Redondo Beach, WA
CATEGORY 3
WHAT
High tides peaking around 20.76 ft are expected with a relatively high barometric pressure near 1023.5 hPa. These conditions are close to a flood event and worth monitoring, but widespread or significant property damage is not anticipated.
WHEN
Highest concern around the early morning hours (approximately 03:00 AM to 08:30 AM PST) when tides reach their peak.
IMPACTS
• Minor flooding in low-lying areas along the immediate shoreline.
• Brief ponding on coastal roads or park areas may occur.
• No major property damage is expected at this time.
Barometric pressure is higher than typical severe flood events, reducing the chance of more serious impacts despite the elevated tide level. NOAA’s Flood Likelihood for 2025-12-08 is indicated as 20.0%, but historical Category 3 comparisons (e.g., 01/06/2025) had similar tide heights and did not result in extensive damage. Winds remain moderate and do not suggest worsened flooding potential.
CATEGORY 3
WHAT
Tides reaching about 20.55 ft combined with notably high barometric pressures of 1025+ hPa. Conditions are again close to a flood event, warranting attention, but still unlikely to produce significant property damage.
WHEN
Highest risk window around mid-morning (approximately 08:30 AM to 09:30 AM PST) when the tide peaks.
IMPACTS
• Potential minor inundation along the shoreline.
• Occasional standing water on roads nearest the beach.
• Widespread property damage is not expected.
Although NOAA projects a 12.1% flood likelihood for 2025-12-09, the tide remains under 21 ft. Historical data shows that when tides are below 21 ft and paired with high barometric pressure, actual flooding impacts tend to be minor, aligning with a Category 3 designation.
CATEGORY 2
WHAT
Projected tide heights near 20.32 ft, with very high barometric pressure around 1027.75 hPa, well above the low-pressure thresholds typically associated with notable flooding.
WHEN
Morning high tide (approximately 09:00 AM to 10:00 AM PST) creates the primary focus window, but overall flooding risk remains minimal.
IMPACTS
• No significant flooding concerns are indicated; overall risk is very low.
• Little to no impact on property or coastal infrastructure.
Despite NOAA labeling a “High” likelihood category for 2025-12-10, the actual percentage (5.3%) is relatively low, and the tide remains below 21 ft. Extremely high barometric pressure further reduces the potential for any coastal flooding, placing conditions firmly at Category 2 (no risk of flooding).
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.
• Categories 1-2: No risk of flooding.
• Category 3: Close to a flood event and worth monitoring.
• Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
• Category 5: Likely to flood and cause property damage.
• Categories 6-7: Extremely high risk of flooding and property damage.
