Local Knowledge & Surf Guide

Local Knowledge

Grandma's in Maui is a fairly exposed reef break with fairly consistent surf. Summer is the best time of year to catch waves here. When it's working, conditions are best when a southwest swell pairs with offshore winds from the northeast. This spot is likely to be crowded if the surf is working. While it's a dependable location, the month of June tends to offer the best chance for consistent, clean waves.
