Kauai is headed into a mostly clear and breezy night, then a sunny, breezy Saturday that should keep the island dry enough for most plans. For the rest of tonight, lows are expected to settle near 76 at the shore and around 67 above 3000 feet, with east winds of 10 to 20 mph.
That outlook is why the weather forecast today matters now: it gives a tight read on the hours people will actually be living through, not just a broad weekend summary. Saturday’s highs are forecast at 87 to 92 near the shore and around 78 above 3000 feet, with east winds holding near 10 to 20 mph, while Saturday night turns mostly clear again with lows of 70 to 81 near the shore and around 62 above 3000 feet.
The setup is improving after a relative decrease in shower activity through this weekend as a surface trough tied to the remnants of Norbert moves away. The forecast does not promise rain will vanish everywhere, but it does point to a quieter pattern, with decreasing shower coverage and limited activity focused more on windward and mauka areas than on a broader island-wide washout. That is a meaningful change after earlier instability and scattered thunderstorm activity in the area on Friday.
Trade winds are expected to stay moderate to locally breezy through Monday before easing gradually by midweek. The next sharper change is already on the horizon: another round of enhanced moisture is expected by next Tuesday, and that should bring shower activity back up statewide. For now, Kauai’s immediate story is simple — clearer skies, steady breezes and a brief window of calmer weather before the pattern turns wetter again.
