西奥多·罗斯福国家公园 5月 天气

Forum posters describe May temperatures as genuinely variable - typical early-to-mid-May highs in the upper-60s to low-70sF with lows in the low-40sF, though some years run cooler with 50sF highs and rain. One visitor described the month as dramatic and colorful in both landscape and weather within a single trip: calm and sunny one stretch, then cloudy, windy with a tornado watch, then rainy with hail. Posters warn a freak late-spring snowstorm remains possible even into early June in some years, though any snow that does fall tends to melt off quickly. On the upside, May sits in shoulder season with noticeably lighter crowds than the late-May-through-early-September peak, and wildlife is reported to be out in full force.

Theodore Roosevelt-forum threads on a January visit describe average conditions as genuinely cold, posters naming a typical high around twenty-eight degrees Fahrenheit and a low near five. Regulars call the park under snow genuinely even more beautiful, one visitor returning specifically for this look and spotting bison, elk and deer during the trip. Posters call wildlife genuinely still active through January, several regulars naming easier spotting against snowy terrain as a real upside of a winter visit. Regulars call a four-wheel-drive vehicle genuinely recommended, several threads naming snow-covered roads with occasional icy spots as standard this time of year. Posters recommend real winter preparation regardless of how mild the forecast looks, several regulars calling this standard given how quickly conditions can turn here. The record: -2.5C days, -15.1C nights, 9.8mm across over 3 days and 72 percent humidity.

Theodore Roosevelt-forum threads and park notices on a December visit describe both Units as staying open through the holidays, posters noting reduced visitor center hours and a closed Painted Canyon overlook as the main seasonal changes. Regulars call December through February the coldest stretch, average lows in the single digits Fahrenheit cited repeatedly across winter threads. Posters recommend a four-wheel-drive vehicle for a December trip, several regulars describing roads as covered with stronger winds capable of temporarily closing sections. Regulars call much of Medora shut this time of year, though the parts that stay open are described as genuinely welcoming to the handful of winter visitors. Posters recommend a real survival kit regardless of a clear forecast, several threads calling conditions here capable of turning brutal with little notice. The record: 0C days feeling like -5C, -13C nights, 19.2mm across 4 days and 69 percent humidity.

Theodore Roosevelt National Park-forum threads on an October visit recommend earlier in the month over later, posters calling an early snowstorm a real possibility once the month runs on. Regulars call the park genuinely quiet throughout October, a real contrast with the busier summer months. Posters recommend the Painted Canyon Nature Trail, Skyline Vista, Wind Canyon, Boicourt Trail and Buck Hill in the South Unit, with Caprock Coulee and Sperati Point the standouts in the North Unit. Regulars call daylight noticeably shorter by October, sunrise around seven and sunset near six-twenty leaving roughly twelve usable hours. Posters recommend real cold-weather layers regardless of a mild-looking forecast, conditions here capable of turning fast this late in the season. The record: 14.1C days feeling like 13C, -0.8C nights, 32.1mm across over 4 days and 61 percent humidity.

Theodore Roosevelt-forum threads on a February visit are direct this sits deep within a genuinely harsh North Dakota winter, real cold-weather gear non-negotiable regardless of how clear the sky looks. Posters describe daytime readings as staying well below freezing most of the month, exposed badlands terrain offering little shelter from the wind. Regulars call accumulation and drifting a standing feature of the season, some roads and overlooks less reliably accessible than in warmer months. Posters recommend checking current conditions before a winter trip, weather here capable of shifting fast with little warning. Regulars describe the badlands landscape as genuinely striking under a fresh layer, a real reward for visitors prepared for the cold. Posters call the near-total absence of crowds a genuine upside for anyone willing to brave the conditions. The record: -3.6C days feeling like -9C, -16.3C nights, a notably high 16cm of fresh accumulation and 66 percent humidity.
