Flood Watch

Redondo Beach, WA

Day 1: 2026-09-18

CATEGORY 1

WHAT A routine day with no flood risk. The modest tide and near-normal pressure keep water levels well below flood thresholds.

WHEN Highest tides around 12:30 PM and again near 10:06 PM.

IMPACTS • No impact anticipated.

REASONING Tide was the primary factor, although it remained moderate. Pressure was near normal, and onshore wind contributions were minimal. This is similar to the 2024-06-14 Cat 1 event.

Day 2: 2026-09-19

CATEGORY 1

WHAT Continued routine conditions with no expected flooding. Tide heights remain relatively normal, and light winds do not pose any flooding threat.

WHEN Peak tides near 1:54 PM and 11:30 PM.

IMPACTS • No impact anticipated.

REASONING Tide remained the main driver, while pressure stayed near normal and wind contribution stayed minimal. This is similar to the 2026-05-07 Cat 1 event.

Day 3: 2026-09-20

CATEGORY 1

WHAT No flood concerns as conditions stay benign. Slightly lower-than-average pressure is not enough to cause flooding, and onshore wind is almost negligible.

WHEN Peak tide in the mid-afternoon, around 2:54–3:00 PM.

IMPACTS • No impact anticipated.

REASONING Higher tide played the biggest role in the forecast, with slightly below normal pressure also contributing, but neither is sufficient to produce a flood. Wind effects remain minimal. This is similar to the 2026-08-09 Cat 1 event.
