How these scores work
- Crowds — how far a month sits below the park's busiest month in the visitation records. The peak month scores 0, a month with half the peak's visitors scores 50.
- Weather — 100 when the average daytime high lands in the 55–75°F comfort band, falling 3 points per degree outside it. Months averaging 95°F or hotter are capped at 20, nights below 15°F cost 15 points, months averaging over 4 inches of rain lose up to 20, and months that are both hot (85°F+) and soaked (6 inches+) lose another 25 — the sticky-season penalty.
- Daylight — hours of daylight at the park's latitude, scaled from 8 hours (0) to 16 hours (100).
- Roads & access — typical monthly snowfall where the weather station reports it (25 inches or more scores 0); where it doesn't, how far average highs sit below 40°F stands in. This carries real weight by default because an empty month is often empty for a reason — mud season shouldn't win on crowds alone. Months with almost no recorded visits are treated as closed and score 0 here, and a near-empty month right next to the closed season gets access capped low — that quiet usually means the services are shut too.
- A park page blends crowds 30%, weather 40%, daylight 10%, roads & access 20%. Scores are shown as bands — Excellent (77+), Good (52–76), Tough (under 52) — never as decimals, because 30-year normals don't support false precision.
