The Hawaiian Islands are generally thought to experience near-perfect weather year-round — at least to those who don’t live here. For locals, however, we understand the nuances of Hawaii’s changing weather, and how drastically different the wet season can be from the dry season, and even from year to year. A few weeks ago, the National Oceanic And Atmospheric Administration issued a wet season rainfall outlook for the state of Hawaii for October 2017 through April 2018 — and depending on where you live and whether you love or hate rain, this could be either good or bad news. Let’s take a look:
Based on NOAA’s research, the Hawaiian Islands are set to experience above average rainfall through the traditional "wet season" — at least on the islands’ windward coasts, which have been experiencing a drought. On the islands’ leeward coasts, however, the existing drought may persist or worsen. This is especially true for Maui and Hawaii Island.
On average, the Hawaiian Islands receive just under 18 inches of rainfall annually, and experience 154 days of rainfall each year.
Predictions and averages, of course, are based on large-scale conditions and do not take into consideration the myriad of microclimates that exist throughout the state. After all, 10 of the world’s 14 climate zones can be found on Hawaii Island alone.
NOAA’s Climate Prediction Center has reported that the current ENSO-neutral conditions — which indicates that neither El Nino and La Nina are present — are likely transitioning to a La Nina state (cool phase). The CPC issued a "La Nina Watch" for Hawaii in September, and there is a 55 to 60 percent chance of La Nina developing this fall. This forecast is thought to persist until the spring when conditions may transition back to ENSO-Neutral.All this scientific talk too complicated for you? Same here. Bottom line: prepare for more rain than normal if you live on the islands’ windward coasts. If not, well… who knows what the leeward coasts will experience this year in terms of rainfall. We can only hope that the drought lessens.
My advice: make sure you have an umbrella in your car and a raincoat in your hiking pack. As we all know, the rain can start and stop quite suddenly in Hawaii. If, however, it has been consistently raining for quite some time, I’d stay off the remote trails. Streams have been known to flood quickly and dangerously.
At least with all this predicted rain comes one of our favorite things: rainbows!
It looks like we might get to see more of these 9 Hawaiian waterfalls that only come out when it’s raining this year. Oh, and here are 13 things to do when it’s raining in Hawaii.
