How parks & weather affect each day’s games
Park factors measure how a specific ballpark affects offensive production compared to league average. A factor above 1.00 (shown as a positive percentage) means the park boosts that stat, while below 1.00 (negative) means it suppresses it.
Wind blowing out toward the outfield helps carry fly balls for more home runs and extra-base hits. Higher temperatures make baseballs travel farther. Dome and retractable-roof stadiums neutralize weather effects when the roof is closed.
Arrows show the direction the wind is blowing toward. More arrows indicate stronger wind. Wind blowing outward (toward CF/RF/LF) favors hitters, while wind blowing in suppresses fly-ball production.
Look for matchups where park + weather combine to significantly boost or suppress scoring. Parks with large positive run factors favor game overs and run-scoring props. Parks with negative factors favor unders and pitching props. Always combine with pitcher matchup analysis.
