5 Feet Storm Surge Flood Map for Boston Inner Harbor (TBHA)

If Blizzard Juno’s storm surge of 4.74 feet hit during high tide, it would have been a “100-year” flood event for Boston’s waterfront, reports Julie Wormser of The Boston Harbor Association. We were again very lucky as the surge hit during low-tide just after 11 a.m. on Tuesday. (See NOAA’s tide and current data.)

Despite the miss, the morning reading of 3.37 feet above high tide at 4:30 a.m. on January 27th was the third highest reading on Boston Harbor in the last five years.

Over the past three years, Boston’s waterfront has had five near misses of a “100-year” flood event, says TBHA.

  • Superstorm Sandy (October 29, 2012)
  • Blizzard Nemo (February 9, 2013),
  • Nor’easter Saturn (March 8, 2013)
  • Nor’easter Hercules (January 3, 2014)
  • Blizzard Juno (January 27, 2015)

The flood map shown above gives a sense of what areas are most at risk when a storm surge hits at high tide. For more information and ways to prepare, see BostonLivingWithWater.org.
