No. Check the attraction’s official calendar and hours before leaving.

Yes. Switch between a two-hour outing and a four-hour adventure to compare complete weather windows.

These are experimental editorial rules, not a trained model. We start at 100 and subtract 2.4 points per degree outside 60–80°F, 2 per mph above 12 mph, 0.65 per rain-chance point, and 1.4 per gust mph above 20. Feels-like temperature replaces air temperature when available. Half of a window’s rating comes from its average hour, half from its lowest-rated hour. Storm or wintry wording, or feels-like temperatures at or above 100°F or at or below 20°F, cap the window at Plan B weather. Great fit starts at 80, good fit at 65, and mixed bag at 45. Scores are comfort comparisons, not safety clearance.

Unknown rain, missing hours or forecasts older than 12 hours are not rated. NWS daytime flags limit these windows to forecast daylight; exact sunrise and sunset times are not calculated. No rating confirms that a venue is open.
