If you are considering an August vacation in Hawaii, you may be wondering if it’s a good time to visit the islands of Aloha. Let’s examine weather, costs, visitor statistics and more to help you decide if August is the best time for you to vacation in the Hawaiian Islands.
What’s Hawaii’s weather like in August?
August and September are two of the hottest months in Hawaii. August weather in the Hawaiian Islands can be described as very summer-like with lots of sunshine and warm temperatures. Daytime high temperatures at most beach resorts average in the mid to upper 80s F. Nighttime temperatures only dip into the 70s F.
August rainfall levels in Hawaii are generally low. August precipitation levels are only slightly higher than the lowest rainfall averages normally seen in June. Here are the average rainfall levels by island for the month of August:
Kauai – 2.13 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 – 0.93 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 – 0.5 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 – 0.67 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 9.85 inches of rainfall for August per Weather.com.
Lanai – 1.40 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 – 0.45 inches – This average, per Weather.com, is for the airport just west of Kaunakakai town. Weather towards the east side will be rainier.
June, July and August are three of Hawaii’s driest months. By August, the drier conditions tend to lessen the flow on some waterfalls. You should still be able to see waterfalls on the islands, however they may be less dramatic depending upon recent rainfall.
It’s worth mentioning that August and September are the “peak” months of the Pacific hurricane season. That being said, hurricanes are relatively rare events in Hawaii and we personally wouldn’t hesitate to book a trip to Hawaii in either August or September or any part of the official hurricane season.
Is August a popular time to visit Hawaii?
From our analysis of Hawaii Tourism Authority statistics, August is one of the top three months with the most visitors coming to the islands. The beginning of August is particularly busy time as August is the last month for summer vacations for families with children in school.
Is August an expensive time for a Hawaii vacation?
Per our Hawaii hotel rate analysis, August hotel rates start out being higher than average, but by the end of the month, rates lower to below average.
Predicting airfare is much more difficult. With August being a popular time to visit Hawaii — particularly in the first couple of weeks — it’s a fairly safe assumption that airfare will be higher than average. Towards the end of August, you are more likely to find an airfare bargain as compared to the beginning of the month.
Are there any special festivals or reasons to visit Hawaii in August?
There’s almost always a festival or celebration going on in Hawaii. The following list indicates the biggest festivals for August.
Hawaii, the Big Island
- Ho’oku’ikahi Establishment Day Hawaiian Cultural Festival
- 30 Days of Aloha on Hawaii Island
- Hawaiian International Billfish Tournament (Typically held in August, though sometimes held at the end of July)
Please note that festival dates are subject to change. For a comprehensive list of festivals and events, check out the search feature on Events tab under the Vacation Directory on the right sidebar of GoHawaii.com.
In summary, is August a good month to visit Hawaii?
Warm weather along with lower than average precipitation levels make August a pleasant time to visit Hawaii. The first half of August tends to be more expensive and crowded as compared to the second half, when rates are cheapest for August and below the annual average.
