This histogram provides the maximum water levels of the 38 recorded storm tide events at South Padre Island since 1900. The events are ordered from the highest water level (Rank = 1) to lowest (Rank = 38). These events are not placed in chronological order. All data are detrended to remove the influence of relative sea level rise, so they represent water levels above an Annually-Adjusted Mean Sea Level (AAMSL).
Time series provides of maximum water levels from 38 recorded storm tide events at South Padre Island since 1900. These events are ordered chronologically from oldest (left) to newest (right). The numerous low-magnitude events in recent decades are influenced by both climate and data availability. All data are converted to NAVD88 datum, however, the data are intentionally not detrended, so the influence of relative sea level rise is included. SLR trend taken from NOAA tide gauge at Port Isabel.
Statistics/ Return Period
The U-Surge Project has calculated extreme water levels for South Padre Island, including the heights of the 500, 200, 100, 50, 25 and 10-year storm surge levels. These data-driven water levels are typically higher than FEMA's model-driven data, with the 100-year water level ranging from 2-4 ft higher than FEMA's 100-year level for most cities. Extreme water level analysis is available upon request. Email: [email protected].
Sea Level Rise and Future Extreme Water Levels
The U-Surge Project has documented historic sea level rise and various sea level rise projections for South Padre Island. Sea Level Rise projections are added to extreme water levels (section above) to enable users to estimate future extremes in a changing climate. Sea level rise and future extreme water levels are available upon request. Email: [email protected].

Missing Data
We have identified eight hurricanes/ tropical storms that may have generated storm surges exceeding 4 ft (1.22 m) near South Padre Island/ Port Isabel between 1900- present, but a literature review does not yet provide data. The maps are provided by Unisys Corporation.

Hurricane Isaac (2012) produced substantial waves but minimal storm surge at South Padre Island. We posted this video because: 1) It shows the power of hurricanes to displace water across great distances; 2) People were surfing/ having fun in a responsible way...on waves outside the main impact zone (we do not post videos of people in waves near the impact zone); and 3) Many of us involved in this research have coastal interests and love to surf!
This video provides some nice storm surge footage. Easy to see in beginning, but look closely through storm door in middle of video and you can see waves hitting the building where video was taken. Click video for source.
