Fall

Molokini Crater tours in fall

The short answer Fall is a good time. September has the warmest water in NOAA's table, and November brings the first humpback whales. Hurricane season runs to Nov 30, so read the forecast and your operator's policy.

Fall works for a Molokini trip. September has the warmest water of the year in NOAA's table, October is where the wind pattern starts to change, and by November the first humpbacks are due.

What the numbers say

NOAA's monthly averages at Kahului Harbor, on Maui's north shore, are 80.7°F for September, 80.0°F for October and 78.3°F for November. Molokini is on the other side of the island, so treat these as a guide and not a reading.

Trade winds blow 80 to 95 percent of the time from May to September. From October to April that drops to 50 to 80 percent. That is a lower share, so trade winds will be absent on more days. We found no source that says fall is calmer or quieter, so we won't claim it.

Time of day still matters more than the month, and most Molokini boats leave in the morning. The best month guide has the full-year table and the reason.

Whales in November

A November whale is possible, but the odds are lower than in February. Whale trips start later. Trilogy, for example, lists its Māʻalaea whale watch from Dec 15. Each operator sets its own whale dates, so check the trip page. The whale watch or snorkel guide has the season dates and the trade-off.

Storm season

NOAA's National Hurricane Center gives June 1 to November 30 as the Central Pacific hurricane season. That covers all of fall.

You can't plan around one storm weeks out. What you can do:

  • Check the forecast from the National Weather Service for Maui a few days before.
  • Read your operator's weather and cancellation terms before you pay. They differ, and we did not find a common rule.
  • Keep a flexible day in your schedule if you can.

Four Winds words its Molokini stop as weather permitting. The month guide compares operators' weather terms.

Families and couples

Pick the guide for your group, then check who is sailing on your dates.

For families, read the kids guide and compare boats with child fares. In fall, the thing to check is the start time: a 6:30 a.m. check-in is a hard morning for young children, so look at when each boat boards. Minimum ages differ by trip, and each operator sets its own. Ask also how the operator handles infants and toddlers, since fare cutoffs for young children vary from page to page. A larger boat with shade suits small children better than a bare raft deck; a raft suits a group that wants a smaller, more active trip.

For couples, read the couples guide. In fall, check whether drinks are included or extra on the trip page, and whether the boat is a larger catamaran or a raft. Both are listed in the trip comparison. Book the earliest departure your group can manage, and keep the afternoon free.

Booking in November

Thanksgiving week is its own case. See Thanksgiving and the holidays on Maui.
