low confidenceStick to beaches with lifeguards and protected coves, like Hapuna or Carlsmith. Avoid windward shores where conditions can change quickly. If you’re new to snorkeling, Kahaluʻu’s shallow, reef-protected waters are ideal—but stay in designated areas to avoid strong currents. Check for bacteria advisories before entering the water.
Hapuna and Carlsmith Beach Parks are your best bets today. Both offer calm waters and lifeguards, but always supervise children closely. Bring sun protection—even on overcast days, UV rays can be strong. Keep an eye on weather updates, as conditions may deteriorate later in the week. Avoid beaches with murky water due to ongoing bacteria advisories.
While conditions are calm today, be mindful of the impending weather shift. If you’re planning a longer session, monitor surf reports closely. Avoid windward shores if you’re sensitive to choppy conditions. For snorkelers, Kahaluʻu’s reef remains a top spot for marine life, but be respectful of the delicate ecosystem and stay aware of currents outside the reef.
West-facing beaches like Hapuna and Kahaluʻu are reporting small to moderate surf (1-2 ft) with calm, clear waters. These conditions are ideal for swimming, snorkeling, and beginner-friendly water activities. However, the National Weather Service warns that southerly winds may increase rip current risks later in the week, especially on north- and windward-facing shores. Avoid entering the water if you see brown or murky water—ongoing sewage and bacteria advisories remain in effect for some areas.
Today’s weather is mostly dry and pleasant, with partly cloudy skies and temperatures in the mid-60s to high 60s. Trade winds are light (4-5 mph), keeping conditions comfortable for beachgoers. However, a significant pattern shift begins Tuesday, with heavy rain, thunderstorms, and potential flash flooding expected by midweek. The National Weather Service has declared Wednesday through Friday as First Alert Weather Days, urging residents and visitors to prepare for rapidly changing conditions.
Heavy rain and flash flooding risks return to the Big Island starting Tuesday, with the worst conditions expected Wednesday through Friday. The National Weather Service warns that saturated soils from March’s storms could lead to rapid runoff and dangerous conditions. Additionally, Kilauea Volcano is forecast to erupt between April 6 and April 14, which may affect air quality with hazardous volcanic gases. Visitors should monitor updates from the First Alert Weather Team and state health alerts before heading to the beach.
