9月のグアナフアト州についての旅行者の声
グアナフアト州のほかの月
Regulars are specific this month marks the transition from the cooler, mid-November-to-mid-March dry season into the peak dry season that runs mid-March through mid-May, one visitor specifically noting the first week already starting to feel warm. Our row backs that hot, genuinely dry read, 27.5C reading as a hot 25C, over 10.1C nights feeling 8C, with rain essentially absent, 9.3mm across under 2 days, and humidity down to just 36 percent. Regulars are consistent low humidity keeps the real heat of April and May bearable when it arrives, this month still cooler and gentler than what follows. Nights in the mountain setting stay genuinely cool even as afternoons warm up fast. The record: 11.2 hours of sun, an 18.1 kph wind and AQI 46.
Regulars call this among the coldest stretches of the year here, with days that stay pleasant but nights and early mornings that turn genuinely cold - cold enough that a layer beyond a light jacket is standard advice, since most colonial-era buildings have little to no indoor heating. Our row backs the swing, 22.4C over a real 6C-feeling low, with rain nearly absent at 7.8mm across 2 days and humidity down to 54 percent, the dry highland winter regulars describe. The advice that follows from the lack of heating is practical rather than dramatic - pack a heavier sweater or fleece for the hours after sundown and before mid-morning, and expect daytime plans in the sun to feel entirely different from the same hour indoors. The record: 9.6 hours of sun, a 14.6 kph wind and AQI 38.
Regulars describe January as dry with bright t-shirt days and cold nights, and the practical advice that follows is about the building rather than the weather: check the place has heating, a fireplace or plenty of quilts, because many do not. Our row is why. Days reach 22.6C but nights fall to 6.9C and feel like 4C - a swing of nearly sixteen degrees inside one day, at 47 percent humidity. Rain is absent at 4.3mm across 1.3 days. They add that January is low season here, so a quieter town comes with the cold mornings. A windbreaker is worth carrying for the higher ground above the centre. The record: 9.7 hours of sun, a 16.6 kph wind and AQI 35.
October in Guanajuato is warm days and chilly mornings - regulars say the 70s and even 80s Fahrenheit by afternoon with lows in the 50s or sometimes the upper 40s, which our row's 24.6C over 12.2C matches almost exactly. The rains run mid-June to mid-September, so by now they are finishing: 45.7mm across 6.6 precipitation days. The thing to plan around is the Cervantino, which fills the whole of October with hundreds of events across four weeks. Regulars warn that the weekends are when it bites - streets closed, not enough taxis, and getting anywhere takes far longer than the map suggests. Weekdays are the same festival with room to move. The record: humidity 66 percent, 10.2 hours of sun, a 16 kph wind and AQI 36.

Rainy season
6月15日〜9月30日モンスーンRain arrives as short heavy afternoon storms rather than all-day weather, and the hills around the city turn green for the only months of the year. The tunnels under the centre flood briefly in the worst of it.

Independence days
9月13日〜17日国民の祝日混雑休業The independence war effectively started here at the Alhóndiga, so the middle of September carries more weight in Guanajuato than almost anywhere: the grito on the night of the 15th, then a full military and student parade. 出典 ↗
