Weather Outlook: Toronto Blue Jays vs Seattle Mariners

The Toronto Blue Jays vs Seattle Mariners showdown on October 17, 2025, at T-Mobile Park in Seattle, WA, promises an indoor spectacle. As a retractable dome venue, T-Mobile Park shields the action from external weather swings. Fans tuning in on fox sports 1 can expect a comfortable environment with roof closed, even though the external forecast shows clear skies to partly cloudy conditions and temperatures hovering around 58–606F.

Seattle enters with a 30-20 home record, thriving in familiar surroundings. Toronto has gone 25-25 on the road, showing flashes of excellence but also vulnerability away from Rogers Centre. Historically, both teams have had mixed results under inclement weather, but the controlled dome reduces any edge from wind or precipitation.
