クレーターレイク国立公園には5月のメモがまだありません — これは季節を共にする近くのベンドについてのメモです。
Regulars are specific about the geography behind this month's weather: sitting east of the Cascades, this town runs noticeably warmer and sunnier than Oregon's wetter west side during this transition into spring. Our row backs a real day/night swing, 19.3C by day over a cold 0C-feeling night, with 25.9mm of rain across 6.5 days and a trace of late snow, 2.2cm. Regulars note trail conditions can still be messy with leftover gravel and mud from winter well into the month, worth checking before a bike or hiking plan. Mid-month brings a major sporting event, the Pole Pedal Paddle, that draws thousands and is worth planning lodging around either way. The record: humidity 56 percent, 12.2 hours of sun, a 17.5 kph wind and AQI 39.
クレーターレイク国立公園のほかの月
Crater Lake-forum threads on a January visit describe Rim Drive and the north entrance as genuinely closed for the season, posters naming Rim Village as the only real place to view the lake this time of year. Regulars call the west and south entrances genuinely plowed daily and open year-round, several posters naming this the standard way in during winter. Posters call even the Rim Village road capable of closing in heavy snow, several regulars naming chains as standard equipment for anyone driving up in January. Regulars call roughly forty feet of snow a year genuinely typical here, several threads naming this the reason so much of the park stays inaccessible without snowshoes. Posters recommend checking current road status before a January trip, several regulars calling this standard given how quickly conditions can close even the plowed sections. The record: 1.5C days, -5.8C nights, an extraordinarily high 259.1mm across 17 days and 84 percent humidity.
Crater Lake-forum threads on a November visit describe the north entrance as typically closed by early in the month, posters calling the south entrance the only realistic access point through the rest of autumn and into winter. Regulars call tire chains a real possibility depending on conditions, a genuine complication for anyone in a rental car since chains often aren't permitted on them. Regulars call Rim Drive closed by November, the lake itself still viewable from accessible overlooks despite the more limited access. Posters call both in-park lodges closed for the season by this point, Klamath Falls or Fort Klamath the practical nearby options instead. Regulars recommend checking current road conditions directly before a November trip, forecasts here considered genuinely unreliable this late in the year. The record: 4.9C days feeling like 3C, -3.3C nights, an extraordinarily high 193.3mm across over 13 days and 78 percent humidity.
Crater Lake-forum threads on October weather describe the month as genuinely transitional, posters calling the first half often still pleasant, t-shirt weather by day with just a light layer needed once the sun drops. Regulars call the back half of the month a different story entirely, winter conditions typically setting in with real snowfall common by late October. Posters describe the lodge as closing for the season around mid-month, boat tours and the trolley having already wrapped up back in September. Regulars recommend checking current road and facility status directly before planning a visit this late in the month, conditions capable of shifting within days. Posters call the lake itself worth the trip regardless of exact timing, the rim views striking under October's clearer, quieter skies. Regulars recommend real layers for the genuinely cold evenings at this elevation. The record: 10.5C days feeling like 7C, 0.1C nights, 137.2mm across over 10 days and 69 percent humidity.
Crater Lake-forum threads on September weather describe this as genuinely one of the strongest months for dry, comfortable conditions, daytime readings typically in the high sixties Fahrenheit though posters note the range can run from the forties to the eighties. Regulars call nighttime lows regularly dropping to around forty Fahrenheit, some nights genuinely dropping toward freezing even in a favorable stretch. Posters describe September as capable of turning beautiful, often called the most scenic month, though conditions can shift by mid-month with most facilities winding down by early October. Regulars recommend late September as generally fine, though posters flag a real caution, one visitor describing getting caught in an unexpected system during a past September's second week. Posters recommend a current forecast rather than assuming based on the calendar. The record: 17.4C days feeling like 15C, 4.7C nights, a notably high 2.3cm of fresh accumulation and 58 percent humidity.
