The Massachusetts Coast will see its highest tides in 2016 in mid-October, when the sun and the moon are aligned and the earth orbits closest to the sun. This year, Boston Harbor's highest annual tides will occur:

Monday, October 17, 12:31 pm

Tuesday, October 18, 1:21 pm

Wednesday, October 19, 2:13 pm

Check here for high tide times across other sections of the Massachusetts coastline

Known as a "King Tide" (or locally, a "WICKED wicked high tide"), these three high tides will be over two feet higher than average and give us a glimpse of our average high tide sometime around or after mid-century.

Boston Harbor Now, Mass Bays National Estuary Program, the New England Aquarium, UMass Sustainable Solutions Lab and the Museum of Science are joining forces to crowdsource photos documenting portions of the Massachusetts coastline expected to flood during the King Tide. See below for our predictions of where you might see tidal flooding.

If you are in one of these areas within 20 minutes of the King Tide, could you take a picture of high tide and take notes of when and where you took it? Once you're ready to send us your photos, here are two great ways to do so:

Go to MyCoast on your computer or download the MyCoast app on your tablet or smartphone and create an account to upload your photos. When you use the phone app to upload photos, the time, location and tidal phase will be automatically stamped on your photo. If you don't want to do this for whatever reason, you can email your photos to Boston Harbor Now, care of Julie Wormser: jwormser@bostonharbornow.org and we will upload your photos for you. Please make sure to tell us the location, date and time and how to credit each photo.

Thanks everyone!
