Today's Surf Conditions at Periscopes
Best Surf Season & Climatology
Best Surf Season (May - September)
Periscopes hits its stride when the seasonal migration of the ITCZ flips Indonesia into the dry season. The northwest monsoon collapses, southeast trade winds build, and a sustained easterly flow out of the NE, ENE, E and ESE takes control of the coast. The Southern Hemisphere storm track also becomes highly active during this stretch, firing long-period SSW/SW groundswell up into the west-facing bight. Wave heights average 1.5-1.8m (5-6ft) with periods around 14 seconds, and the wind is ideal 81-96% of the time. This is the window when Periscopes is consistently glassy, powerful and firing.
