A cool wet summer is keeping Windsorites out of the pool, and money out of the pockets of installers.

Swimming lessons have been at normal levels at city pools but recreational swims aren't as crowded as usual and acting manager of aquatic services Scott Bisson blames the weather.

"Any time there's thunder or lightning we have to close our outdoor pools and we had one of the wettest July's on record here in Windsor," said Bisson. "Our recreational swimming numbers are down 25 per cent from this time last year."

New pool owner Bob Wallis agrees with Bisson's assessment wholeheartedly.

"You can't fool Mother Nature, I guess," said Wallis.

The retired paramedic has only had his pool since the end of April, but Wallis says he’s been relegated to "bug patrol" and other jobs to keep the pool clean for when the weather is nice enough.

He says when family and friends decide to take a quick dip – they jump in and get right out.

"We're just hoping the weather maybe this week will get a little nice for us, where we can have more use with the pool," Wallis said.

He hopes to keep the pool open until the middle of September, and then take it day-by-day.

It's also been quiet for the people who sell and install pools, according to Angelo Mariani of Pools by Angelo.

"We had a lot of demand at the beginning of the year, but the weather did make that big change for us," said Angelo

He said business has been down by about 20 per cent this year.

The rain kept his installers out of a lot of backyards because they were too wet, but he said they're catching up now.

Pool installations can run into mid-November so the veteran pool installer is hoping to salvage what's left of the season.

"Couple more months of hot weather would be excellent," he said.

Mariani says it's not too late to sell more pools and installations this year.

Good weather into the end of one season traditionally means more demand for new pools at the beginning of the next, according to Mariani.
