MLB Weather Report — September 11, 2026
Friday’s MLB slate is mostly in good shape, with no major postponement threat showing in the early forecast. Atlanta carries the most notable combination of warmth, humidity, rain potential and wind blowing out. Minnesota, Sacramento and San Francisco also have winds worth monitoring, while the remaining outdoor games currently project as mostly neutral.
PITTSBURGH PIRATES @ CHICAGO CUBS
Temperatures should be around 75 degrees with humidity near 37% and virtually no chance of rain. Winds are projected around 8 mph as a crosswind with a slight blowing-in component.
BETTING IMPACT
The wind is not strong enough to create a major Wrigley Field adjustment. Conditions lean slightly pitcher-friendly, but there is no significant weather edge.
COLORADO ROCKIES @ DETROIT TIGERS
Game-time temperatures should be around 74 degrees with humidity near 59% and no meaningful rain threat. Winds are expected around 6 mph as a crosswind.
Weather should not be a factor.
LOS ANGELES ANGELS @ WASHINGTON NATIONALS
Temperatures should be close to 78 degrees with humidity around 73%. Rain probability is approximately 1%, with light winds around 4 mph carrying a slight blowing-in component.
The warm and humid air could help the ball marginally, but the light wind keeps the overall weather impact neutral.
NEW YORK METS @ NEW YORK YANKEES
Temperatures should be near 76 degrees with humidity around 38% and no rain expected. Winds are projected around 5 mph as a crosswind.
No meaningful weather edge.
BALTIMORE ORIOLES @ TORONTO BLUE JAYS
Rogers Centre has a retractable roof, making the final roof decision more important than the outside forecast. Conditions should remain controlled if the roof is closed.
Weather should not affect the game if played under the roof.
KANSAS CITY ROYALS @ BOSTON RED SOX
Temperatures should be around 72 degrees with low humidity near 29%. No rain is expected, and winds should remain light at approximately 5 mph as a crosswind.
Conditions are comfortable and mostly neutral for hitting and pitching.
HOUSTON ASTROS @ TAMPA BAY RAYS
Tropicana Field is an enclosed stadium with controlled indoor conditions.
Weather will not be a factor.
LOS ANGELES DODGERS @ MIAMI MARLINS
LoanDepot Park has a retractable roof and climate-controlled conditions. The roof decision should eliminate any meaningful outdoor weather impact.
No weather edge.
PHILADELPHIA PHILLIES @ ATLANTA BRAVES
Temperatures should be around 79 degrees with humidity near 68%. Rain probability is approximately 28%, and winds are projected around 14 mph blowing out toward center or left-center field.
BETTING IMPACT
This is the strongest hitting-weather setup on the early slate. Warm, humid air combined with a double-digit wind blowing out could improve carry. There is also enough rain potential to require another check closer to first pitch, although the current forecast does not indicate a clear postponement threat.
CINCINNATI REDS @ MILWAUKEE BREWERS
American Family Field has a retractable roof. Weather impact will depend on whether the roof is open, but indoor conditions would eliminate any meaningful concern.
No weather edge if the roof is closed.
CLEVELAND GUARDIANS @ MINNESOTA TWINS
Temperatures should be around 78 degrees with humidity near 44% and no rain expected. Winds are projected around 13 mph blowing out toward center or left-center field.
BETTING IMPACT
The wind provides some help to hitters, although the moderate humidity prevents this from becoming an especially strong offensive environment. It is a secondary Over consideration rather than a major weather edge.
CHICAGO WHITE SOX @ ST. LOUIS CARDINALS
Temperatures should be near 77 degrees with humidity around 77%. Rain probability is approximately 6%, with light winds around 5 mph working as a crosswind with a slight blowing-in component.
The humidity is favorable for carry, but the light wind and minimal rain threat leave the overall weather impact close to neutral.
SEATTLE MARINERS @ ATHLETICS
Temperatures should be around 79 degrees with humidity near 40% and no rain expected. Winds are projected around 9–10 mph blowing out toward center field.
BETTING IMPACT
The warm temperature and wind blowing out provide a modest boost to hitters, but the dry air keeps this from becoming a strong weather-driven Over spot.
TEXAS RANGERS @ ARIZONA DIAMONDBACKS
Chase Field has a retractable roof and controlled indoor conditions. The roof decision will determine whether the outside heat has any influence on the game.
No meaningful weather edge if the roof is closed.
SAN DIEGO PADRES @ SAN FRANCISCO GIANTS
Temperatures should be around 62 degrees with humidity near 78%. Rain probability is approximately 2%, while winds could reach 17–18 mph blowing out toward right or right-center field.
BETTING IMPACT
The wind is strong enough to help balls hit toward right field, but Oracle Park’s cool marine air and deep dimensions can offset part of that advantage. This is a meaningful wind to monitor, but it does not create an automatic Over play.
BOTTOM LINE
Atlanta is the primary weather game to monitor because of the warm, humid conditions, rain potential and wind blowing out around 14 mph. Minnesota and Sacramento offer moderate hitting boosts, while San Francisco has the strongest wind but also the coolest temperatures and a park that can limit its impact. No game currently carries a major postponement threat, and no weather-based opinion needs to be forced outside the most notable wind spots.
