Redondo Beach, WA
CATEGORY 3
WHAT
Close to a flood event and worth monitoring. The tide is forecast to peak near 19.8 ft, and while this is notable, widespread or damaging flooding is unlikely under current conditions.
WHEN
Highest tide generally around early morning (02:06 AM) and late afternoon (around 05:30 PM).
IMPACTS
• Minor ponding of water possible in the lowest-lying areas.
• Very limited potential for property impacts or road closures at this time.
Barometric pressure around high tide is expected to be roughly 1002–1005 hPa, which is not extremely low but does warrant some attention. Historically, Category 3 events in Redondo Beach have seen comparable tide heights around or just under 20 ft alongside moderate pressures. No significant wind speeds are forecast. Overall, conditions suggest close monitoring but a low likelihood of flood damage.
CATEGORY 4
WHAT
Flooding is likely, though major property damage is not expected. The forecast high tide is over 20 ft, raising concern for minor to moderate coastal flooding.
WHEN
Peak tide near 06:12 PM, with the tide expected to reach about 20.1 ft.
IMPACTS
• Possible flooding of beaches, parking lots, and some low-lying roads.
• Potential for minor property impacts along the immediate shoreline.
Barometric pressure near this high tide is projected around 1008.5 hPa. Although not very low, it’s lower than pressures associated with some previous moderate tide events, which slightly increases the chance of minor flooding. Historical Category 4 events have included tide heights in the 19–21 ft range, often with similar or lower barometric pressures. Winds are not expected to be particularly strong, but vigilance is advised.
CATEGORY 4
WHAT
Another day of likely minor to moderate flooding, with tide heights again climbing above 20 ft. Flooding is probable but major property damage is unlikely.
WHEN
Highest tide late afternoon to early evening (about 06:54–07:00 PM), reaching around 20.2+ ft.
IMPACTS
• Temporary flooding of low-lying roads and shoreline infrastructure possible.
• Minor property impacts may occur in areas that are historically more flood-prone.
Though precise barometric pressure near the peak tide is not given, forecasts suggest around 1004–1006 hPa, which is moderately low. This combination of moderately low pressure and a tide exceeding 20 ft aligns with historical Category 4 floods that have caused noticeable—but generally not severe—coastal inundation. Expect mostly minor flooding impacts near shorelines and waterfront roads without major wind complications.
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.
