Conditions at Grupuk in August
August: The Most Frustrating Month
August represents the peak of the trade wind squeeze at Grupuk. Swell remains big - 1.8m average with a 14.3s period - and the SSW direction now contributes a remarkable 71% of the energy, with S another 21%. There are plenty of overhead waves in the 1.5-2.5m range, but ideal wind sits at just 1%. ESE and SE winds combine for over 90% of the wind distribution, mostly in the 10-30kph range. The result is bumpy, cross-onshore surf almost all month. If you find a sheltered corner, the raw material is epic; open beaches won't be pretty.
