The supermoon on November 14 caused high-rising tides the next morning. The above picture, taken at 8:30 a.m. on November 15, shows the tides rose to levels that matched construction work on the Padanaram Causeway.

"Luckily it was calm. Any southerly wind or waves, and lots of dirt would have been washed into the harbor," said Harbormaster Steve Melo.

It is not yet clear if the high tides causes any damage or delay to the causeway project.
