Kauai’s coastal waters are still contaminated from recent storms. Ocean activities remain hazardous. Opt for indoor or dry-land scenic options.
Kauai remains under an island-wide brown-water advisory due to contaminated runoff from the recent Kona Low storms. The Hawaii Department of Health warns that coastal waters are unsafe for swimming, surfing, or snorkeling. While weather conditions have improved slightly, flash-flood risks persist in northern areas, and soils remain saturated. If you’re on the island, plan for indoor activities or scenic drives—avoid unpaved roads, hiking trails, and all ocean entry. Check local advisories before heading out, as conditions may change beach by beach.

low confidenceAvoid all ocean activities today. Stick to indoor options like the Kauai Coffee Company, Kiahuna Sunrise Cafe, or the Grove Farm Homestead Museum. 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 Plantation Railway or a visit to the Kauai Museum. Pack rain gear—isolated showers are still possible, especially on the north shore.
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 3ft 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 partly cloudy to sunny with temperatures in the low 70s. Hanalei Bay is partly cloudy with a 0% chance of rain, while Poipu Beach Park is sunny with no rain expected. Winds are light to moderate (8-12 mph) from the east. 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. The Lāhui Foundation is providing financial relief to flood victims, with home visits ongoing through April 22. A preliminary NTSB report was released on a deadly Kauai helicopter crash last month, describing 'escalating vibrations' before the incident. Check local updates for changes to advisories or closures.
