Water quality, conditions, and what to know before you go
Makena Beach on the South Shore gets south swells primarily in summer (May-September). Winter conditions are typically calm. South swells can produce fun, manageable waves at many south-facing breaks.
Shore break varies with swell direction and size. Generally more moderate than north-shore breaks. Sand bottom entries are available at most south-shore spots.
Water quality varies with rainfall. Check the live advisory status above before surfing at Makena Beach. Avoid entering for 72 hours after heavy rain.
The Hawaii Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain. This applies to all ocean activities including surfing. Runoff carries bacteria from land into nearshore waters.
When conditions are clear, Makena Beach has great options for surfing. Check the water quality above, then book with confidence.
