With temperatures in the 90s and the heat index climbing into the triple digits this week, most adults in Suffolk are focused on spending their recreational time somewhere with a functional air conditioning system.

But fall is coming, along with cooler temperatures, and with it comes a window of opportunity to get outside again and burn off a little steam without the potential of suffering from heat stroke.

The Suffolk Department of Parks and Recreation stands ready to help.

Registration for the fall adult sports leagues offered by the city opened on July 18 and continues until Sept. 2. The city offers four different sports leagues for the fall season: co-ed volleyball, men’s softball, co-ed softball and co-ed kickball.

It’s no secret that the parks department offers great experiences for kids, but officials there are working to increase the availability of and knowledge about the organized activities available to adults, as well.

Last year, according to Recreation Manager Mike Frickanisce, interest in the adult leagues was light, so the department was forced to cancel the programs. They — and we — hope this year will be different.

Each of the four sports leagues requires players to register as a team, so players must organize their team before signing up. If each league has six teams sign up to play, it will be considered a success for Suffolk Parks and Recreation, Frickanisce said recently.

“Five teams would be good, because we would be able to have a double-elimination tournament and keep it fun,” he said. “I would be happy with five, but six would be a success.”

So get your kickball team together. Gather up some friends for volleyball. Or organize a small group of men from your church into a softball team. You’ll have some fun, and you’ll have a good reason to get outside and enjoy the cooler weather we’re all expectantly waiting for right now.

Registration has to be done in person at the Parks and Recreation administration building at 134 S. Sixth St. The team registration fee is $350 for co-ed and men’s softball, $175 for volleyball and $220 for kickball. Registration closes on Sept. 2.
