Kauai’s coastal waters remain unsafe due to storm runoff contamination. Stick to scenic drives, dry-land beach walks, or indoor activities.
Kauai’s island-wide brown-water advisory is still in effect after recent Kona Low storms contaminated coastal waters with runoff. The Hawaii Department of Health strongly advises against all ocean activities—swimming, surfing, and snorkeling are unsafe. While weather is sunny and dry, flash-flood risks linger in northern areas, and soils remain saturated. If you’re on the island, plan for scenic drives, dry-land beach walks, or indoor activities. Check local advisories before heading out, as conditions may change beach by beach.

low 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 and avoid water entry—brown-water 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 sunscreen and hats—sunny weather is expected, but UV levels are high.
All ocean activities are strongly discouraged due to brown-water advisories and hazardous runoff. 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—storm damage may still pose risks.
Kauai’s ocean conditions remain hazardous due to an island-wide brown-water advisory. The Hawaii Department of Health warns that storm runoff has contaminated coastal waters, posing serious health risks to swimmers and surfers. Hanalei Bay has moderate 3-4ft surf, but the water is unsafe for swimming. Poipu Beach Park’s south shore may have a shore break, and contamination levels are high. Lifeguards are advising against entering the water at all ocean beaches. Avoid all water activities until advisories are lifted.
Kauai’s weather is sunny with temperatures in the low 70s. Hanalei Bay and Poipu Beach Park both show 0% chance of rain, with light winds (2-3 mph) from the southeast. Soils remain saturated from recent heavy rain, increasing landslide risks in northern areas. Coastal areas may see light wind chop, but the primary concern is contamination from runoff.
Kauai’s storm recovery continues, with ocean safety advisories still in effect. The Hawaii Department of Health’s Clean Water Branch maintains an island-wide brown-water advisory due to storm runoff. Visitors are urged to avoid all ocean activities. A recent helicopter crash on Kalalau Beach underscores the risks of aerial tours during unstable weather. Check local updates for changes to advisories or closures. Additionally, the Lāhui Foundation is providing on-the-ground financial relief for flood victims in impacted communities.
