If you go

What: Spruce Pool opened Monday with limited hours.

More info: The schedule for Spruce Pool is available at BoulderParks-Rec.org. Regular hours will begin May 28.

Dozens of teenagers and pre-teens with the Boulder Swim Team lathered on sunblock Monday afternoon before diving in to the outdoor swim season at Spruce Pool.

"It's so much nicer to be swimming outside than being cooped up in an indoor pool," said 17-year-old Sara Nash, a Legacy High School student on the swim team.

The opening of Spruce Pool and the weather in Boulder seemed to be on the same page. The high in Boulder on Monday hit 84 degrees, said meteorologist Matt Kelsch. The record high for the day is 89 degrees, set in 1988.

Tuesday is expected to be in the 80s but won't likely reach the record high of 88 degrees that was set in 1996, Kelsch said.

Each of Spruce Pool's eight lanes filled up with two to three swimmers throughout most of the afternoon, said Jayson Swigart, a facility manager for Boulder's Parks and Recreation Department.

"The weather definitely cooperated," Swigart said.

Boulder's Spruce Pool, 2102 Spruce St., was the first city pool to open up this year. The pool started the season with a limited schedule, and regular hours will begin May 28.

Typically, Scott Carpenter Pool, at 1505 30th St., is the early opener, but it's getting a paint job and some maintenance work done that had been delayed due to recent rain and snowstorms. Scott Carpenter will open up after Memorial Day weekend, and the city will soon announce a specific opening date for the pool.

Natalie Litke, pool manager at Spruce, is back from college in Greeley for her seventh season of lifeguarding.

"What is there not to love? I'm in the sun all summer long," she said.

And while Monday certainly felt like summer, she pointed out that the trees still have yet to bud and a snowstorm ushered in the month of May just a couple of weeks ago.

ZheniaThomas sat on the side of the pool as her two young daughters played with squirt guns and water toys.

"We'll be spending our whole summer here," she predicted.

Over at Lindsay's Boulder Deli on Pearl Street, business was booming with employees getting an arm workout and scooping lots of ice cream.

"We joke we all have one Popeye arm," said employee Kira Sadighi.

Tuesday is "free cone day" at the deli, 1148 Pearl St., where customers can get a free kid's cone.
