Saturday morning's temperatures dipped to 29 degrees, not cold enough for the Boards of Health to consider lifting the evening organized activity ban in both.
"It never reached 28," Town Manager Michael Lombardo said on Saturday.
It needed to drop to 28 degrees or lower for four hours or longer for a hard freeze, he said. A hard freeze was needed to lift the ban.
Earlier this month, the Boards of Health in both towns put in place an organized activity ban from 5 p.m. through 8 a.m. because of the threat of Eastern equine encephalitis.
On Thursday, WHDH-TV meteorologist Pete Bouchard told Hamilton-Wenham Patch that there was a good chance of a hard freeze on Saturday morning.
But Lombardo said National Weather Service records indicate that the temperature got to 29 degrees on Saturday morning.
Bouchard this week there is no chance of temperatures getting to even freezing, let alone a hard freeze, for the upcoming week.
