MLB ballpark weather: wind, temperature and totals

For today's slate specifically, the wind blowing out MLB tracker groups every ballpark by whether the first-pitch wind is carrying out to centre, blowing in, or crossing — measured against each park's own field bearing.

The single most useful number in baseball weather is where the wind is going relative to home plate, not how hard it is blowing. A 12 mph wind straight out to centre can add meaningful distance to fly balls. The same 12 mph blowing in turns those balls into routine outs.

Cross-winds are the trickiest case: they push balls toward one foul line, which can matter a lot in asymmetric parks. On the MLB dashboard each ballpark shows a wind arrow drawn against the actual stadium orientation, so you can see whether the wind is out, in or across for that specific field.

Warm air is thinner and offers less drag. As a rough guide, hotter games trend toward more run scoring and cold games trend the other way — an April night in the 40s°F plays very differently from a July afternoon in the 90s°F at the same park.

Altitude compounds this. Coors Field sits about a mile above sea level, where thin air both adds carry and flattens breaking pitches. That is why its totals are structurally higher than anywhere else in the league before weather is even considered.

Wrigley Field is the classic. Lake Michigan winds swing the park between a bandbox and a pitcher's park within the same week — the reason "Wrigley weather" is one of the most searched terms in baseball.

Oracle Park gets cold marine air and a wind that typically knocks down balls to right. Fenway Park has the Monster interacting with wind off the harbour. Coors Field is altitude-first.

Roofed and retractable parks — Tropicana, Rogers Centre, Chase Field, Minute Maid, Globe Life, loanDepot, American Family, T-Mobile — mostly neutralise weather. If the roof is shut, treat the game as indoor and move on.

A practical read stacks the three drivers in order: wind direction first, temperature second, precipitation and humidity third. Two or three factors pointing the same way is a real signal. One mild factor on its own usually isn't.

OverUnderWeather does this read for you. Each ballpark gets live conditions from a professional forecast feed, a Weather Edge Score, and a plain-English Weather Lean — Over, Under or Neutral — with the reasoning shown so you can disagree with it.
