Righty-o, let's have a look at what's on the table. We've only got one spot in the mix here, Right and Left Side, a reef setup that's exposed to the north. It's inconsistent and usually has a few folks out, so don't expect to have it to yourself.

The water's sitting at 86°, which is just about what you'd expect for this time of year, no real shocker there.

Honestly, the next week and a half is a write-off. We're staring down the barrel of a massive pulse of energy – we're talking combined energy readings of 6205 to a whopping 14486, so there's plenty of power. But the wind is the enemy. We've got violent storm-force cross-shore and messy conditions, and big, dangerous, lumpy surf. The swell is over 8 ft for most of that first week, so this is strictly for experts only, and even then, the wind is making it a total mess. It's not worth paddling out for.

The first real glimmer of hope shows up on Sunday the 12th of July, in the afternoon. The wind drops to glassy, and we've got a clean 6 ft swell rolling in from the WNW with a long 14-second period – that's proper groundswell. The energy is still moderate (1307), and the wave comment says it's excellent for experienced surfers. Because it's a reef, that long period should wrap in nicely. After a week of chaos, that Sunday afternoon is the standout. It'll be clean, and with the inconsistent nature of the break, the sets will be worth the wait.

After that, Monday the 13th morning still has some clean 4 ft surf with a gentle offshore breeze, but it's noticeably smaller. From Tuesday the 14th onwards, the energy drops right off into the weak range (348 and below), the wind turns onshore or cross again, and the swell gets tiny. There's a little spike around Friday the 17th and Saturday the 18th, but the wind is onshore and messy, and the period is short (9 seconds), so it'll be crumbly and unappealing.

To wrap it up: if you can be patient and wait for that Sunday afternoon on the 12th, you'll be rewarded with some glassy, long-period reef waves. The rest of the 16-day run is mostly either dangerous and blown-out or flat and choppy.

Information about the Right and Left Side Surf forecast

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

Right and Left Side is 1 km (1 miles) from Agana. If you plan a holiday in Guam, look for hotels and other accommodation in Agana. Agana has rooms for a wide range of budgets as well as car hire and transport links.
