The Oak Bluffs fireworks will be canceled for a second straight summer due to the pandemic, the town firemen’s civic association announced Tuesday.

“Due to the uncertainty of the Covid-19 pandemic, we have no alternative other than to not schedule what would have been the 45th Oak Bluffs Firemen’s Civic Association Fireworks in August 2021,” association president James Moreis Jr. said in a post on Facebook.

Last summer would have marked the 45th year for the annual fireworks display that has long marked the grand finale of summer on Martha’s Vineyard. Thousands of Islanders and visitors of every stripe, from summer camp kids to visiting presidents, have attended the signature event held in the broad sweep of Ocean Park overlooking Nantucket Sound.

The event is a fundraiser for the firemen’s civic association, which raises money for scholarships and other community causes.

The announcement marks the first major summer cancellation as the pandemic enters a second year and uncertainty prevails amid concerns about protecting public health. On the Vineyard, as around the globe, vaccinations are in full swing, but case counts remain high and the emergence of virus variants pose new challenges, mandating continued strict safety protocols.
