The wet summer  season is offshore on Nusa Dua- Sanur east side of the island, with north-west winds usually from early December  to late March. This is the least crowded season for surfers. Although rain averages 2 inches a day in January and February, there can still be weeks of sunny weather with perfect surf.

Between seasons can be less predictable, but there are usually offshore waves somewhere on the island. The largest swells reliably arrive mid-winter form roaring forties weather fronts in the southern Indian ocean, although tropical cyclones during summer can send up a few days of solid swell.

Nusa Lembongan – (Dry Season – May to September)

Nusa Lembongan is the quintessential Balinese surf tour destination that you've dreamed about, away from the 24 hours of in ya face partying and sleepless nights of Kuta. Lembongan is a laid back destination where time - and busy roads - don't exist. It also happens to have some great surf spots. With surf breaks known as Lacerations and Razors you should know what to expect, though there are a couple of mellower reefs such as Playgrounds and Cheningan, a great longboard wave.

• Shipwrecks - The most famous and most surfed of all the waves on Nusa Lembongan, this right produces a good wall for manoeuvres and, depending on the tide, good tubes. Best at medium tide with a 4 to 6 foot swell, but can hold bigger swell on a good day.
• Lacerations - A powerful and very hollow right hander that can produce some of the best barrels around if the swell direction is right. Best at medium tide with swell of 3 to 8 ft. Breaks on very sharp live coral reef, hence the name!!
• Playgrounds - A right and a left with a soft coral bottom that are very easy and fun to surf, making it the favourite of inexperienced surfers and longboarders. Best with medium swell (3 to 6 ft) and medium or high tide.
