Residents of Honolulu can expect mild weather conditions for the beginning of the week, though a cold front approaching the region may introduce some variability. As per the National Weather Service's Honolulu forecast, light east to southeast winds will continue as the front weakens and stalls north of the islands. The greater part of the moist and unstable weather conditions should remain off-shore, but Kauai could see increased shower activity if the front drifts southward than currently projected.
While light showers will predominantly grace windward slopes during the night and early morning, interior and leeward areas may experience a few afternoon showers due to sea breeze developments. The NWS forecast indicates that light easterly trades are likely to briefly return late tomorrow before veering back to an east-southeasterly flow on Tuesday, which could persist into midweek as another front begins to form well northwest of the islands. This front is expected to remain at a distance, sparing the state from significant weather disruptions.
In the aviation sector, these conditions mean continued light east-southeast winds with partial leeward area clearing overnight, and the possibility of interior cloud and shower development in the afternoon. "Brief periods of MVFR conds are possible in SHRA, otherwise VFR prevails," the forecast explained. An AIRMET Sierra warning is in effect for mountain obscuration on Kauai and could linger into the early morning period.
On the waters, the easing moderate to locally fresh east-southeast winds will stay suppressed into Monday due to the nearby front. The low-pressure development far northwest of the state is set to increase winds slightly, with them shifting out of the southeast come Tuesday. Surf along north and west facing shores is anticipated to near warning levels with a building northwest swell. A Small Craft Advisory was issued for exposed waters as seas could exceed 10 feet at the swell's peak. The swell should ease by midweek, leading to calmer conditions along east and south shores where the surf is already below seasonal averages, with only a small bump potentially arriving around midweek.
