Right, let me break down this forecast in the old measurements for you. We're looking at one spot: Right and Left Side, a reef break that likes the north-west swell. It's an advanced wave and it's inconsistent, so you need to pick your moments. Water temp is about 85°F, right where it should be for this time of year.
The first part of the run, from Tuesday the 7th through to the 11th, is messy. Swell is running from 6ft to 8ft, with moderate to strong energy (1157 to 1972), but the wind is mostly cross-off or cross, meaning the surface won't be clean. The one bright spot is Thursday the 9th morning: the wind goes offshore from the SE at just 3 mph, the swell is a clean 6ft with a nice long 13-second period, and the energy is a solid 1162. That glassy look is your best early call, but on a reef, that's for experienced surfers only. Crowds are a possibility there.
Then it goes dead. From Monday the 13th afternoon all the way to Saturday the 19th morning, it's flat. Waves drop below 2ft, energy readings are tiny (down to 29), and the wind is onshore or cross-shore. That's a proper lull – not worth waxing the board.
But then – BAM. Sunday the 19th afternoon. A big 12ft west swell with the energy hitting a massive 3174. The wind is cross-off from the SW at 12 mph, keeping it clean for the experts. That's your first standout, but it's over 8ft, so you better know what you're doing.
Monday the 20th is the golden day. Swell holds at a solid 10ft from the west, energy is still huge at 2883, and the wind goes dead glassy in the afternoon – 3 mph from the south. Clean, powerful, long-period groundswell (12 seconds) tracking right onto the reef. That's the session to aim for. Experts only.
Tuesday the 21st morning is nearly as good: an 8ft west swell with a 12-second period and a clean offshore breeze from the ENE at 6 mph. Energy is 2114. Another standout morning.
Wednesday the 22nd rounds it out with a 7ft west swell and clean cross-off winds, energy at 1375. Still a very good wave.
So: the first week and a half is mostly a bust with that one clean slot on Thursday the 9th. Then it's flat for days. But from Sunday the 19th afternoon through Wednesday the 22nd, it's proper. The best is Monday the 20th with that big, glassy, clean 10ft west swell.

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.
