Flood Watch

Redondo Beach, WA

Day 1: 2026-09-01

CATEGORY 2

WHAT A routine day with no significant flooding risk. Slightly below normal pressure and moderate high tide levels are present, but onshore wind is minimal.

WHEN Peak high tides are expected in the morning around 8:30 AM and again in the evening near 8:12 PM.

IMPACTS • No impact anticipated.

REASONING The moderate astronomical tide is the primary factor, while the slightly below normal pressure adds a small contribution. Onshore wind does not significantly affect conditions. One close analog day, 2026-01-05, reached Category 3, but overall conditions today remain lower at Category 2.

Day 2: 2026-09-02

CATEGORY 3

WHAT Close to flood conditions due to a moderate high tide combined with noticeably below normal pressure. Although onshore wind is present, it is not the main factor.

WHEN Highest water levels will occur in the morning near 9:36 AM and in the evening around 8:48 PM.

IMPACTS • Minor inundation possible at immediate shoreline.

REASONING The moderate tide is the main driver, with additional support from below-normal pressure. Onshore wind remains modest. Ensemble guidance fully agrees on Category 3 with no higher-tail scenario. One close analog is 2026-01-07, also a Category 3 event.

Day 3: 2026-09-03

CATEGORY 2

WHEN Peak high tides in the late morning around 10:54 AM and evening near 9:30 PM.

IMPACTS • No impact anticipated.

REASONING Elevated tide is the main factor, with moderate support from slightly below normal pressure. Onshore wind is light. All ensemble models agree on Category 2 without higher tail risk.
