Updates in  hr  min  s Forecast update imminent

Alright, Rusty here, let's talk about what’s coming up for Right and Left Side.

Right off the bat, Monday the 6th is a write-off. That storm-force wind – 59 mph cross-on with a 21ft swell – it’s a mess. The combined energy is insane (24156), but it’s not for surfing. That afternoon doesn't look any better, either. We’ve gotta wait it out.

Tuesday the 7th is cleaner but still not great. The swell drops to 5ft on Tuesday morning but the energy is weak (896), and the wind is cross-off. Not worth paddling out. By Tuesday afternoon we've got 10ft of W swell, but the wind is still cross-off and it’s just not coming together. The energy is moderate (2370), but the surf quality is marginal.

Wednesday the 8th stays in that same mediocre groove. 8ft swell, clean wind, but the wave quality is just questionable. It’s a bit too much size for the consistency this break offers.

Now, Thursday the 9th is where we finally see something. Thursday morning at Right and Left Side, we’ve got 10ft of W swell with a nice 13s period, light SSE offshore wind at 6 mph, and the combined energy is strong (3020). This is excellent surf for experienced surfers. The wave quality is there, clean conditions. This is the standout of the first week. The only catch is this break is inconsistent, so you gotta pick your moment. It’s a reef break that needs that North optimum swell direction, but the W swell is working well. Water temp is 85°, pretty normal for this time of year.

Friday the 10th and Saturday the 11th fade back into marginal conditions – the wind shifts around and makes things choppy. Sunday the 12th still has clean conditions early with a 6ft W swell, but it’s for the more experienced crew.

We hit a long, flat, poor stretch from Monday the 13th through to Thursday the 16th. The swell just bottoms out. By the 15th and 16th we’re looking at 1ft waves and weak energy – forget it.

Then, a promising sign for the second week. On Friday the 17th of July, it’s glassy in the morning with an 8ft W swell. The period is short (9s) but the wind is glass. This could be a nice window for the advanced surfers.

Saturday the 18th of July morning is the real long-range stand-out. Glassy conditions, 10ft W swell, and a moderate energy of 1616. Excellent conditions for those who know the break.

Finally, Sunday the 19th of July looks solid again. Both morning and afternoon have 10ft W swells with a 12s period, moderate offshore wind from the SE, and strong energy (2819). That’s clean, powerful, and all the way into the second week. It’s promising, but it’s still a long way off, so don't lock it in just yet.

So, the best of the lot is Thursday the 9th morning. After that, keep an eye on that Saturday the 18th and Sunday the 19th.

Rusty.

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.
