The heat wave that blanketed much of the country with soaring temperatures and sticky humidity all weekend did not spare Martha’s Vineyard, where hundreds of vacationers and working Islanders flocked to cooling shoreside places on Saturday and Sunday. Town libraries and public safety buildings were opened for people needing relief from the heat.

The National Weather Service station in Edgartown recorded a high of 92 on Saturday.

On the water was a good choice too.

On Sunday, the NOAA weather website recorded a high of 92 at the Martha’s Vineyard Airport.

Spot checks with Island police and fire departments turned up no major heat-related problems. The West Tisbury and Vineyard Haven libraries were both opened on Sunday as cooling centers. People were advised to take proper precautions by staying hydrated and checking in on their neighbors.

In West Tisbury, police Sgt. Garrison Vieira said his department had responded to one incident that may have been heat related.

Edgartown fire chief Alex Schaeffer said Island emergency managers would pool resources if they saw more people than one community could handle on its own.

It was too hot for outdoor Shaksepseare — the Vineyard Playhouse canceled its performance of The Winter’s Tale Saturday night at the Tisbury Amphitheatre.

But most events went on as planned, including the Feast of the Holy Ghost in Oak Bluffs on Saturday night and Sunday morning, the public safety day in Aquinnah on Saturday and the gala fundraiser at Featherstone Center for the Arts Saturday night.

The extreme heat was expected to break on Monday, with rain and cooler temperatures in the forecast.
