MLB Games to Monitor for Weather

Orioles at Yankees (1:05 p.m. ET)

Rain showers carry a 50% probability at first pitch and intensify sharply through the afternoon, reaching 83% by 2:00 p.m. and holding there through 5:00 p.m. Conditions worsen further into the evening as thunderstorms develop, with precipitation climbing to 98-99% after 6:00 p.m. The combination of persistent rain and 17-21 mph northeast winds creates conditions where multiple interruptions are likely. Postponement is a realistic outcome if the heaviest rain arrives on schedule.

Weather Timeline

  • 1:00-2:00 p.m. — Rain showers at 50% probability; game start may face a weather decision
  • 2:00-5:00 p.m. — Rain showers intensify to 83% with steady NE wind at 17 mph
  • 6:00-7:00 p.m. — Precipitation climbs to 98%; thunderstorms begin developing
  • 8:00 p.m. — Showers and thunderstorms at 99%; conditions at their worst

Rays at Phillies (3:05 p.m. ET)

Rain showers are likely throughout the game window, starting at 56% near first pitch and building to 79% by 6:00 p.m. and 90% by 7:00 p.m. No thunderstorms are currently forecast, but the steady, persistent rain makes at least one interruption likely. North wind at 15 mph adds to the difficult conditions. The game should attempt to start on time, but completing nine innings without an interruption appears unlikely given the building precipitation.

Weather Timeline

  • 3:00-4:00 p.m. — Rain showers likely at 56%; conditions workable for first pitch
  • 5:00-6:00 p.m. — Rain intensifies to 65-79% as the system deepens
  • 7:00-8:00 p.m. — Peak precipitation at 82-90%; highest interruption probability

Mets at Nationals (1:05 p.m. ET)

Light rain is likely at first pitch with a 65% probability, holding steady around 64% through 4:00 p.m. before gradually improving. The key factor is intensity: forecasts indicate light rain rather than heavy showers, which typically allows play to continue. Conditions should improve as the afternoon progresses, with rain chances dropping to 45% by 6:00 p.m. and 21% by 8:00 p.m. Northwest wind at 16-18 mph is notable but not extreme. A brief interruption remains possible during the early innings, though postponement appears unlikely given the improving trend.

Weather Timeline

  • 1:00-3:00 p.m. — Light rain likely at 64-65%; wind at 17-18 mph from the NW
  • 4:00-5:00 p.m. — Rain chances begin easing to 60-64%
  • 6:00-7:00 p.m. — Improvement continues; rain chances drop to 30-45%

DFS and Betting Weather Notes

Orioles at Yankees

Yankee Stadium faces the most disruptive weather on Sunday’s slate. The 17-21 mph northeast wind suppresses fly-ball carry, particularly to the short right-field porch that typically benefits left-handed power. Combined with persistent rain, this environment leans heavily pitcher-friendly when play is active. DFS players should avoid stacking this game given the realistic postponement risk. Bettors should monitor weather closely before first pitch; the combination of suppressed offense and potential for a shortened game creates an under-friendly environment if the game is played.

Rays at Phillies

Citizens Bank Park’s normally hitter-friendly environment faces a significant downgrade with steady rain and 15 mph north wind throughout the afternoon. The rain risk creates lineup uncertainty for DFS, as any interruption could affect bullpen usage and shorten starter outings. North wind at Citizens Bank Park acts as a crosswind that limits the park’s typical offensive boost. Consider fading this game in DFS tournaments and monitoring weather updates before locking in bets.

Mets at Nationals

Light rain and 16-18 mph northwest wind at Nationals Park create a modest weather factor worth noting. The wind could slightly improve fly-ball carry, partially offsetting the damp conditions. The improving forecast trend later in the game means weather effects lessen as innings progress. This is not a game to avoid entirely, but DFS players should account for early-inning interruption risk when building lineups.


FAQs

How does rain affect baseball games?

Persistent rain affects baseball games differently depending on intensity. Light rain can reduce grip for pitchers and make the ball slippery, while heavy rain typically forces an interruption in play. Ground crews cover the infield during interruptions, and games are generally not called until at least five innings have been completed. Weather interruptions can disrupt pitcher rhythm and bullpen strategy, creating unpredictable game flow that affects both DFS and betting outcomes.

What wind speed affects MLB games?

Wind becomes a meaningful factor at speeds above 10-12 mph, with the most significant effects occurring above 15 mph. Direction matters as much as speed: outward wind enhances fly-ball carry and home-run potential, while inbound wind suppresses offense. Crosswinds can alter defensive positioning but generally have less consistent impact on scoring. Stadium orientation determines how a given wind direction translates into on-field effects, which is why ballpark-specific analysis matters.

How does weather affect MLB DFS lineups?

Weather creates both risk and opportunity in daily fantasy. Rain risk can shorten games or cause postponements, which caps player point ceilings and increases variance. Wind blowing out at hitter-friendly parks can boost home-run potential, making power hitters more attractive. Cold, rainy conditions tend to suppress offense and favor pitchers. Weather-sensitive ballparks like Wrigley Field and Coors Field see the most pronounced effects, making weather a critical variable for lineup construction.

Which MLB ballparks are most affected by weather?

Wrigley Field and Coors Field consistently show the strongest weather sensitivity in MLB. Wind at Wrigley can dramatically change offensive expectations from day to day. Coors Field’s elevation causes dry air to enhance ball carry beyond what happens at sea-level parks. Great American Ball Park, Citizens Bank Park, and Nationals Park are also weather-sensitive due to their open-air designs and locations in thunderstorm-prone regions. Retractable-roof stadiums largely eliminate weather as a factor when closed.
