Redondo Beach, WA
CATEGORY 2
WHAT
Tides will reach approximately 19.7 ft in the evening hours (around 7:24 PM local time), with a moderate barometric pressure near 1005 hPa. NOAA’s flooding likelihood remains at 0%, indicating no risk of coastal flooding.
WHEN
Peak tide is expected around 7:24 PM local time on July 27.
IMPACTS
No shoreline flooding impacts are anticipated in low-lying areas. Roads and parks along the immediate waterfront should not experience inundation under these conditions.
• The highest tide for Day 1 (approx. 19.7 ft) is below the 21 ft level historically associated with more significant flooding.
• Barometric pressure (near 1005 hPa) is not especially low and does not closely match past flood events of higher categories.
• NOAA’s Flood Likelihood Analysis for July 27 remains at 0%, further supporting Category 2 (no flood risk).
CATEGORY 3
WHAT
An evening high tide near 19.6 ft combined with a lower barometric pressure (approximately 995 hPa) brings conditions close to a minor flood event. However, flooding would be unlikely to cause damage given the current forecast.
WHEN
Peak tide is expected around 7:54 PM local time on July 28.
IMPACTS
Little to no property damage is expected. Low-lying areas may experience occasional water pooling, but impacts appear minimal at this time.
• While the barometric pressure is lower than Day 1, the tide height remains under 20 ft.
• Historically, tides below 21 ft and pressures above ~992 hPa have tended to produce only minor or no flooding if wind conditions are not extreme.
• NOAA’s Flood Likelihood Analysis for July 28 is also at 0%, aligning with a lower chance of coastal flooding.
• Winds are forecast out of the north or northwest at modest speeds, not strongly favoring onshore water buildup.
CATEGORY 4
WHAT
A high tide near 19.3 ft will coincide with a notably low barometric pressure (about 992.25 hPa). This combination increases the potential for coastal flooding, although major property damage is not anticipated.
WHEN
Peak tide occurs around 8:18 PM local time on July 29, with the lowest barometric pressure forecast around the same period.
IMPACTS
Coastal roads, parking lots, and low-lying shoreline properties could see moderate flooding. Some areas may need minor protective measures (e.g., sandbags in immediate waterfront zones).
• Historical reference (e.g., January 7, 2022) shows that similar tide heights paired with barometric pressure in the 992–993 hPa range correlated with moderate flood events.
• Despite NOAA’s reported 0% likelihood, the notably low pressure at a relatively high tide height suggests close monitoring.
• Winds are forecast primarily out of the N/NNW. Even though this may reduce onshore push compared to southerly winds, the very low pressure remains a factor.
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.
