9月のワタルコについての旅行者の声
ワタルコのほかの月
Regulars are specific the landscape stays visibly green here from the rainy season just ending, humidity itself running a touch higher than December even as this counts as many locals' pick for the nicest month of the year. Our row backs that hot, genuinely wet read, 31.1C reading as a scorching 37C, over 21.1C nights feeling 24C, with a substantial 86.3mm of rain across 15 days and humidity at 83 percent. Regulars are consistent the ocean itself runs calmer by this point with hurricane season now over, warm, comfortable days and evenings the common report despite the real remaining rain. Fewer tourists than peak season remains a genuine practical upside. The sea sits at a bath-warm 29.4C. The record: 10.3 hours of sun, an 8.5 kph wind and AQI 25.
April sits squarely in the dry season here, and regulars are unambiguous: hot, humid, virtually no rain, hotter than March by most accounts. Our row backs that at 19.5mm across 5.3 days, with 32.5C reading as a real 37C at 69 percent humidity. The one thing worth timing around is not weather but the calendar - the town fills for Easter, and once Easter Sunday passes the vacationing crowd almost disappears as Mexican visitors head back to work, leaving a quieter beach that only gets hotter from there. The sea stays warm and inviting throughout at 28.4C, good for fishing as well as swimming. Nights hold 21.8C. The record: 11.4 hours of sun, a 14.4 kph wind and AQI 45.
Regulars call January and February about as close to perfect as this coast gets, and the reason they give for January specifically is what it lacks. It does not rain - the wet season holds off until May - and wind is not the problem here that it is on the Caribbean side in the same weeks, which is the common reason people end up comparing the two coasts at all. Locals asked for the best month say January: the fishing is at its best and the whales are about. By mid-March the humidity climbs and the heat turns oppressive for northern visitors, so this is the cool end of the good run. Our row gives 30.9C days against 19.9C nights, an eleven-degree swing that makes the evenings genuinely cool. The record: 27.9mm across 5.1 days, 10.5 hours of sun, a 10.6 kph wind and a 27.5C sea.
Regulars describe mid to late December as all but guaranteed dry: low 90s Fahrenheit by day, low 70s in the evening, usually a breeze and hardly ever rain. Our row matches closely at 30.8C over 20.1C with 19.4mm across 4.4 precipitation days. The breeze is gentler than the reputation, 9.1 kph, which is part of why the humidity tells: 78 percent turns that 30.8C into a felt 36C. Their booking advice is about the calendar rather than the weather - the month gets busier as it goes and Christmas into New Year is the peak, so early to mid December buys the same conditions at lower prices and with fewer people on the bays. The record: 10.3 hours of sun, a 28.2C sea and AQI 25, among the cleanest air here.
