What to expect for water quality, rainfall, and ocean conditions
Wailea Beach has one of the lowest advisory rates in Hawaii. The dry climate and lack of stream discharge mean water quality is consistently excellent.
June is ideal at Wailea: dry, warm, with calm south-shore conditions. Water quality is consistently excellent. Summer tourism begins increasing but the beach is never as crowded as Waikiki.
Summer occasionally brings south swells to Wailea, which can create larger-than-usual surf for this typically calm beach. Water temperature is warm (79-80°F). Check surf reports for unusual south-swell events.
High. Summer is peak family travel season with school holidays. Beaches are busy from mid-morning through sunset.
The Hawaii Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain. In june, rainfall is less frequent but individual storms can still produce contaminated runoff.
