The Lowdown

Alright, this is Rusty. Let's get into it.

We've got a mixed bag on the horizon for Tongo Reef. This is a reef setup, an advanced wave, and while it's fairly consistent, the next few days aren't going to give us much to work with. The early part of the week is looking a bit flat and messy. For the first few mornings, from Tuesday the 11th through Wednesday the 12th, we're seeing small swell around 3 ft to 4 ft, bumpy with a moderate cross-off breeze, and the scores are low. The combined swell energy is weak to moderate (808 down to 362), so it's really not offering much. You'd be scratching around for something rideable.

Things start to perk up a little from Thursday morning on the 13th. The swell bumps up to 4 ft to 4 ft, but the real story is the period jumping to 18 seconds—that's long-period groundswell. That brings a much better shape and more energy, with combined swell energy climbing to 1122 (moderate to strong). The wind stays cross-off, so it won't be perfect, but it gets a bit more interesting.

The standout window looks to be from Friday the 14th through Saturday morning the 15th. We’ve got a solid 5 ft of swell from the SW, with a 16-second groundswell period. The combined energy is peaking around 1400 (strong). The wind is cross-off at 12-16 mph, so the surface will be clean but not glassy. This is the best you're going to get in this stretch—consistent, powerful lines from the optimum S direction. After that, it drops back a notch for Sunday the 16th with slightly smaller swell.

Looking at the second week, Thursday the 20th is a little highlight with offshore wind in the morning. We'll see a clean 6 ft from the SSE, but the period drops to 10 seconds, so more of a mix of swell. The energy is moderate (822). The rest of that week holds in the 4 ft to 5 ft range with moderate breezes. By the final weekend, the 23rd and 24th, the swell gets small again down to 2 ft, though that long-period 18-second signal pops back in on the 23rd before fading. It’s there, but just too small.

Overall, if you're an advanced surfer, the best bet is to target the Thursday 13th through Saturday 15th period for the best combination of size and power. For the rest, you might just want to wait for the next pulse.

Rusty, signing off.

Information about the Tongo Reef Surf forecast

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