カカドゥ国立公園 1月の天気

Forum posters describe January as deep in Kakadu's wet season, with average rainfall exceeding 420mm and the potential for it to rain all day, every day if the monsoon is actively in - conditions posters describe as extremely hot and humid, with humidity commonly near 100%. Posters do note a real upside: when rain does fall, it noticeably cools things down and can feel genuinely refreshing rather than just uncomfortable. Posters are consistent that road access remains largely workable during the Wet, with only specific spots like Twin Falls and Jim Jim Falls closing due to gravel roads and creek crossings - posters generally recommend joining a small-group tour rather than self-driving to navigate the trickier sections, with Yellow Water Cruises specifically confirmed as running throughout the wet season.

Kakadu-forum threads on a February visit are direct: this is genuinely the wettest month of the year, posters calling roughly 320 millimeters of rain typical and humidity high enough that sleeping comfortably can be a real challenge without air conditioning. Regulars call a portion of the park inaccessible this time of year, swollen rivers and muddy roads cutting off usual sites. Posters recommend boat cruises out of Cooinda or Jabiru as a genuine highlight, the Yellow Water cruise reaching areas that stay underwater this season. Regulars call February possibly the toughest month logistically, though there's still real value staying flexible around daily-changing conditions. Posters recommend checking current road status rather than a fixed itinerary. Regulars call the waterfalls and lush landscape a genuine reward for anyone willing to adapt. The record: 34.1C days feeling like a punishing 40C, 24.9C nights, an extraordinarily high 352.7mm across over 18 days and 82 percent humidity.

Kakadu-forum threads on April describe this as still genuinely wet season, posters calling the rains tapering off but far from finished, water levels only slowly receding as the month goes on. Regulars call several tracks still closed, crocodiles needing to be cleared from some sites before access reopens, a real safety consideration rather than bureaucratic caution. Posters describe some spots normally 2WD in the dry season as requiring 4WD in April due to creek crossings still running. Regulars call humidity genuinely high overnight, uncomfortable sleeping a real complaint from anyone camping rather than staying in air-conditioned accommodation. Posters recommend checking current road and track status with the visitor center before a route. Regulars call the landscape genuinely green and striking despite the access limitations. The record: 35.1C days feeling like a punishing 38C, 24.4C nights, 79.8mm across over 5 days and 66 percent humidity.

Kakadu-forum threads on a March visit call conditions genuinely hot and humid, posters describing this as still deep within the region's heavier system season even as the calendar edges toward the settled months. Regulars call February and March typically the wettest stretch of the year, real flooding a standing possibility that can close off entire sections of the park. Posters recommend confirming current road status, four-wheel-drive tracks routinely closed through this window regardless of the forecast for a specific day. Regulars describe scenic flights and boat trips as reliable alternatives when ground routes are impassable. Posters call the landscape genuinely lush and green, waterfalls off the escarpment often still running strong. Regulars recommend real caution around waterways given how far crocodiles range once levels rise. The record: 34.8C days feeling like a punishing 41C, 25.1C nights, an extraordinarily high 248.6mm across over 15 days and 79 percent humidity.

Kakadu-forum threads on late May confirm this sits right at the start of the dry season, still ahead of the main tourist rush, posters describing it as genuinely comfortable though occasionally warm and humid rather than fully settled cool-season conditions. A real advantage of this early window is the amount of water still flowing over the park's major waterfalls, fed by the tail end of the previous wetter stretch, before levels drop through later months. Most of the park is reported accessible to a standard 2WD vehicle by late May barring an unusually heavy recent system, though posters recommend checking road status before the more remote unsealed routes. Regulars call the balance of good access, flowing waterfalls and thinner crowds a genuine sweet spot against the busier, drier peak later in the season. Sun protection remains essential regardless of season. The record: 33.9C days feeling like a punishing 38C, 22.7C nights, 53 percent humidity and 9.6 hours of sun.
