Redondo Beach, WA
CATEGORY 1
WHAT
No risk of flooding is expected today. Normal tidal conditions will prevail.
WHEN
Throughout the day.
IMPACTS
No significant impacts are anticipated.
Assessment of Barometric Pressure:
The barometric pressure during the high tides on January 9th is approximately 1033 hPa at 02:06 AM and 1036 hPa at 09:42 PM. These pressures are significantly higher than those recorded during historical flooding events, such as the Category 5 event on 12/27/2022 with a pressure of 978.4 hPa. High barometric pressure indicates stable weather conditions, reducing the likelihood of severe weather-related flooding.
Evaluation of Tide Height:
The maximum predicted tide height for today is around 19.82 ft at 12:06 PM. This is lower than the tide heights observed during historical Category 3 events (e.g., 20.68 ft on 01/06/2025) and significantly lower than Category 4 and 5 events exceeding 21 ft. The tide height alone does not indicate a flood risk under these conditions.
Wind Direction and Speed:
Wind speeds are low, ranging from 2 to 6 mph, with wind directions primarily from the East-Northeast (ENE) to South-Southeast (SSE). These wind conditions are not known to contribute significantly to flooding in the area, unlike winds from the West/Northwest which can exacerbate tidal effects.
NOAA High Tide Flooding Likelihood:
NOAA's forecast indicates a low flood likelihood for January 9th, with a likelihood percent of 0.7% and a distance to the flood threshold of -1.19 meters. This suggests that tides are well below levels that typically cause flooding in the region.
Comparison with Historical Events:
Compared to historical Category 3 and higher events, today's high barometric pressure and moderate tide heights indicate a significantly lower risk of flooding. The lack of severe weather conditions further supports a Category 1 classification.
CATEGORY 1
WHAT
No risk of flooding is expected today. Tidal conditions are within normal ranges.
WHEN
Throughout the day.
IMPACTS
No significant impacts are anticipated.
Assessment of Barometric Pressure:
The barometric pressure remains high on January 10th, measured at approximately 1034.6 hPa during the high tide at 12:36 PM and 1035.4 hPa at 03:24 AM. These values are well above the low-pressure thresholds associated with increased flood risk in historical events.
Evaluation of Tide Height:
The maximum predicted tide height is approximately 18.83 ft around midday. This is below the tide heights linked to past flooding incidents, such as the 22.297 ft observed during the Category 5 event on 12/27/2022.
Wind Direction and Speed:
Wind speeds are modest, ranging from 4 to 12 mph, with directions from South-Southeast (SSE) to Northeast (NE). These wind conditions do not align with those that have historically contributed to flooding in Redondo Beach.
NOAA High Tide Flooding Likelihood:
NOAA reports a low flood likelihood for January 10th, with a likelihood percent of 0.1% and a distance to the flood threshold of -1.55 meters. This indicates minimal risk based on tidal predictions and thresholds.
Comparison with Historical Events:
The combination of high barometric pressure, moderate tide heights, and low wind speeds contrasts with conditions during historical flooding events. Therefore, the flood risk remains low and is classified as Category 1.

WHAT
No flooding is expected today. Normal tidal conditions will prevail.
WHEN
Throughout the day.
IMPACTS
No significant impacts are anticipated.
Assessment of Barometric Pressure:
On January 11th, the barometric pressure is approximately 1030.5 hPa during the high tide at 04:24 AM and 1028.85 hPa at 01:30 PM. While slightly lower than the previous days, these pressures are still significantly higher than those associated with historical flooding events, indicating stable atmospheric conditions.
Evaluation of Tide Height:
The maximum predicted tide height is around 19.64 ft early in the morning. Although this is a relatively high tide, it remains below the heights seen in past flood events categorized as Category 3 or higher.
Wind Direction and Speed:
Wind speeds are low to moderate, between 3 to 7 mph, primarily from the South-Southeast (SSE) to South (S). These wind directions are not expected to contribute to any flood risk.
NOAA High Tide Flooding Likelihood:
NOAA forecasts a low flood likelihood for January 11th, with a likelihood percent of 0.1% and a distance to the flood threshold of -1.56 meters. This suggests that tidal conditions pose little to no flood threat.
Comparison with Historical Events:
The absence of low barometric pressure combined with moderate tide heights and benign wind conditions indicates that the risk of flooding is minimal. Conditions are not comparable to any historical events that resulted in flooding, supporting a Category 1 classification.
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.
