Flood Watch

Redondo Beach, WA

Day 1: 2026-04-21

CATEGORY 3

WHAT Category 3 conditions are expected, primarily due to a moderately high tide and slightly lower-than-usual pressure. Residents should keep an eye on the water level along the immediate shoreline, especially during high-tide periods.

WHEN Peak water levels are likely in the early morning around 7:24 AM and again overnight near 10:12 PM.

IMPACTS • Minor inundation possible at immediate shoreline.

REASONING The moderately high astronomical tide is the main driver, with modest support from pressure slightly below standard levels. Onshore wind is minimal and not a significant contributor. This is similar to a past Cat 3 event on 2023-01-06.

Day 2: 2026-04-22

CATEGORY 2

WHAT No flooding risk is expected. Tides are near normal, and pressure is not low enough to raise concerns.

WHEN High tides will occur in the morning around 8:18 AM and late at night near 11:24 PM.

IMPACTS • No impact anticipated.

REASONING Routine tide levels are the main factor, with a slight effect from pressure. Wind contributions remain minimal. One closest analog day was a Cat 3, which is higher than this forecast’s Cat 2.

Day 3: 2026-04-23

CATEGORY 1

WHAT No flood risk. Tides are relatively modest, and pressure is comfortably above low thresholds.

WHEN The highest tide arrives in the mid-morning near 9:24 AM.

IMPACTS • No impact anticipated.

REASONING Overall tide levels are fairly low, and pressure is near normal, keeping conditions well below thresholds for concerns. This aligns with a similar Cat 1 day on 2024-03-02.
