Windward-Oʻahu local beach in the Kāneʻohe Bay area — Surfrider BWTF community testing
Kaimalino is the local beach on windward Oʻahu's Kāneʻohe Bay coast — quieter than the main Kāneʻohe waterfront, frequented by residents. The latest Surfrider BWTF sample (2026-04-19) measured 41 MPN/100mL — within the 130 BAV threshold. The Hawaii DOH does not routinely test this beach.
Kaimalino sits within the larger Kāneʻohe Bay system, sheltered behind the bay's barrier reef. Recent BWTF reading was 41 MPN/100mL — within the 130 BAV threshold but at the lower-middle of the windward-Oʻahu range.
The Kāneʻohe Bay watershed includes multiple streams that elevate readings after rain. Kaimalino's relatively local sub-area has been less affected than the bay's southern flank near Heʻeia, but the same overall windward pattern applies.
Wait 72 hours after rain. The reef-protected geometry means this beach is calmer than open-coast windward spots, but flushing is also slower.
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.
Sandy entry from the central area. Reef-sheltered lagoon — calm year-round. Watch for sea urchins on the rocky margins.
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.
Windward Oʻahu's Kāneʻohe area. Limited roadside parking. About 25 minutes from Honolulu via H-3.
