# MLB Weather and Ballpark Run Environment Dataset for Total Research

**Question this dataset helps answer:**
Which MLB weather and ballpark contexts historically align with higher or lower run environments before building totals, DFS, or fantasy research workflows?

This dataset helps totals researchers, fantasy baseball analysts, and sportsbook-market researchers compare MLB run environments using first-pitch weather, ballpark dimensions, roof context, field-oriented wind components, local start time, and rolling team scoring context.

**Use the public sample to check:**
- Which parks, roof types, and weather-station matches are represented in the preview
- Which columns are pregame weather or rolling-context features versus postgame scoring outcomes
- Which temperature, wind, and run-environment combinations appear in the sample before buying the full file

**Preview vs full dataset:**
- Preview: 1200 rows and 84 columns
- Full: 24005 rows and 84 columns

This product is built around a recurring workflow problem that sits between sports betting research, fantasy baseball, and dashboard analysis. Daily MLB weather pages are widely used, but most of them are ephemeral. They help with today's slate, not with historical comparisons across seasons, parks, roof types, wind directions, and scoring environments. Buyers who want to answer questions about totals or run context usually have to rebuild the same stack from scratch: MLB schedules, venue metadata, roof status, local start times, weather observations, and team trend features. This dataset packages that structure directly into a single reproducible table.

Each row represents one completed MLB regular-season game. The coverage runs from April 3, 2016 through June 10, 2026 and includes 24005 game rows across 84 columns. That row count matters. It is large enough for filtering by team, park, month, roof type, first-pitch weather regime, and rolling team form while still retaining meaningful sample sizes. Buyers can use the file for historical dashboards, weather segmentation, park-level comparisons, or time-aware modeling without first spending hours rebuilding raw sources.

The pregame side of the table is built around the weather-and-context problem that buyers already care about. Key feature groups include venue identity, park dimensions, roof type, local start hour, nearest-station weather provenance, first-pitch temperature, humidity, precipitation, wind speed, wind gusts, wind direction, field-oriented wind-out and crosswind components, barometric pressure, cloud cover, team rest gaps, and rolling team offense or defense features. That combination is the unique angle. A generic baseball game log might show only teams and scores. This file adds the context buyers actually search for when they want to compare run environments across parks and weather setups.

The ballpark orientation piece makes the dataset more useful than a raw weather merge. Instead of stopping at wind direction alone, the build converts the weather-station wind reading into a park-aware component that estimates whether the wind was blowing out toward center field or across the field. That gives buyers a better research surface for questions like whether warm temperatures with outward wind at specific parks line up with higher scoring environments more often than cooler or inward-wind setups. It also makes the sample easier to understand because the park-and-wind relationship is explicit in the schema rather than hidden in a manual notebook transformation.

Rolling team features help separate short-term form from environment. The dataset includes pregame rolling averages for runs scored, runs allowed, total runs, hits, and win rate, plus season-to-date runs scored and allowed averages for both home and away teams. Those fields make the dataset useful beyond weather-only filtering. A buyer can study whether a high-scoring outcome came from a hot offense entering a favorable weather window, a struggling pitching environment, or a combination of both. That is closer to the real workflow than simply sorting games by temperature.

The postgame side of the table stores the actual results. Those result columns include home and away score, total runs, run differential, hits, errors, and home-team win outcome. That separation matters. It keeps the pre-event columns usable as responsible research features while preserving the actual game outcome as a target for comparison. The schema therefore supports both descriptive dashboard work and exploratory modeling workflows that need a clean line between information available before first pitch and information only known after the game ended.

Weather coverage is intentionally transparent rather than overstated. Hourly weather is matched through the nearest public station, and the dataset includes weather station identifiers, names, and approximate distance from the venue. That provenance matters when a buyer wants to assess the credibility of a historical weather match at a retractable roof park, a downtown stadium, or an international venue. Some rows may have missing weather because the nearest public station did not provide a clean hourly match at the exact rounded first-pitch time, but the row still retains useful park and team context. That is a better tradeoff than filling historical gaps with invented values.

## Responsible use note

This dataset is for research, analysis, dashboard building, educational use, and exploratory modeling. It does not provide betting advice, picks, guarantees, or predictions of future outcomes. It should not be marketed as a shortcut to guaranteed profit, and it should not be interpreted as proof that any single schedule angle automatically creates an edge.

## Modeling notes

- Each row represents one completed MLB regular-season game.
- Pregame features include park geometry, roof type, local start hour, nearest-station hourly weather, rest gaps, and rolling team scoring context.
- Postgame outcomes include runs, hits, errors, run differential, and home-team win result.
- The coverage window runs from April 3, 2016 through June 10, 2026.
- The full dataset contains 24005 rows, which is large enough for train-test splits by season, by month, by park, or by pregame weather regime.
- A sensible modeling workflow would split by season or by date rather than shuffling randomly, because the product is time-ordered and season context changes.
- Weather is station-based rather than stadium-sensor-based, so buyers should treat the station-distance fields as part of data-quality assessment.
- Retractable-roof and dome parks remain useful analytical rows because the roof-type fields are explicit and filterable.
- The dataset is descriptive infrastructure, not a finished predictive system.

## Why the free sample matters

The public sample is not filler. It proves that the buyer task is real. A buyer can open the sample and immediately verify that the file contains first-pitch weather fields, park geometry, roof metadata, station provenance, rolling offense and defense context, and clear result columns. They can see whether the product answers the practical question they already have: how weather and ballpark context line up with historical scoring environments. That is exactly what a public discovery asset should do.

## Source and build notes

The build uses public MLB Stats API schedule and venue metadata plus public Meteostat station data, then engineers park-aware wind components and rolling team run-environment features locally. The process is reproducible, versionable, and does not depend on a private odds feed. The output is a single analysis-ready table rather than a loose collection of raw weather and schedule files that still need substantial cleaning and joins.
