Conditions at Nusa Dua in July
July: Peak Swell, Peak Frustration
July is the statistical peak of both swell and onshore wind. Average height reaches 7-8ft (2.1-2.4m) at 14.4s, with S and SSW combining for nearly 70% of the energy. But ideal wind is 1%, and the wind rose is an ESE/SE lock: 59.7% ESE and 29.7% SE. The sheer size and period guarantee power, yet the constant 20-30kph onshore flow makes Nusa Dua a battle. Water temp cools to 27.0°C, air to 25.8°C, and there is almost no rain (1.0mm/day). Unless you have a sheltered reef in mind, July is better for chasing other parts of the island.
