MLB Weather Report — September 16, 2026
The main weather concerns are scattered thunderstorms in Pittsburgh and Colorado, with Chicago and Cleveland also worth monitoring. No game is currently classified as a likely delay or rainout. The warmest hitting conditions are expected in St. Louis and Cincinnati.
WHITE SOX @ GUARDIANS
Temperatures should remain in the upper 70s with humidity around 80–85%. There is a 20–30% chance of rain with a 5–8 mph crosswind.
No meaningful wind edge, but a passing shower could create a brief delay.
GIANTS @ CARDINALS
Temperatures should begin near 90 degrees and climb into the low 90s. Humidity will be around 60%, with a 10–15% chance of rain and a 5–6 mph wind blowing out.
BETTING IMPACT
The heat is the biggest factor. Warm air and a light wind blowing out should provide favorable conditions for hitters.
YANKEES @ TWINS
Temperatures will be in the upper 60s to low 70s with humidity around 55%. No rain is expected, and the wind should be a 6–8 mph crosswind.
No meaningful weather edge.
TIGERS @ BLUE JAYS (INDOORS)
DODGERS @ REDS
Temperatures should be in the low 90s with humidity between 55–65%. The rain chance is around 10–15%, with a light 1–4 mph crosswind.
BETTING IMPACT
The hot air could provide a small boost to ball carry, but the light wind does not create a major edge.
ATHLETICS @ RAYS (INDOORS)
BREWERS @ PIRATES
Temperatures should be in the low-to-mid 80s with humidity between 70–80%. The chance of scattered thunderstorms is approximately 30–45%, with a light 2–4 mph wind blowing out.
BETTING IMPACT
This is one of the main games to monitor. A delay is possible if a storm reaches the ballpark, although there is no current indication of a likely postponement.
PHILLIES @ NATIONALS
Temperatures will be in the low-to-mid 80s with humidity around 50–55%. Rain is unlikely, and a 6–7 mph wind should blow out toward left field.
BETTING IMPACT
Warm conditions and a modest wind blowing out create a slightly favorable environment for hitters, but the wind is not strong enough to make this a major weather play.
ORIOLES @ METS
Temperatures should remain in the mid-70s with humidity around 70%. The rain chance is below 5%, with a 7–9 mph crosswind.
Weather should not be a factor.
BRAVES @ CUBS
Temperatures should be around 70 degrees with humidity near 90%. There is a 20–30% chance of rain, with a 6–8 mph wind blowing in.
BETTING IMPACT
The wind blowing in at Wrigley should reduce ball carry and creates a slight pitcher-friendly lean. Scattered rain is also possible, so conditions should be checked closer to first pitch.
RED SOX @ RANGERS (INDOORS)
ROYALS @ ASTROS (INDOORS)
PADRES @ ROCKIES
Temperatures should be in the upper 70s to low 80s with humidity between 35–45%. The chance of scattered thunderstorms is approximately 30–45%, with a 6–10 mph crosswind.
BETTING IMPACT
Colorado is another important game to monitor for possible delays. The wind direction is variable and does not currently provide a dependable betting edge.
MARINERS @ ANGELS
Temperatures should remain in the low-to-mid 70s with humidity around 70%. No rain is expected, and the wind should blow out at 8–10 mph before easing later in the game.
BETTING IMPACT
The wind blowing out could provide a modest boost to ball carry, especially during the early innings.
MARLINS @ DIAMONDBACKS (INDOORS)
BOTTOM LINE
Pittsburgh and Colorado are the primary delay watches, while Chicago and Cleveland deserve secondary attention. St. Louis and Cincinnati offer the warmest hitting conditions. Chicago has the clearest wind-in setup, while Anaheim has the strongest wind blowing out. There are no games currently expected to be postponed, but Pittsburgh, Colorado and Chicago should be checked again closer to first pitch.
