For those in Honolulu, the weather dance continues much as it has, with the National Weather Service predicting a familiar rhythm of trade wind conditions and the occasional rain shower, primarily affecting windward and mauka areas. The current weather pattern, according to a bulletin from the NWS Honolulu, is driven by "high pressure far the northeast" that's ushering in those breezy trade winds we're all used to, with an added note that a weak upper low may bring in a bit more rain through the end of the week.

The city's weather watchers can look to hold steady on the preparations and expectations, making sure the gutters are clear and perhaps reconsidering that car wash, as those trades are anticipated to hang somewhat tough until mid-week. They might ease up just enough to effortlessly catch a breath before hitting us anew over the weekend, when another disturbance may kick up the showers a notch.

In the aviation sector, anyone with their eyes skyward or set to take flight will be noting periods of windward and mountain showers, which could lead to brief MVFR conditions, notably "favoring the overnight to early morning hours," according to the NWS alert. And for those at sea, mariners should be wary as a Small Craft Advisory (SCA) is hoisted for most Hawaiian waters. The winds may relent a touch by tonight, but the SCA is expected to remain for the typically windier spots near Maui and the Big Island into mid to late week.

Surfers catching this forecast will be angling to take advantage of today's moderate period south-southwest swell delivering the goods to south facing shores. This swell is slated to slowly dip as the week progresses, so make sure to get out there and quickly snatch some waves before they become mere whispers by weekend. Meanwhile, east-facing shores will continue to offer rough and choppy conditions, with trade winds ensuring that "surf along east-facing shores will be rough and choppy" for the majority of the week, even as they begin to slightly decline tonight through mid-week, per NWS predictions.

As for advisories, two Small Craft Advisories are in place as of now. One until 6 PM HST this evening covers areas including Kauai Northwest Waters, Kauai Leeward Waters, amongst others, and the second advisory extends until Tuesday evening for waters around Maalaea Bay and the channels near the Big Island. A full list of the advisories and affected regions can be referenced at the NWS Honolulu site.
