Redondo Beach, WA
CATEGORY 2
WHAT
High tide levels near 19.2 ft are expected in the afternoon (around 16:24), but the barometric pressure remains elevated near 1021 hPa. With calm wind conditions and NOAA’s stated 0% flood likelihood, no flooding is expected.
WHEN
Peak high tide around mid to late afternoon on 2025-09-20 (roughly 15:30–17:00).
IMPACTS
No significant impacts anticipated. Minor water movement around low-lying spots along the shoreline, but no property damage or road closures are expected.
Historical comparisons show Category 3 or higher flood events typically involve lower barometric pressure (often below 1006 hPa) along with tides over 20 ft. Here, the tide is below 20 ft, winds are relatively mild, and pressure is relatively high. NOAA also indicates no flood threat, supporting a Category 2 (no risk) forecast for the day.
CATEGORY 2
WHAT
High tide again reaches near 19.1 ft around 16:42, with a barometric pressure of approximately 1020 hPa. Wind speeds remain moderate, and NOAA continues to indicate 0% flood likelihood.
WHEN
Peak high tide anticipated mid-to-late afternoon (roughly 15:30–17:00).
IMPACTS
No flooding is expected. Water levels may be noticeable near shorelines, but no inundation of roads or significant property impacts are anticipated.
Comparisons to events with flood impacts reveal that stronger onshore winds, significantly lower atmospheric pressure, and higher tide heights are the key drivers of coastal flooding in this region. None of these factors meet the thresholds observed in past Category 3 or above events.
CATEGORY 2
WHAT
A daytime high tide close to 18.95 ft is forecast near 17:00, with barometric pressure around 1015 hPa. Though the pressure is slightly lower than the previous two days, it remains well above typical flooding thresholds, and NOAA data maintains a 0% likelihood of flooding.
WHEN
Primary high tide window in the late afternoon to early evening (approximately 16:30–17:30).
IMPACTS
No flood impacts are expected. Minor wave action along low-lying coastline areas, but the overall risk remains low.
Examining past severe events (Category 4 or 5) highlights substantially higher tides (often above 20 ft) combined with notably lower barometric pressure, sometimes below 995 hPa. Today’s estimates do not align with those conditions, keeping the flood category at Level 2.
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.
