Question 1

Is it safe to swim at Makena Beach (Big Beach)?

Accepted Answer

From a water quality standpoint, Makena Beach has a Low bacteria risk rating (1 out of 5). It is an open-ocean beach with no streams, storm drains, or development nearby. South Maui's dry climate means less rain-driven runoff. However, Big Beach is known for powerful shore break that causes frequent injuries. The bacteria risk is very low, but respect the surf conditions.

Question 2

Why is Makena Beach water quality so good?

Accepted Answer

Makena benefits from several factors: it faces open ocean with strong wave action that flushes the water constantly, there are no streams or storm drains emptying onto the beach, no major development exists uphill to generate runoff, and South Maui is the driest part of the island so rain-driven contamination is rare. Hui O Ka Wai Ola water quality monitoring confirms that turbidity and nutrients drop significantly south of Kihei, with the Wailea-to-Makena corridor having the cleanest readings in South Maui.

Question 3

Is Big Beach dangerous?

Accepted Answer

but not because of water quality. Big Beach is famous for its powerful shore break that slams directly onto the sand. This causes more spinal injuries and broken bones than almost any other beach on Maui. The bacteria risk is very low, but the physical danger from the waves is real, especially for inexperienced swimmers. There are no lifeguards. If the waves look big, watch from the sand.

Question 4

What is Little Beach at Makena?

Accepted Answer

Little Beach (Pu'u Ola'i) is a smaller, clothing-optional beach just north of Big Beach, reached by a short trail over the lava rock point. It has a similar low bacteria risk profile since it shares the same open-ocean exposure and lack of runoff sources. Water quality is comparable to Big Beach.

Question 5

How does Makena Beach compare to other Maui beaches for water quality?

Accepted Answer

Makena is among the cleanest beaches on Maui. It shares a risk 1/5 rating with Wailea and Keawakapu nearby. By comparison, Hanakaoo Beach near Ka'anapali is rated 3/5 with recurring bacteria advisories, and Paia Bay on the North Shore is rated 3/5 due to stream mouth contamination. For water quality, the South Maui corridor from Wailea to Makena is your best bet on the island.

Question 6

Is Big Beach the same as Makena Beach?

Accepted Answer

Big Beach is the most commonly used name for Makena State Beach Park, also known as Oneloa Beach. Little Beach (Pu'u Ola'i) is a separate smaller beach just north, reached by a short trail over the lava rock point.

Question 7

What is the best time of year to swim at Makena Beach?

Accepted Answer

Summer (May through September) offers the best conditions at Makena Beach. Water quality historically rates at low bacteria levels year-round, but summer has the calmest surf, smallest shore break, and virtually no rainfall in South Maui. Winter swells can make Big Beach dangerous for inexperienced swimmers due to powerful shore break.

Question 8

How does Makena Beach compare to Wailea Beach for water quality?

Accepted Answer

Both Makena and Wailea Beach share a 1 out of 5 (Low) bacteria risk rating and sit along the same clean South Maui corridor with no stream inputs and dry climate. The main difference is surf conditions: Makena (Big Beach) has powerful shore break that causes frequent injuries, while Wailea has gentler waves and is generally calmer for swimming.

Question 9

Is Makena Beach affected by the Kona Low storms?

Accepted Answer

Major storms like the March 2026 Kona Low can generate brown water advisories that affect all Maui beaches, including Makena. However, because Makena has no streams or storm drains, it typically recovers in 24 to 48 hours compared to 72 or more hours for stream-mouth beaches like Hanalei Bay or Kailua Beach. Always follow the 72-hour rain rule after major storms.
