Kekaha, HI Coastal Erosion Rate
Shoreline change 7.3 miles northwest of Kekaha, HI
Nothing alarming measured 7.3 miles northwest of Kekaha, HI: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
The grain of this number
Kekaha, HI is the nearest named place, 7.3 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 22.05, -159.78. Survey years: 2007-2010, method WLR, from USGS's Hawaii shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
Where this fits nationally
Averaging 106 separate transects produced this segment's rate, with 82% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.49 ft/yr either side. The unadjusted figure here, -0.1 ft/yr, would place it 646 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2011-1009. Ocean City, NJ sits at national rank 1162 for growth (2.2 ft/yr), one reference point among the 1211 scored segments, 5021 miles from here. 1.4 miles up the coast, Kekaha, HI shows the same lack of a significant trend.
