Redondo Beach, WA
CATEGORY 2
WHAT
No coastal flooding is anticipated. Tide heights will reach approximately 17.8 ft during the evening high tide, which is below levels associated with past close-call (Category 3) flood events. Barometric pressure around 1012.6 hPa is relatively high compared to historical flood cases, reducing the likelihood of any significant flooding.
WHEN
Highest tide occurs near 8:00 PM to 9:00 PM local time.
IMPACTS
No notable flooding impacts expected. Low-lying waterfront areas should remain unaffected.
• NOAA Flood Likelihood percent is listed as 0.0% for 2025-08-29.
• Winds remain light, and the barometric pressure remains well above the historically significant low-pressure thresholds (<992 hPa).
• Compared to the 12/27/2023 Category 3 event (17.46 ft tide with lower pressure at 1006.1 hPa), today’s higher barometric pressure helps keep flood risks minimal.
CATEGORY 2
WHAT
Again, no flooding is expected. The peak tide is near 17.3 ft with a barometric pressure near 1009.9 hPa, still higher than pressures historically linked to flood concerns.
WHEN
Highest risk period around the late evening hours (8:00 PM–9:00 PM).
IMPACTS
No immediate impacts to coastal infrastructure are anticipated. Any minor water encroachment is unlikely to affect roadways or properties.
• NOAA Flood Likelihood is 0.0%.
• Although pressure is slightly lower than on Day 1, it remains above critical thresholds seen during historical flooding.
• Tidal heights remain below 20 ft, further reducing chances of significant inundation.
CATEGORY 2
WHAT
No significant coastal flooding is expected. The maximum tide height (about 16.95 ft) and a barometric pressure around 1004.8 hPa remain within safe ranges compared to historical flood events.
WHEN
Peak tide occurs midday (~12:30 PM) with secondary lower peaks overnight.
IMPACTS
Little to no flooding anticipated. Waterfront areas and infrastructure are expected to remain unaffected.
• NOAA projects a 0.0% flood likelihood for this date.
• Although today’s barometric pressure is somewhat lower than Days 1 and 2, it does not approach the historically low pressures associated with damaging floods.
• Historical Category 3 events typically recorded higher tides (17+ ft) at significantly lower pressures (~1006 hPa or less), which is not the case here.
You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
