Humpbacks are here November through April with the peak from January through March, and the sanctuary itself says you can see them from shore.
No agency published whale window is open in Hawaii todayEvery window below is the wording of the agency that publishes it, reproduced exactly, with a link. Where two agencies describe the same animal differently, both are shown.
November 1 to April 30
“Humpback whales are generally seen in Hawaii from November through April each year, with the peak season from January through March.”
Hawaiian Islands Humpback Whale National Marine Sanctuary
What you are looking for: A tall columnar blow, a small dorsal fin on a hump, and the black and white underside of the tail as it dives. The only large whale that routinely breaches clear of the water.
The sanctuary writes that "Each winter and spring approximately half of the north Pacific humpback whale population, representing thousands of animals, visit the waters around the Hawaiian Islands." No sanctuary or park page names individual lookouts in its own words, so none are listed here. The Sanctuary Ocean Count is the agency’s shore programme: NOAA runs it from shore on Oahu, Hawaii and Kauai, on the last Saturday of January, February and March.

The Hawaiian Islands Humpback Whale National Marine Sanctuary puts it in one sentence: "From November through April, visitors to the sanctuary can see whales from shore and at sea."
Hawaiian Islands Humpback Whale National Marine Sanctuary
No federal or state agency names a specific Hawaii shore lookout in its own words, so none is listed here; the agencies' own assessment of shore viewing on this coast is above.
Hawaiian Islands Humpback Whale National Marine Sanctuary
The last Saturday of January, February and March, from 8:00 am to 12:15 pm
The sanctuary describes it as a chance to "monitor humpback whales from the shores of Oahu, Hawaii and Kauai". It is a shore-based count, which is the same method NOAA uses to estimate gray whales on the other side of the ocean.
The recurrence rule is fixed; the specific Saturdays for a coming year are posted by the sanctuary closer to the time. Agency page
Approach distances differ by species and by region, and the differences are large enough that a number remembered from another coast can put you in breach of federal law. Below, the rule for each species that has a published season here, quoted from the agency that issues it.
“In Hawaii and Alaska, it is illegal to approach a humpback whale within 100 yards, by land or sea. It is also illegal to approach humpback whales in Hawaii within 1,000 feet (333 yards) by air.”
NOAA Fisheries, Humpback Whale: Resources
Note the phrase "by land or sea". NOAA states this rule two different ways on two of its own pages: the species resources page says "by land or sea", while its general viewing guidelines page frames the same 100 yards as a requirement on vessels. Outside Hawaii and Alaska the 100 yards is guidance rather than a humpback-specific law.
Never approach a whale to get a better view, and never put a drone over one. If an animal comes to you, the instruction from NOAA is to move away from it, slowly, not to hold position for a photograph.
The chart below counts research-grade public observations by month. It is not a season. It is a record of when somebody was standing in the right place with a camera and knew what they were looking at, and that depends at least as much on tourism and daylight as on whales. Winter is systematically under-counted everywhere on this coast for exactly that reason.
It earns its place because when it disagrees with the agency window, the disagreement usually has a cause worth understanding.
Reading the public observation record for Humpback whale in Hawaii…
Gray whales pass twice, southbound from December and northbound from mid-February, and California has more agency-named shore lookouts than any other state.
Agencies name shore sites hereThousands of gray whales pass mid-December to mid-January going south and from late March going north, and about 200 stay all summer.
Agencies name shore sites hereGray whales pass the outer coast in spring, and the inland waters hold killer whales under the strictest state approach law in the country.
Shore viewing is possible but agencies are cautiousThe summer feeding ground for the humpbacks that spend their winter in Hawaii, and the National Park Service says they feed within a mile of shore.
Shore viewing is possible but agencies are cautiousHumpbacks arrive in April and are in large numbers through the summer, and right whales fill Cape Cod Bay in late winter under a federal January to May shipping rule.
Shore viewing is possible but agencies are cautiousHumpbacks, finbacks and minkes feed in the Gulf of Maine through spring, summer and autumn, and the National Park Service says do not expect to see them from shore.
Agencies say do not expect to see whales from shoreHumpbacks are close to shore in summer and autumn in the New York Bight, and right whales are detected in spring and winter.
Agencies say do not expect to see whales from shoreThe only known calving ground on earth for the North Atlantic right whale, occupied from mid-November to mid-April.
Shore viewing is possible but agencies are cautiousThe southern half of the right whale calving ground, mid-November to mid-April, and the one state whose wildlife agency says the whales are often visible from the beach.
Shore viewing is possible but agencies are cautiousA winter state, unusually: humpbacks concentrate off the Virginia coast in January and February while New England is empty.
