NOAA says humpbacks are generally seen in Hawaiʻi from November into spring, with the usual peak from January through March. Its sanctuary pages describe the spring endpoint differently: the boating guidance uses November–May, while the overview says whales are generally seen November–April. We treat May as a shoulder month when a sighting is possible but should not drive the trip.
We use this page to decide whether whales make the itinerary or remain a possible bonus. For island and viewing advice, continue to our Hawaiʻi whale watching guide after checking your month below.
Plan Around Whale Season
January through March: We would make whale watching part of the itinerary if it matters to you. This is the most dependable part of the season, though wildlife sightings are never guaranteed.
December and April: Both months fall within the general season but outside the usual peak. Keep whale watching in the plan if it matters to you, then choose a day with suitable ocean conditions.
November and May: These months sit at the edges of NOAA's broader boating-season guidance. We treat a sighting as a bonus rather than the reason to choose a tour or island.

Recommended Shore Viewing Spots
We picked these stops for open-ocean sightlines and public access. Conditions and access can change before your visit.
Whales are often seen from shore along the Kohala Coast during the active season. This is a region rather than one designated lookout, so choose a lawful public shoreline with an open horizon and give yourself time to scan.
This north-shore overlook is inside a national wildlife refuge. The refuge is currently closed for post-hurricane repairs and maintenance. Do not make a special-trip detour until you check the current refuge status.
We choose for ocean conditions rather than assuming whales follow a daily schedule. Calmer water makes the ride and horizon scanning easier; rough water or glare can hide a whale at any hour.
Federal Protection
Humpback whales are protected under the Marine Mammal Protection Act. In Hawaiʻi, federal law prohibits approaching within 100 yards by any means. The rule applies whether you are on the water, swimming, or using a drone. If a whale approaches, do not pursue or reposition for a closer view; follow the operator's instructions and NOAA's Hawaiʻi viewing guidance.

Mostly dry and breezy across Oʻahu today through Monday, with northeast winds holding steady and only light showers popping up on windward slopes. Leeward and resort areas stay dry.
Late Tuesday the pattern shifts. Winds drop and turn southerly, and tropical moisture moves in Wednesday through Friday—heavy rain will hit the islands, with potential flash flood conditions. Timing and intensity are still uncertain, but plan on wet weather. Ocean conditions will be choppy and elevated through Monday, then gradually ease midweek.
Hit the leeward beaches and snorkel sites Monday and Tuesday. Save indoor plans for Wednesday through Friday.

Steady northeast winds and mostly dry skies today through Monday. Light showers may pop up on windward slopes and in the mountains, but leeward and resort areas stay mostly dry.
Late Tuesday the pattern shifts. Winds drop and turn southerly, then deep tropical moisture moves in Wednesday through Friday. Heavy rain is likely statewide from late Wednesday onward, with potential flash flood conditions—timing and intensity are still uncertain. Ocean conditions are rough and choppy through Monday on windward shores due to strong winds, then gradually ease mid-week. A slightly larger northwest swell peaks Wednesday, and a west swell from a distant typhoon may bring moderate surf to west-facing Big Island shores by Thursday.
Leeward beaches and snorkeling work well Monday and Tuesday. Save indoor plans for Wednesday through Friday.

Steady northeast winds and mostly dry skies today through Monday, with only light showers scattered across windward slopes and the mountains. Leeward and resort areas stay dry. Ocean conditions are rough and choppy—a Small Craft Advisory is in effect through Monday evening.
Late Tuesday brings a shift. Winds drop and turn southerly, and tropical moisture moves in Wednesday through Friday. Plan for heavy rain and potential flash flooding from late Wednesday onward. Timing and intensity are still uncertain. Surf will ease mid-week, though a northwest swell peaks Wednesday and a distant typhoon may send moderate west swell to west-facing shores by Thursday.
Leeward beaches are your play Monday and Tuesday. Plan indoor activities starting Wednesday when the rain arrives.

Steady northeast winds are pushing cool, dry air across Kauaʻi right now. Light showers will pop up mainly on windward slopes and mountains through Monday, but leeward and resort areas stay mostly dry.
A pattern shift arrives late Tuesday. Winds will drop and turn southerly, and deep tropical moisture will move in Wednesday through Friday. Heavy rain is likely statewide from late Wednesday onward, with potential flash flood conditions—timing and intensity details are still uncertain. Surf will be choppy and elevated through Monday due to strong winds, then gradually ease mid-week before a slightly larger northwest swell peaks Wednesday.
Leeward beaches and snorkeling are best Monday and Tuesday. Plan indoor activities for Wednesday through Friday.
