Highest average quality score on the Big Island: 89.4/100. Five tours — fewer things, done extremely well. Dolphin encounters, food tours, and sunset sails off Kona.
One of the strongest sailing operations on the Kona Coast. 14 tours averaging 87.3/100 — catamaran snorkel, dolphin watches, and food-paired sunset sails.
One of the most recognized names on the Kona Coast. 12 experiences at 82.5/100. Excellent flagship offerings with some lower-scoring seasonal tours pulling the average.
The Big Island's premier land-based operator. Nine tours accessing places most visitors can't reach on their own — volcano hikes, birdwatching, waterfall treks at 79.1/100.
Operates from Waimea on the northern Kohala Coast — away from the Kona harbor crowds. Access to quieter reef systems along the northern coastline. 10 tours at 77.0/100.
Solid mid-range operation out of Kailua-Kona. 12 tours covering dolphins, scuba, snorkel, and whale watches at 76.8/100. Wide ocean activity coverage.
The Big Island's deep-water specialist. 21 tours with wide scoring spread — but the top end is genuinely world-class diving. 76.3/100 average across the full catalog.
Largest operator on the Big Island by volume — 32 tours from scuba to kayaking to deep-sea fishing. Hilo-based, 74.0/100 reflects that breadth.
Land-based operator focused on volcano excursions and Big Island sightseeing. 14 tours at 71.1/100, weighted toward group and private versions of core itineraries.

Dry conditions on Oʻahu today, with breezy wind in exposed areas. Drier weather continues through Wednesday as moisture clears out.

East-facing shores stay rough through the weekend. Winds remain breezy through Sunday, easing slightly Monday and Tuesday before picking up again Wednesday. A Small Craft Advisory is active through Monday morning for most coastal waters due to wind and sea state. Scattered showers arrive Thursday into Friday.
