The Lowdown
Alright surfers, Rusty here. Let’s break down the next couple of weeks at Tongo Reef.
Honestly, this isn’t the Tongo we dream about. The whole 16-day outlook is a bit of a flat spot. We’ve got a steady stream of small, mediocre surf with most of the wave energy sitting in that moderate range (between 413 and 1012). The problem is the swell direction. Tongo loves a solid S groundswell, but we’re getting a lot of SW and SSE windswell. That SSE stuff has a short period (8 seconds), so the waves will be weak and sectiony.
The first real chance for a decent wave comes Monday the 14th. That afternoon we get a SW groundswell around 4ft with a nice long 17-second period, and the combined energy hits a moderate 1012. It’s still just a "marginal" forecast, but the wind is a cross-off from the south, keeping the surface clean. This is the pick of the first week, but that’s not saying much. With that long period, expect longer waits between sets.
The rest of the week is much the same: waist-to-chest high (3ft to 5ft) SW groundswell, with periods dropping from 16 seconds down to 12, and a constant cross-off wind. The energy drops from 941 down to 563 by Thursday the 17th. It’s surfable, but every wave will require some effort.
The second week gets smaller. After the 22nd, we’re looking at waves between 3ft and 2ft, with energy dropping from 404 down to 287 by Thursday the 24th. The mornings of the 23rd and 24th get a "good surf conditions" tag, but it’s for clean, small waves. Winds are light, really glassy on the 24th. Perfect for a log or a fun mid-length. A new SW groundswell with a 19-second period shows up on the 25th with 650 energy, but at only 2ft, it’s mostly just a pulse on the buoy.
Tongo is an advanced reef break, and it can get crowded. This stretch just doesn't have the size or the right direction to fire. If you’re paddling out, your best bets are Monday afternoon the 14th for a bit more push, or the clean, calm mornings of the 23rd and 24th for a small-wave session.
Hang in there.
Rusty.

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.
