmer than normal at 70°, which is a little unusual for this time of year, but that’s small comfort when the waves are that ordinary.
Saturday morning cleans right up with glassy conditions and a light SW breeze, but the swell drops to 2ft and the period is short, so while the surface is clean, there’s barely any energy. You’ll catch a few knee-high dribblers if you’re keen. Sunday sees a bump in size to 4ft, but it’s cross-on and choppy again, so not worth getting excited about.
The standout window arrives early on Tuesday, 8th September. The morning brings clear skies and glassy conditions with a 6ft swell from the east. The combined energy is a solid 621 (moderate), and the offshore wind direction is swinging to WSW, which is good for Cibratel. That’s your best bet in the first week – clean, punchy, and a proper session for anyone who’s comfortable in overhead waves. The afternoon stays clean but the swell drops a bit.
After that, the surf fades again. Wednesday and Thursday are small and ordinary, with glassy mornings but no real power. The period stays around 8-11 seconds, so it’s mostly small and slow.
The second week brings a real spike. Saturday, 13th September, sees an 8ft S swell roll in, but the wind is cross-on and the combined energy is enormous at 2354 (strong to very strong). That’s a lot of power, but with the onshore wind, it’ll be a messy, heavy lineup – only for the experienced. The real gem is Monday, 14th September. The morning is glassy with a 6ft SE groundswell, period of 13 seconds, and combined energy of 1124. That’s proper, clean, long-period energy. The swell direction is from the SE, which is spot-on for Cibratel’s optimum. This is the best single session in the whole run – powerful, clean, and with that long period, the sets will have real push. The afternoon gets a little cross-on, so get on it early.
Tuesday, 15th September, is still fun with a 3ft SE swell and clean conditions in the morning, but the energy drops off after that. The rest of the run trails off into small, weak waves with the occasional glassy morning but no real size.
Summing up: don’t bother with the first few days. Aim for Tuesday morning, 8th September, for a good clean session, and then clear your schedule for Monday morning, 14th September – that’s the standout. After that, it’s back to dribblers.

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.
