Every lifeguard-staffed beach on Maui with water quality data
The gold standard for family beaches on Maui. Lifeguards, restrooms, showers, playground, and ample parking. Gentle shore break. South Maui dry climate keeps water quality consistently high.
Wide sandy beach with lifeguard tower, restrooms, and showers. Similar conditions to Kamaole II but without the playground. Good snorkeling at the rocky south end on calm days.
Lifeguard tower with a large grassy park area behind the beach. Great for families who want beach and park activities. Restrooms and showers available. Similar water quality to other Kamaole parks.
A beautiful crescent beach in Kapalua with lifeguards. The north end is calmer. Can have strong shore break, especially in winter. Lifeguards are particularly important here due to variable conditions. Restrooms, showers, picnic tables.
Large north shore beach with lifeguards. Conditions can be rougher than south and west Maui. Good for experienced swimmers on calm days. Baby Beach section at the west end has calmer water. Restrooms and parking available.
Maui's ocean conditions can change rapidly. Beaches that appear calm in the morning can develop dangerous shore break by afternoon. Rip currents can form without obvious visual cues. Lifeguards are trained to identify these hazards and warn swimmers before dangerous conditions develop. They rescue hundreds of swimmers each year on Maui.
For families with children, lifeguards provide an essential safety net. Even attentive parents can miss developing hazards. Lifeguards have the training and vantage point to spot danger before it becomes an emergency. Choose a lifeguarded beach whenever possible, especially with young children.
Lifeguard presence does not guarantee clean water. Bacteria levels can spike after rainfall at any beach. However, lifeguards can often provide information about recent conditions and may be aware of DOH advisories. They can advise you on where to swim and what to watch for.
South Maui's Kamaole Beach Parks have the best combination of lifeguards and consistently good water quality. The dry Kihei climate means rain-driven bacteria events are infrequent. North shore beaches like Baldwin receive more rainfall. Always check DOH advisories independently before swimming with children.
Maui County operates fewer lifeguard towers than Oahu's city system. Coverage is concentrated at the most popular swimming beaches. Many beautiful Maui beaches, including some of the most famous (Baby Beach, Napili Bay, Ulua Beach), do not have lifeguards. When swimming at unguarded beaches, extra caution is essential.
Lifeguard hours are typically 8 AM to 4:30 PM daily, but hours can vary by location and season. Always confirm when you arrive. If the tower is empty, treat the beach as unguarded. After hours, no lifeguard coverage is available at any Maui beach.

The 72-hour rule is the standard guideline from the Hawaii Department of Health: avoid swimming for at least 72 hours after heavy rain stops, especially near stream mouths, canal outlets, and areas with brown or discolored water. This applies to all beaches across all islands.
Bacteria from urban runoff, agricultural land, and aging cesspool systems enters the ocean through streams and storm drains. Hawaii has approximately 88,000 cesspools — more than any other state — many of which leak untreated sewage into groundwater that eventually reaches the coast. Beaches near known cesspool contamination areas carry higher risk, particularly after rainfall.

Safe to Swim Hawaii aggregates water quality data from six independent sources to provide broader coverage than any single agency. Our sources include the Hawaii Department of Health Clean Water Branch (beach advisories and bacteria testing), USGS National Water Information System (25 stream monitoring stations across all islands), NOAA CO-OPS (tide levels and water temperature), NDBC (wave buoys and ocean conditions), NWS Honolulu (weather and marine alerts), and City & County of Honolulu Environmental Services (Kailua Bay water testing and spill reports).
Historical bacteria risk ratings on this site are based on DOH testing data, Surfrider Foundation monitoring, geographic analysis (stream proximity, cesspool contamination areas, coastal development), and advisory frequency. These are historical assessments, not live measurements. Always check the live advisory status at the top of each page and verify conditions with the Hawaii DOH Clean Water Branch before entering the water.
