Mendip District Council is to offer free parking at its pay and display car parks until August 6.
The move means 40 council-run car parks across Wells, Frome, Glastonbury, Street and Shepton Mallet remain free to use for a further seven weeks.
Charges were suspended by the district council on March 26, to support communities and key workers during lockdown.
Mendip is also making stallholders at Wells and Frome markets a rent-free offer this summer in a bid to boost businesses and build back confidence in their shopping centres. All those operating in the market, which is managed by Mendip, will trade for free throughout June and July. The decision will then be reviewed on a month-by-month basis, for up to six months.
