MLB Weather Update — September 13, 2026
COLORADO ROCKIES AT DETROIT TIGERS
78°F, partly cloudy with 63% humidity. Crosswind around 9 mph with almost no rain risk.
Betting impact: No meaningful weather edge.
PHILADELPHIA PHILLIES AT ATLANTA BRAVES
85°F, partly cloudy with 60% humidity. Crosswind around 8 mph. No rain expected.
Betting impact: Warm conditions, but the wind is not strong enough to create a significant total or home-run edge.
NEW YORK METS AT NEW YORK YANKEES
76°F with 87% humidity and a 64% chance of rain. Light wind blowing in around 6 mph.
Betting impact: Early rain could cause a delay, although conditions are expected to improve. Monitor radar before using starting-pitcher props.
LOS ANGELES ANGELS AT WASHINGTON NATIONALS
83°F, partly cloudy with 72% humidity. Light crosswind around 5 mph and a low rain risk.
Betting impact: No significant weather edge.
BALTIMORE ORIOLES AT TORONTO BLUE JAYS
(Indoors)
HOUSTON ASTROS AT TAMPA BAY RAYS
(Indoors)
LOS ANGELES DODGERS AT MIAMI MARLINS
(Indoors)
CLEVELAND GUARDIANS AT MINNESOTA TWINS
67°F and clear with 41% humidity. Wind blowing in around 9 mph.
Betting impact: Slightly pitcher-friendly conditions, but not enough to force an under.
CINCINNATI REDS AT MILWAUKEE BREWERS
(Retractable roof)
CHICAGO WHITE SOX AT ST. LOUIS CARDINALS
83°F, partly cloudy with 61% humidity. Light wind blowing in around 6 mph.
Betting impact: Warm temperatures are balanced by the light inward wind. No significant edge.
PITTSBURGH PIRATES AT CHICAGO CUBS
71°F, partly cloudy with 52% humidity. Crosswind from left to right around 12–15 mph. Low rain risk.
Betting impact: This is not the usual Wrigley wind blowing directly in or out. No strong total adjustment is warranted.
KANSAS CITY ROYALS AT BOSTON RED SOX
Around 70°F with 96% humidity and a 70% chance of rain. The first pitch was moved from 1:35 p.m. to 3:05 p.m. ET because of the weather.
Betting impact: This is the slate’s biggest delay and possible postponement concern. Rain may linger into the late afternoon, making starting-pitcher props risky until the radar becomes clearer.
SEATTLE MARINERS AT ATHLETICS
76°F and clear with 37% humidity. Light wind around 7 mph and no rain expected.
Betting impact: No meaningful weather edge.
TEXAS RANGERS AT ARIZONA DIAMONDBACKS
(Retractable roof)
SAN DIEGO PADRES AT SAN FRANCISCO GIANTS
Approximately 65°F with 74% humidity. Strong wind blowing out toward right-center around 15 mph, with gusts approaching 25 mph. No rain expected.
Betting impact: This is the strongest run-environment signal on the slate. The gusty outward wind could improve fly-ball carry and power, especially toward right-center field. Monitor the total and home-run markets.
BOTTOM LINE
Boston carries the greatest delay and postponement risk. San Francisco has the most significant wind conditions, with strong gusts blowing out toward right-center. The remaining outdoor games do not present a strong enough weather advantage to force an opinion.
