With the Brown Water Advisory lifted, Kauai's beaches are open for dry-land activities. Ocean conditions vary-Hanalei Bay's surf is unusually high for summer.
Kauai's **island-wide Brown Water Advisory has been lifted**, but ocean conditions remain mixed. Sunny skies and light winds (1.8-2 mph) make today ideal for scenic beach walks, wildlife viewing, and dry-land exploration. **Hanalei Bay (North Shore) reports unusually high surf for May**-experienced surfers only-while Poipu Beach Park (South Shore) has 4.5ft waves, which are more typical for this season. Stick to designated swimming areas, avoid strong currents, and check with lifeguards before entering the water. The Waimea Wastewater Treatment Plant spill advisory remains localized and does not affect most beaches.

medium confidence**Avoid Hanalei Bay**-its surf is unusually high for May and unsafe for beginners. Stick to calmer south shore beaches like Poipu or Salt Pond. Always check with lifeguards before entering the water, and avoid areas with strong currents or shorebreak. Pack sun protection and water for dry-land activities.
**Poipu Beach Park and Lydgate Pond are your safest options** for swimming. Keep kids in designated areas and supervise them closely. Avoid Hanalei Bay due to strong surf and currents. Wildlife sightings (monk seals, turtles) are common-observe from a distance and follow posted guidelines.
**Hanalei Bay's surf is unusually high for summer**-proceed with caution due to strong currents. Poipu's south side may have a strong shorebreak-check conditions with lifeguards first. Avoid the Waimea area due to the localized sewage spill advisory. Always prioritize safety and respect wildlife closures.

Coastal areas may see light wind chop, but overall conditions are calm. Overcast skies are unlikely, so sun protection is recommended for beachgoers.
No Kauai-specific ocean advisories or closures were reported today, but **two unrelated crime stories from Oahu** and a **Cinco de Mayo taco feature** made headlines. For local events, check out **Red Dress Day in Hilo** (May 5), honoring missing and murdered Indigenous women. While not Kauai-specific, it's a reminder to stay informed about community events across the islands.
