Honolulu residents and visitors can expect a shift in winds and intermittent showers over the next several days. According to a recent NWS Honolulu Weather Forecast, trade winds are set to briefly ease later today through tomorrow before ramping back up to breezy conditions from Friday into the weekend. Rainfall will generally target windward and mauka areas.
The forecast on NWS indicates a dry trade wind pattern for today, with "a mostly dry trade wind pattern prevailing" as surface high pressure stays put to the north. Shower coverage could increase notably, especially in windward and mauka locales, as a broad surface trough is expected to weaken the local trades. The NWS cautions that the trough, along with a mid-level trough and a surge in low-level moisture, may possibly lead to more showers from tonight through tomorrow night.
Aviation reports suggest that moderate to locally breezy trade winds will help keep most shower activity confined to windward areas this morning. VFR conditions are anticipated elsewhere with a notable decline in shower activity by late morning, before a resurgence tonight. The marine outlook carries a similar theme with moderate to strong trade winds persisting through the weekend. A Small Craft Advisory is in effect until 6 PM HST this evening due to these conditions.
Surf conditions across the state are also under watch. While north facing shores are slated for minimal activity, the south swell is expected to peak above average on Monday, subsequently declining through mid-next week. Coastal areas should brace to potentially see minor flooding mid-August, coinciding with the full moon and higher than average water levels. The forecast suggests that a Coastal Flood Statement is forthcoming as the situation develops.
For those trying to make plans around the weather, it's important to monitor local advisories and forecasts closely. The Small Craft Advisory will affect several areas including Maalaea Bay and Big Island leeward waters. With conditions changing into and throughout the weekend, not only mariners but all residents should stay informed.
