Unlock the Full SheetTwo identical matchups can have wildly different outcomes depending on where and when they are played. A game at altitude in July with wind blowing out plays like a different sport than a cold April night in a pitcher's park. Yet most bettors evaluate players and teams while treating the environment as an afterthought.
Our daily report quantifies it: each park's baseline factors (runs, home runs, strikeouts) adjusted for the day's actual forecast — temperature, humidity, wind speed and direction relative to the park's orientation, and roof status. The output is a same-day percentage shift for runs, homers, and strikeouts in every game.
The best use is as a multiplier on your other angles: it turns a coin-flip home run prop into a clear bet or a clear pass, and it flags the slates where game totals have not caught up to a weather change.
Park factors measure how much a ballpark inflates or suppresses offense compared to a neutral field — driven by wall distances and heights, foul territory, altitude, and typical weather. Coors Field famously boosts runs; pitcher parks like T-Mobile Park suppress them.
Warm air is less dense, so fly balls carry farther — roughly 3-4 feet per 10°F. Wind matters even more: a 10 mph wind blowing out can add double-digit percentage points to HR probability, while wind blowing in does the opposite. Our report combines each park's dimensions with the day's forecast at game time.
Use it as an environment filter on top of your player and team angles. A borderline home run prop becomes attractive in a +15% HR environment and unplayable in a -10% one. The same logic applies to game totals, NRFI/YRFI bets, and strikeout props (weather affects breaking ball movement less than carry).
