When factoring weather, costs and low crowds, October is one of the best months to visit Hawaii. Let’s examine the details showing why October is an excellent month for a Hawaii vacation.
What’s Hawaii’s weather like in October?
After Hawaii’s warmest months of August and September, October temperatures cool down only slightly. Daytime high temperatures at most beach resorts average in the mid to upper 80s F. Nighttime temperatures only dip into the lower 70s F.
October rainfall levels in Hawaii are generally low — especially when compared to the wetter, winter months. However, in comparison to the drier, summer months, October rainfall levels are higher. Even though October rainfall levels are typically edging higher than the drier summer months, rain mostly falls at night in Hawaii.
Here are the average rainfall levels by island for the month of October:
Kauai – 3.82 inches – This measurement is based on Lihue’s averages per Weather.com. Lihue is located on the southeastern side of the island and is not as wet as the North Shore, but not as dry as the South Shore.
Oahu – 2.33 inches – This average is based on Honolulu’s rainfall per Weather.com, which will include Waikiki Beach. North Shore rainfall will be a little higher, while Ko Olina’s rainfall will be slightly lower.
Maui – 1.20 inches – This average is based on Kahului’s rainfall per Weather.com. Kahului is where Maui’s main airport is, but it’s not typically considered a resort area like Wailea, Lahaina, Kaanapali and Kapalua. Kahului’s rainfall tends to be a bit higher than all the resort areas, with the exception of Hana on east Maui.
Hawaii, the Big Island – 0.88 inches – This average is based on Kailua-Kona’s weather per Weather.com. Kailua-Kona is a popular resort area. Further north on the Kohala Coast, the weather tends to be even drier with only about 10 – 12 inches of rain for the entire year! Hilo, on the east side of Hawaii Island, is another story though, with an average of 9.77 inches of rainfall for October per Weather.com.
Lanai – 2.51 inches – This average is for Lanai City in Lanai’s upcountry/highlands, which tends to get much more rain that the island’s sunny, beach resort at Manele Bay. Data sourced from Weather.com.
Molokai – 1.39 inches – This average, per Weather.com, is for the airport just west of Kaunakakai town. Weather towards the east side will be rainier.
Generally, Hawaii’s ocean temperatures are the warmest in September and October, which make it more pleasant for swimming.
Tropical storms are rare events in Hawaii, but we feel we should note that October is during the official hurricane season. Learn more by reading these FAQs on Hawaii’s hurricane season.
