Monday is starting out mostly clear and plenty muggy in Honolulu, with Daniel K. Inouye International Airport near 72°F and an east-northeast breeze around 9 mph. Highs will climb into the low-to-mid 80s, with mostly sunny afternoons after a few isolated morning showers. Windward and mauka neighborhoods should keep something handy for quick early-morning downpours.
What To Expect Today
Isolated showers may pop up before noon, followed by mostly sunny skies and a high near 84°F. East-northeast winds will run about 9 to 17 mph, with gusts reaching into the mid-20s in more exposed spots. Overnight, temperatures will settle back into the low 70s.
Midweek Outlook
An upper-level trough is expected to deepen into a weak low near Kauai by Tuesday, which will lift cloud tops and boost the number of overnight and early-morning showers through midweek. Trade winds are forecast to strengthen on Wednesday and Thursday, with east-northeast winds in the mid-teens and gusts possibly topping out in the upper-20s to near 30 mph, which could lead to Small Craft Advisory conditions on the windier waters. According to the National Weather Service, new showers will favor windward mountain slopes and the nighttime and early-morning hours.
Boating, Surf And Commute Notes
Boaters should check harbor advisories before heading out, with choppier channels expected later in the week and a modest bump in north- and west-facing surf by the weekend. For drivers and cyclists, brief early-morning showers on windward and mauka routes could cut visibility for a short time, so plan a little extra travel time and secure lightweight outdoor items if you live in more exposed, gusty areas.
