What to expect for water quality, rainfall, and ocean conditions
Sandy Beach has minimal bacteria risk due to the lack of streams or significant runoff sources. Even during the wet season, water quality is generally good. The primary hazard is the extremely dangerous shore break, not water quality.
February continues moderate rainfall at Sandy Beach. Water quality concerns are minimal due to the lack of stream discharge. Powerful shore break from south and east swells makes this one of Hawaii's most dangerous beaches for body surfing.
Winter swells from the east and northeast create powerful shore break. Sandy Beach is dangerous year-round but winter swells can produce unpredictable wave patterns. The beach is NOT for casual swimming in any season.
Moderate to high. Sandy Beach is popular with locals year-round. Winter brings spectators watching the powerful shore break. Tourist visitors are fewer since this is not a swimming beach.
The Hawaii Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain. In february, this is especially important as wet-season storms can produce heavy rainfall and significant runoff.
When conditions are clear, Sandy Beach has excellent ocean activities. Check the water quality above, then book with confidence.
