レッドウッド国立公園 10月の天気

Redwood-forum threads on mid-October weather describe a genuinely favorable stretch, the heaviest winter rains still weeks away and frosts still rare, though posters are consistent morning fog and drizzle are a regular fixture that usually clears by mid-morning. A typical day is described as cool and misty at dawn under the canopy, then noticeably warmer once out in an open grove or coastal clearing, before cooling again as the sun drops. By month's end conditions turn a touch cooler and greyer, so posters recommend early-to-mid October over the final week for the best odds of a dry hiking day. Regulars call layers essential regardless of the exact date, since temperature under the redwood canopy can run several degrees cooler than in open, sunlit sections of the same trail. The record: 17.4C days feeling like 16C, 9.9C nights, 107mm across 7.2 days, a 12.4C sea and 77 percent humidity.

Redwood-forum threads on a February visit describe windy rain storms as genuinely possible, posters naming sunny days as equally realistic within the same week. Regulars call temperatures genuinely mild, several posters naming the low fifties Fahrenheit as standard alongside a real chance of rain on any given day. Posters call rainfall genuinely variable by location, several regulars naming Crescent City's sixty-five to seventy inches of winter rain as considerably more than Eureka's roughly forty-five. Regulars call snow genuinely rare here, several threads naming it light and brief whenever it does happen. Posters recommend real waterproof layers regardless of which part of the park you visit, several regulars calling this standard given how much rainfall varies even within a short drive. The record: 10.8C days, 4.5C nights, an extraordinarily high 215.7mm across 13 days and 81 percent humidity.

Redwood National Park-forum threads on a March trip from San Francisco describe conditions as genuinely unsettled this time of year, posters calling fog and a real chance of wind along the coast standard for the month. Regulars call real mud likely on most trails regardless of route chosen, a higher-clearance vehicle recommended for anyone planning to explore beyond the main paved roads. Posters recommend pushing as far north as Crescent City rather than stopping at the Avenue of the Giants, several regulars calling the northern sections genuinely the most scenic part of the park. Regulars call Trinidad a solid base for anyone wanting a coastal town rather than staying directly in the park. Posters recommend real waterproof layers regardless of how the morning looks, coastal conditions here shifting fast and often. The record: 11.4C days feeling like 10C, 4.8C nights, an extraordinarily high 246.8mm across over 16 days and 79 percent humidity.

Redwood-forum threads on a November visit describe the park as staying open year-round, posters calling real fog and rain the standing conditions this time of year. Regulars call daytime highs typically mid-fifties Fahrenheit with nights dropping into the low forties, considerably milder than the interior despite the coastal damp. Regulars describe Crescent City as seeing rain across roughly thirteen days in a typical November, several inches of real accumulation over the month. Posters call usable daylight genuinely limited this late in the year, the sun's low angle leaving only a few hours of good light on a clear day. Regulars call the fog curling among the ancient trees a genuinely unforgettable sight for anyone willing to embrace the dampness. Posters recommend real waterproof layers regardless of forecast, crowds here a fraction of the summer peak. The record: 13.5C days feeling like 11C, 7C nights, an extraordinarily high 215.3mm across nearly 13 days and 81 percent humidity.

Redwood-forum threads on planning an August trip are consistent the coast itself stays genuinely cool even at the height of summer, early mornings on the beach capable of feeling raw once fog and wind combine regardless of the calendar. Posters describe daytime highs near the ocean as staying modest, a real contrast to how warm inland spots just a few miles away can run the same afternoon. Regulars recommend real layers, a waterproof shell plus a lightly insulated jacket covering most conditions a visitor is likely to hit across a single day here. Posters call the marine layer a defining feature of summer specifically, often burning off by afternoon inland while the immediate coast stays shrouded longer. Regulars recommend checking which grove is coastal versus inland before dressing for the day. Posters call the ancient trees worth the trip regardless of a gray start. The record: 21.5C days feeling like 20C, 13.3C nights, a low 74 percent humidity and 12.6 hours of sun.
