Best Time for a Kīlauea Volcano Tour

Wet season, dry season and the summit

The National Weather Service in Honolulu treats October to April as Hawaiʻi’s wet season and May to September as the dry season. On the Kona coast the difference hardly shows: Kona airport averages 13.4 inches of rain a year. The volcano sits on the wet side of the island at about 4,000 ft, and park headquarters averages 104.4 inches, about eight times as much. Hilo, which some circle-island tours pass through, averages 130.2 inches.

So you can leave a sunny Kona morning and reach a misty crater rim in any month; NPS describes the summit as rainy and chilly at any time of year.

Tours do not stop for ordinary rain. Wasabi Tours says its Twilight Volcano and Stargazing Tour runs rain or shine and gives no refund for closures or itinerary changes outside its control, and The Volcano Van operates in all weather. Storms are a different matter: in 2026 a March storm with ashfall, then Hurricane Lala in August and Hurricane Nolo in September, closed all or most of the park for stretches. Most areas reopened on 27 September 2026. Check the NPS alerts page in the week of your tour, and keep the free-cancellation window in mind: 24 hours before on the Viator tours here.

Temperatures: Kona versus the crater rim

Kona is warm all year and the summit is cool all year, so the season changes your packing list less than the altitude does.

Kona’s daytime highs run from about 81°F in January to about 87°F in August. NPS says the summit can be 12 to 15 degrees cooler than sea level, and nights are colder again, so a winter evening at the rim in wind and drizzle feels much cooler than the averages suggest. Several tours lend gear: the Wasabi twilight tour includes a rain and warm jacket, Hawaii Geo Tours provides coats, raincoats and umbrellas, and Kailani’s dinner tour includes a light jacket. Our guide on what to wear on a Kona volcano tour covers the rest.

Winter or summer for an evening tour

Sunset decides how the twilight tours feel. The Wasabi twilight tour picks up across Kona and the Kohala Coast between 9:30 and 10:30 a.m., spends about three hours in the park through the afternoon and twilight, and finishes with dinner and a stargazing stop. In November and December, with Kona sunsets around 5:45 p.m., darkness falls while you are still at the crater. In June and July, with sunsets after 7 p.m., the park visit is mostly in daylight and the darker sky comes later in the evening.

Whether to go by day or after dark is a separate decision, with its own trade-offs on visibility, return times and photography. Our Kīlauea day vs night tours page sets those out.

Frequently asked questions

What is the best month to visit Volcanoes National Park?

September, if you want the fewest people: it had the lowest air arrivals on Hawaiʻi Island in 2024 (117,302) and falls in the dry season. May, October and November are also quiet. No month improves your chance of seeing lava, since the eruption runs on its own schedule.

How often does Kīlauea erupt?

The current summit eruption has been episodic since 23 December 2024. Fountaining episodes usually last hours, with pauses of days to weeks between them; Episode 55 on 17 October 2026 came 53 days after Episode 54. As of 23 October 2026 it was paused, with a preliminary Episode 56 window of 29 October to 5 November.

Is Kīlauea open for tourists?

Yes. Hawaiʻi Volcanoes National Park is normally open 24 hours a day, and most areas along the Kīlauea summit reopened on 27 September 2026 after the hurricane closures. The Kīlauea Visitor Center is closed for renovation, with a temporary Welcome Center at Kilauea Military Camp open 9 a.m. to 4:45 p.m.

Does weather cancel volcano tours on the Big Island?

Rain usually does not. The tours on this site run in ordinary rain, and some say so in their listings. Park closures for storms, ash or hurricanes do change or cancel trips, as happened several times in 2026, so check the NPS alerts page and your tour’s cancellation window before the day.

Is the volcano visible in cloud or rain?

Sometimes. NPS notes that fog or rain can prevent eruption viewing altogether, and cloud often moves through the caldera, lifting and closing within the hour. Even on a clear day, glow depends on the eruption being active.
