Redondo Beach, WA
CATEGORY 2
WHAT
No flooding is expected. Although tide levels will reach around the mid-17 ft range, barometric pressure readings are not low enough to indicate a significant coastal flood threat.
WHEN
Peak tide around late morning (approximately 10:00 AM).
IMPACTS
No anticipated flood-related impacts. Normal beach and shoreline activity should be unaffected, and roads near the coast are expected to remain clear.
• Barometric pressure is relatively high (above 1013 hPa at peak tide), reducing the possibility of storm surge.
• NOAA’s flood likelihood for 2025-09-28 is 0.0%, which further supports minimal flood risk.
• Historically, higher-category coastal events in this region have required notably lower barometric pressures (near or below 992 hPa) paired with tides above 20 ft.
CATEGORY 2
WHAT
No flooding is expected. Tide heights remain in the same general range as Day 1, and although the barometric pressure dips slightly (near 1007 hPa), it stays well above the historical low-pressure thresholds associated with flood events.
WHEN
Peak tide early to mid-morning (approximately 04:54 AM as one of the higher tides).
IMPACTS
No widespread issues anticipated. Low-lying areas along the shore should remain unaffected based on current forecasts.
• Barometric pressure at peak tide is around 1007 hPa, which is still significantly higher than the 992–1002 hPa range customarily linked with more substantial flooding.
• NOAA’s flood likelihood for 2025-09-29 is also 0.0%, indicating very low risk.
• Historic Category 3 or 4 events in Redondo Beach typically had higher tide levels (exceeding 20 ft) and/or lower barometric pressures.
CATEGORY 2
WHAT
No flooding is expected. Tides will be slightly higher than on previous days, potentially nearing the upper 17 ft range. However, the barometric pressure (near 1004 hPa at one high tide) remains well above the critical low-pressure benchmarks seen in notable flood events.
WHEN
Midday into early afternoon holds the highest tide (peak near 12:30–12:45 PM), but overall conditions do not suggest a flood threat.
IMPACTS
No immediate or significant concern for coastal flooding. Usual beach and nearshore activities should remain unaffected.
• While the tide height is marginally greater than Days 1 and 2, the barometric pressure is not low enough—based on historical comparisons—to raise concerns.
• NOAA’s flood likelihood for 2025-09-30 remains 0.0%.
• Past Category 3 events in this area have typically involved confirmed flooding reports and stronger onshore winds with much lower air pressure.
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.
