Think it rains a lot in Seattle? You’re not wrong.

A new study by FlashPicks, a betting tips and predictions site, has confirmed what Mariners fans have known for years: without the retractable roof, T-Mobile Park would be a soggy sanctuary for the home team.

FlashPicks ranked all 30 MLB stadiums based on various factors, including rainfall. With Seattle averaging over 150 rainy days rainfall annually the study found that the Emerald City would be the joint fourth-wettest stadium in the MLB – well, at least outside of the closed roof. 

While Seattle might have more rainy days then some other MLB cities, that doesn’t mean that it’s the wettest.  If you’ve been around long enough, you know that the rain here can torment you with its constant drizzle.  Other cities like Miami – home to LoanDepot Park and the Marlins – see 10 fewer days of rain, but it packs much more of a punch dropping more than 67 inches of the wet stuff per year. No doubt a factor when they also built their stadium with a retractable roof.

When it rains…

If you’re a Cleveland Guardian fan you may want to bring an umbrella along with you. With an average of 159 days or rain per year adding up to 41 inches, there is no retractable roof at Progressive Field to keep the fans or players dry.  But, sitting on top of the AL Central, it clearly isn’t affecting their play.

With all of these rain counts, it’s surprising that there are not more weather delayed games. And it’s surprising that there are not more than seven Major League Baseball stadiums with retractable roofs (plus one fixed dome roof at Tropicana Field, home of the Tampa Bay Rays). 

Glad to count T-Mobile Park in Seattle as one of the seven. Here’s to the Mariners keeping dry and keeping their lead over the AL West pack, post-All Star break.
