Bali Surf Season, Surfing Conditions Bali- Waterways Travel
Think of one of those international smorgasbord restaurants, all you can eat. That is what the Bukit Peninsula is like for surfers. Some of the foods are seasonal, and the season you pick may dictate your spot. From December through February the west/north-west trades blow offshore on the right-breaking reefs of the eastern coast. March and April are transition months into the dry season when winds are often light and variable, ocean conditions are glassy, and rain showers infrequent and scattered.
May through early October sees the dry season with little rain and consistent east/southeast winds blowing offshore along the west coast and that long series of lefts running down the Bukit Peninsula from Outside Corner to Kuta Beach.
May to October is also the best season for Grajagan, when the regular southeast trades meet up with Indian Ocean groundswells and create that fantasy surf.
October and November are again transitional months when the rain will start to return and the winds will go slack as they rotate back to northwest.
The weather is going to be warm to hot/humid year round; lows may get into the low/mid 70’s, and highs into the upper 80’s. The warmest and most humid months are December and January, and coolest, driest months are June and July. Water temperatures are mid 70’s to low 80’s following the same pattern as the air temperatures.
Indonesia and Bali is all about the south swells. Although south swells definitely occur year round, the real south swell season starts up some time in March/April and runs all the way through October, with the biggest swells often occurring May through September.
