medium confidenceAvoid all ocean activities today. Stick to dry-land options like scenic drives along the Kuhio Highway or visiting shops in Hanalei. If you visit a beach, stay on the sand-contamination advisories mean high bacteria levels. Check the Hawaii Department of Health's Clean Water Branch for updates before planning any water activities.
Keep kids out of the water entirely. Ocean beaches and ponds are unsafe due to contamination. Opt for indoor activities like the Kauai Coffee Company or the Grove Farm Homestead Museum. Pack light rain gear-patchy showers are possible, but dry spells may allow for beach walks.
All ocean activities are strongly discouraged due to contamination advisories. Even if surf conditions look manageable, the health risks outweigh the benefits. Stick to dry-land activities or wait for advisories to lift. Avoid hiking trails like Kalalau-recent rain may have caused unstable conditions.
