Nearly four dozen beaches remained unsafe for swimming on Tuesday as Massachusetts prepared for its latest extreme heat stretch that will send "feels-like" temperatures past 100 degrees this week.
The National Weather Service issued a Heat Advisory starting at 11 a.m. on Tuesday and lasting until 8 p.m. on Wednesday for most of the Bay State.
"Hot temperatures and high humidity may cause heat illness," the NWS said. "Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors."
The Heat Index on Tuesday and Wednesday is forecast at 103 degrees.
The NWS also issued an Elevated Fire Risk for much of the state on Tuesday.
"Hot temperatures combined with gusty southwesterly winds 20 to 35 mph are expected across Massachusetts," the NWS said. "These conditions, combined with a lack of recent rainfall, fuel conditions, and recent fire activity, will lead to elevated fire weather concerns. Use caution when handling and disposing of ignition sources such as matches and cigarettes."
Tuesday's forecast is sunny and hot with a high temperature of 96 degrees. While dewpoints will be in the high 60s, there could be some relief in the persistent southwest breeze.
It will stay very warm Tuesday night with a low temperature of only 80 degrees and "no nighttime relief" for those without AC.
Wednesday will be another scorcher with a high temperature of 95 degrees and feels-like temperatures over 100 degrees.
Thursday will also be near 90 but with much less humidity.
The heat returns as 43 Massachusetts beaches remain closed to swimming after tests showed bacteria exeedence in the water.
The bacteria used as indicator organisms to test the waters at beaches are Enterococci and E. coli. Marine beaches are tested for the presence of Enterococci. Freshwater beaches are tested either for the presence of E. coli or Enterococci. Enteric bacteria are indicator organisms found in the intestines of warm-blooded animals and humans, often associated with fecal contamination.
An elevated presence of these organisms indicates the water may not be safe for human or animal consumption or contact, and may cause symptoms ranging from gastrointestinal pain to eye and ear discomfort to flu-like symptoms.
Most of these symptoms are minor, but occasionally a more serious illness may occur. Children, the elderly, and those with weakened immune systems are at greater risk of developing serious symptoms.
Some beach areas may remain open for recreational activities, though any contact with the water is strongly discouraged.
Massachusetts beaches closed as of 10 a.m. on Tuesday included:
