The summer’s last Alive Bay the Bay festival happens in downtown Bay Shore on Wednesday, Aug. 23.

This summer marked the first for the Alive by the Bay series, which is inspired by Patchogue’s Alive After Five. The events are organized by the Chamber of Commerce of Greater Bay Shore’s restaurant committee.

Here are things to know before you go:

• The National Weather Service forecast for Wednesday in Bay Shore: A 40 percent chance of showers and thunderstorms before 1 p.m. Cloudy, then gradually becoming mostly sunny, with a high near 84. (As of Sunday night.)

• The first two Alive by the Bay festivals drew huge crowds to the downtown. The organizers are strongly encouraging the use of mass transit, with the LIRR station being just a couple blocks north of Main Street. (Or get there early!)

• Alive by the Bay runs from 6 p.m. to 10 p.m., with road closures beginning at 5 p.m. Main Street is closed from Bay Shore Avenue/Shore Lane west to Ocean Avenue. Cars will have to be off Main Street starting at 3 p.m.

• Maple Avenue will remain open for vehicles to access the Fire Island ferries to the south. No side roads are closed. Police, crossing guards and security officers will be on hand to assist pedestrians across Maple while keeping vehicle traffic flowing.

•  The bands set up at two main stages. One is near the Boulton Center at 37 West Main Street. The other is near where Third Avenue meets East Main Street.

• The live music starts at 6 p.m.  Atomic Red Hots will be performing on the Third Avenue stage, with 1 Step Ahead outside the Boulton Center. Whiskey Road will be performing at the Bay Shore Bandshell just west of the Boulton Center on the south side of Main Street.

• The serving of any alcoholic beverages outdoors will stop at 8:55 p.m. [Editor’s note: The time for last call has been corrected from prior reports.]

• The town’s parking meters are in effect during all Alive by the Bay festivals. The Town of Islip has released a FAQ guide to help navigate the metered parking. (No app is available yet to feed the meters remotely.)

• You can follow Alive by the Bay on Facebook.
