バッドランズ国立公園 5月の天気

Badlands' forum calls late May pleasant for hiking, highs in the low-to-mid 60s°F and lows in the low-to-mid 40s°F, genuinely better for trails than the July heat. Regulars are candid that May weather here is 'anyone's guess' — capable of windy, rainy, even a little snow mixed in — but reward includes more active wildlife and fewer crowds than peak summer.

Badlands-forum threads on a March visit describe snowstorms as a genuine possibility, posters naming late March into early April as when a real blizzard often hits. Regulars call average nighttime lows genuinely around twenty-six degrees Fahrenheit, several posters naming this standard cold for the month regardless of daytime conditions. Posters call the main loop road genuinely still open barring a big storm, several regulars naming Needles Highway and Iron Mountain Road nearby as staying closed until mid-April instead. Regulars call RV camping genuinely something most visitors avoid before Memorial Day, several threads naming cold nights as the real reason to wait for warmer months. Posters recommend real flexible plans and winter gear for a March visit, several regulars calling this standard given how quickly a blizzard can move through. The record: 10.3C days, -4.1C nights, 31.3mm across nearly 5 days and 62 percent humidity.

Badlands-forum threads on a February visit describe January and February weather as genuinely capable of turning nasty, posters calling this a real factor for anyone combining a Badlands stop with nearby Mount Rushmore or Jewel Cave. Regulars call Mount Rushmore's visibility a real gamble this time of year, fog sometimes obscuring the monument even on an otherwise clear-seeming day. Posters call the park itself generally accessible in February despite the cold, though conditions here shift enough that checking directly before setting out is worthwhile. Regulars recommend combining a Badlands stop with a Mitchell base for anyone driving through the region, a few hours' detour considered manageable for a weekend trip. Posters recommend real winter layers regardless of how the forecast looks that morning, conditions here changing fast on the open plains. The record: 3.2C days feeling like 1C, -10.4C nights, 13.5mm across over 3 days and 55 percent humidity.

Badlands-forum threads on a January or February visit call the weather potentially genuinely nasty, posters describing conditions as capable of swinging from a pleasant sunny day to a real blizzard within the same week. Regulars call the park open year-round, the loop road and overlooks accessible whenever conditions allow safe driving. Posters describe wildlife sightings as hit-or-miss even in warmer months, winter adding real unpredictability on top of that. Regulars recommend checking current road and weather conditions before the drive, a storm here capable of closing routes with little warning. Posters call a clear winter day genuinely spectacular, the eroded formations and layered rock taking on a stark character under a low winter sun. Regulars recommend real cold-weather layers regardless of forecast, wind chill here turning brutal fast once a front moves through. The record: 2.3C days feeling like -3C, -10.6C nights, 10.1mm across over 2 days and 67 percent humidity.

Badlands-forum threads on September visits call this a genuinely strong month, thinner crowds once kids return to school and a real drop in the odds of an afternoon thunderstorm compared to midsummer. Posters describe early September as still capable of running warm, while mid-month regulars call the sweet spot for temperatures settling into the comfortable fifties and sixties Fahrenheit. Regulars call lower lodging prices a genuine bonus of visiting after Labor Day, availability noticeably easier without the summer rush. Posters recommend an early or late-day visit for the best light on the eroded formations, midday sun called harsh for photography. Regulars describe wind as a real constant here across seasons, worth factoring into any exposed hike or overlook stop. Posters call September a real favorite for the combination of comfortable conditions and low crowds. The record: 27.2C days feeling like 25C, 10.8C nights, 54 percent humidity and 10.3 hours of sun.
