Windward-Oʻahu local beach in the Kāneʻohe Bay area — Surfrider BWTF community testing

Community Water Testing
The Hawai‘i Department of Health does not run routine bacteria-testing here. The readings below come from the Surfrider Foundation’s volunteer Blue Water Task Force, which fills coverage gaps DOH doesn’t reach.

Kaimalino is the local beach on windward Oʻahu's Kāneʻohe Bay coast — quieter than the main Kāneʻohe waterfront, frequented by residents. Check the Community Water Testing section for the sample date, result and full Surfrider report. A sample describes the water collected at that place and time; it does not establish today's water quality. Check the live DOH status above separately.

Why the Readings Run the Way They Do
Reef-protected, windward stream context

Kaimalino lies on windward Oʻahu's Kāneʻohe Bay coast, within the larger bay and watershed system. Reef shelter, streams and rainfall are part of the local geographic context.

A result from another Kāneʻohe Bay site does not establish conditions at Kaimalino. Read this site's dated community sample and current DOH advisories separately.

🌧️
After Rain — Wait Times
Light rain: 72 hours minimum, then visually verify the water has cleared.
Moderate rain: 4–7 days.
Storm or Kona low: wait until the water returns to clear blue-green visually. Can take 1–2+ weeks in extreme cases.
Testing Coverage

The Hawaii Department of Health does NOT routinely test Kaimalino. The community-tested readings on this page come from the Surfrider Foundation Blue Water Task Force, a volunteer-led monitoring program run by the Surfrider Oʻahu chapter.

BWTF samples Kaimalino biweekly using the IDEXX Enterolert method (MPN/100mL), and compares results against the same 130 Beach Action Value DOH uses statewide. See our overview of citizen water-quality testing in Hawaiʻi for the methodology and how BWTF data fits with DOH coverage.

Practical Notes
Where to Enter

Sandy entry from the central area. Reef-sheltered lagoon — calm year-round. Watch for sea urchins on the rocky margins.

When It's at Its Best

Quiet trade-wind mornings. Local-only feel. Better organized swim spots elsewhere — Kaimalino is more of a fish-and-relax beach than a swim destination.

Getting There

Windward Oʻahu's Kāneʻohe area. Limited roadside parking. About 25 minutes from Honolulu via H-3.
