What March feels like
March is when Waimea Canyon runs at its fullest and the roadside falls actually earn their pullouts. Spring-break crowds arrive mid-month; if the north-shore road closes with flooding, the south side is usually going about its business as normal.
Expect about 6 days with real rain — enough to notice, not enough to plan around. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 79° — bath-warm.
