Best Time to Visit Hawaiʻi

Hawaii is a year-round destination, but late April, May, September, and October offer a particularly useful balance of weather and demand. The drier season generally runs May through October; the wetter season generally runs October through April. Windward and mountain areas receive more rain than many leeward resort coasts, and north-shore surf is typically larger in winter. Learn more about Hawaii weather.

To avoid the largest crowds, look at May or mid-September through early November, excluding Thanksgiving. Late April can also work after spring-break and Easter travel subsides. Demand varies by island and event, so check the current hotel chart and event calendar for your exact dates.

Start comparing Hawaii accommodations several months ahead. Book earlier for Christmas and New Year's, spring break, summer holidays, or a specific high-demand resort. Flexible travelers can compare refundable reservations as rates change; those needing a particular room type or island itinerary should prioritize availability over waiting for a last-minute discount.

Hawaii airfares vary by origin, route, day of week, airline capacity, and holidays. Begin tracking fares a few months ahead and book when the schedule and total price work for you. Holiday travelers should act earlier because desirable nonstop flights and schedules can disappear even when another fare remains available.

If you’re searching for the best rates when visiting Hawaii, we’d advise you to start your search for flights that arrive/depart in the middle of the week. Flying during the middle of the week will save you a lot of money, especially when flying from geographically further away. Generally, the most affordable rates for both flights and hotels in Hawaii will be primarily during the fall and somewhat so during the spring.

For accommodations, the months of September through November (sometimes into early December) offer the best hotel deals, again excluding Thanksgiving. In the spring, the best accommodation rates can be found from late March until early June (excluding the Easter holiday and Japan’s ‘Golden Week,’ in April).

For tours and activities, prioritize limited-capacity reservations over waiting for a speculative last-minute deal. If you want to bundle flights, hotels, and activities, Hawaii vacation packages can simplify comparison, but always check the total price, cancellation terms, and exactly what is included.

Hawaii offers snorkeling, diving, and swimming year-round, but there is no universally safe month. Summer often brings smaller surf to north-facing shores, while south swells can affect leeward beaches; winter reverses much of that pattern. Check the daily forecast, use lifeguarded beaches, and stay out when warning signs or lifeguards advise it.

In our opinion, Maui snorkeling is the best you'll find in the entire state, followed by snorkeling on the Big Island. Both islands offer great snorkeling locations largely protected from surf and tradewinds on the leeward side of each island.

Snow can fall on the highest Big Island summits during winter storms, but it is intermittent and should not be treated as a ski-resort experience. Access may close for ice, high winds, or other hazards. Check official road and weather notices before considering a visit to Maunakea, acclimate carefully to altitude, and never bypass a closure.

Cruise pricing and schedules depend on the ship, itinerary, embarkation port, and repositioning calendar. Compare the total fare and port time rather than relying on a single statewide "best" month. Winter itineraries may coincide with humpback season, but rougher ocean conditions and wet weather are also possible.

Humpback whales are generally present from November through April, with the peak whale-watching period from January through March according to NOAA's Hawaiian Islands Humpback Whale National Marine Sanctuary. Sightings are never guaranteed, and federal approach rules apply to boats, swimmers, and drones.

May is our preferred month for a destination wedding in Hawaii because it usually combines drier-season weather with lower demand than summer. No date is weather-proof. Choose a venue with a rain and wind backup, and remember that hurricane season runs June through November.

For many travelers, April, May, September, and October provide a useful balance of lower heat and drier-season conditions for hiking. That does not override a flash-flood warning, closure, permit requirement, or extreme heat. Check the official status of your chosen route, carry adequate water and sun protection, and expect Kauai trails in particular to become muddy or hazardous after rain.

Kīlauea's Puʻu ʻŌʻō eruption lasted from 1983 to 2018; later eruptions have occurred in separate episodes. There is no reliable month for seeing active lava. Check the U.S. Geological Survey and National Park Service shortly before visiting, stay on open routes, and see our current lava-viewing guide.

For stargazing, a clear night near the new moon generally provides darker skies than a full moon. You do not need summit access: lower-elevation visitor areas can provide excellent viewing with less altitude risk. Maunakea conditions can be cold and windy in any season, and closures take priority over an itinerary.

Fishing is available year-round, but target species, sea conditions, and regulations vary by island and season. Ask a licensed local charter what is realistically running during your dates, and confirm the cancellation policy for unsafe weather. Shore anglers should review current Division of Aquatic Resources rules and local access restrictions.

Winter brings the largest and most dangerous surf to many north- and west-facing shores; those conditions are for experienced surfers, not a general recommendation for visitors. Summer often brings smaller north-shore surf and more south swells. Beginners should use a reputable lesson at a protected location selected for that day's conditions.

For other water sports like paddleboarding, we like the spring and fall the best, but this again can be a year-round activity if you select the right location(s) based on the time of year you visit.

The best month for festivals depends on the event. The Merrie Monarch Festival is held in Hilo in the week after Easter. Oʻahu's Aloha Festivals commonly schedule major events in September. Other recurring festivals move from year to year, so confirm dates on the organizer's official calendar before booking a trip around one.

King Kamehameha Day is June 11, and Lei Day is May 1, with programming that varies by island and year. Check our Hawaii events page and then verify the final schedule with the host.
