Tongo Reef Surf Forecast and Surf Report

Right then, the whole 16-day window is all about Tongo Reef, and there ain’t a whole lot else to look at. The first few days are a write-off with tiny junky swell, but there’s a definite pulse of better energy building into the second half of August and carrying on into early September.

Alright, Monday the 24th of August is pretty grim. You’ve got a tiny 2ft SW groundswell pushing through, but it’s struggling to do much. The wind is a cross-off from the SSE at 12 to 16 mph, which keeps the surface clean enough, but the wave energy is only moderate at best (457). The water is a balmy 78°, which is a whopping 9° warmer than usual for this time of year – that’s very unusual, like stepping into a bath. Not worth paddling for.

Tuesday the 25th and Wednesday the 26th are equally flat. Swell drops further to 2ft and the period is all over the place. The combined energy falls way off (164 to 399), and with cross-off breezes hanging around, it’s just not doing anything for us. Thursday the 27th sees a little flicker back up to 3ft SW at 19 seconds, with the energy climbing back into moderate territory (694 to 837), but it’s still a marginal situation for this exposed reef.

Now we’re talking. Friday the 28th of August. The swell jumps up to a solid 6ft to 6ft from the SW, with a 16-second period. The combined energy hits strong, reaching 1734 (that's proper moderate-to-strong energy). The wind drops back to a gentle 9 mph from the SSE, staying cross-off. The wave comment still says "marginal," but this is the first real sign of life. That 6ft at a long period on Tongo Reef is going to have some real punch, but it’s a reef break and that’s strictly for advanced surfers. It’s the standout of this first week.

Saturday the 29th holds 5ft to 5ft SW, still with a solid 14-second period and light winds. Energy is still strong (1039). Sunday the 30th backs off a touch to 4ft, but the mix stays rideable.

Moving into the new week, Monday the 31st of August and Tuesday the 1st of September look average again, with the swell dropping back under 3ft. But hold on. Wednesday the 2nd of September afternoon sees another kick, with 4ft at a very long 19-second period, and the energy ticks over 1000 (1050). Then Thursday the 3rd of September is another real standout. You’re looking at 6ft SW at 17 seconds, and the combined energy surges to 1907, strong and meaty. Wind stays cross-off from the SSE at 9 to 12 mph. That’s a quality groundswell for Tongo Reef, pushing consistent lines. It’s beginner territory? No, not with those sizes and that reef, that’s for the experienced crew. And yeah, the crowds are listed as "sometimes," so you might have a few mates out, but nothing too nasty.

Friday the 4th of September holds steady at 5ft SW with a 15 to 16-second period and moderate cross-off wind. The energy stays well into the strong range (1420 to 1227). Saturday and Sunday (the 5th and 6th) start to drop off a little, and then Monday the 7th of September throws up a last hurrah: 5ft SW at 19 seconds pulling 1576-1819 of energy. That’s a very long period, so expect long lulls but clean, powerful waves on the takeoff.

Tuesday the 8th of September closes the window with 6ft to 6ft SW, 16-17 second period, and cross-off wind again.

A couple of things to note: the optimum swell direction for Tongo Reef is from the south, and this whole run is from the SW or SSW. That’s off-angle, but the reef is exposed, so it’ll still wrap in with decent shape, especially with those longer periods. The wind is consistently cross-off, which is a huge positive – the surface should be clean and lined up all through the best days.

So, in plain terms: ignore the first half of the first week. The best bets are Friday the 28th of August and Thursday the 3rd of September. Those are the two standouts for consistent, strong, long-period SW groundswell with clean cross-off winds. It’s a quality run for advanced reef chargers.
