Our Review: Hilo Ocean Adventures
Hilo Ocean Adventures is the largest tour operator on the Big Island by sheer volume — 32 tours covering everything from scuba diving to kayaking to deep-sea fishing to waterfall cruises. The average quality score of 74.0/100 reflects that breadth: the catalog includes premium guided experiences alongside basic gear rentals that pull the number down. The guided tours themselves are considerably stronger than the average suggests.
The top tier is impressive. The Beach Snorkel - Sea Turtle Lagoon and Black Sand Beach leads at 93/100, offering a guided snorkeling experience at one of Hilo's most unique coastal sites. Discover Scuba Diving and the 2 Tank Shore Dive at Leleiwi Beach both score 91/100 — Leleiwi is a protected bay with some of the best shore diving conditions on the island's east side. The Royal Humpback Whale Experience (87/100) is the only quality whale watch operating out of Hilo, which makes it essential for east-side visitors during season.
Their kayak program is a hidden strength. The Hilo Bay & Coconut Island Adventure and Wailoa River to King Kamehameha Statue Adventure both score 84/100, offering guided paddles through culturally significant waterways that most Kona-focused operators ignore entirely. The Myths & Legends Waterfall Adventure (81/100) kayak tour adds a waterfall component that plays to Hilo's rainy-side geography.
The Cliffs of Hawaiʻi Onomea Waterfall Cruise (82/100) is another unique offering — a boat tour along the dramatic Hamakua Coast that's impossible to replicate from the Kona side. The bottom of the catalog is populated with gear rentals (surfboards, kayaks, snorkel gear, SUP boards) that score in the 55-64 range, which is expected for rental-only products.
Who This Operator Is Best For
Anyone staying on the Big Island's east side. If you're in Hilo or visiting Hawaiʻi Volcanoes National Park, Hilo Ocean Adventures is essentially your only full-service ocean activities provider. Their guided kayak tours and shore dives at Leleiwi Beach are the standouts, and the waterfall cruise along the Hamakua Coast is something you can't get anywhere else on the island.

Heavy rain from the past day is clearing out tonight. You'll see scattered showers Friday morning—lighter and less frequent than what came through—then dry trade winds move in and stick around through at least the middle of next week.
Windward and upland areas will still catch occasional brief showers even as things dry out, but leeward sides turn partly cloudy to mostly clear. Moderate surf holds on south, north, and west-facing beaches through the weekend, close to warning strength. Winds stay gusty through Friday as the system pulls away, then ease once the trades lock in.
Beach days and snorkeling on leeward shores start looking good Saturday. Summit trips and exposed hikes are best waited until winds ease this weekend.

Heavy rain from the past 24 hours is ending tonight. You'll catch scattered showers through Friday morning—lighter and thinner than what just passed. Trade winds take over after Friday and hold steady through the middle of next week, bringing drier conditions and partly cloudy to mostly clear skies on the leeward side.
Windward areas will still see brief showers even as things dry out. Moderate surf hits south, north, and west-facing beaches through the weekend, close to warning levels on the south shore but not quite there. Gusty winds persist tonight and Friday, especially near mountains and exposed coasts, then ease once the trades settle.
Leeward beaches and snorkeling spots turn prime starting Saturday. Save the summit drive and ridge hikes for when winds ease this weekend.
