ヤンゴンの月別の天気

Yangon's forum calls December through January the cool season — warm days around 29°C dropping to 20°C at night, low humidity, and minimal rain. Regulars rate it among the best times to visit Myanmar generally, with the added bonus of cheaper hotels and fewer crowds at the major sights.

February closes the cool dry season that runs from November, and it is the month regulars name for Yangon - dry, low humidity, no warm clothing needed at all. What they qualify is the middle of the afternoon: it gets properly hot between about two and five, and that is the part of the day to spend indoors or under something. Their range of 27 to 32C by day and 18 to 20C at night sits under our row's 34.7C and 18.9C, which reads as 37C at the peak. Rain is essentially absent, 4.5mm across 0.6 days. The record: humidity 61 percent, 10.6 hours of sun and AQI 93.

Regulars describe real days this month already tipping over 40C, hot enough that one traveler's own account described needing to retreat to air-conditioned cafes and rest rather than keep sightseeing through the afternoon. Our row backs that hot, genuinely dry read, 36.9C reading as a brutal 40C, over 22C nights, with rain essentially absent, 5.4mm across just 1 day, and humidity down to 60 percent. Regulars are consistent this counts as noticeably less humid than nearby Singapore despite the intense heat, and that the real peak of the hot season is still just ahead in April. Slowing down midday, staying hydrated and planning temple visits for early morning or evening are the standard local advice. The record: 11 hours of sun, a 12.2 kph wind and AQI 97.

Myanmar-forum threads asking if May is simply too hot confirm the central plains, Yangon included, run extremely hot through the early part of the month, temperatures near 100 Fahrenheit some days, with the most intense heat concentrated at the start of May and easing somewhat by the end. Rain does arrive as the wet season gets underway, but posters describe it as sudden, hard bursts lasting only an hour or two rather than settling in for the day. May sits firmly in the low season here, largely because of the heat, which translates into noticeably thinner crowds and posters calling it a genuinely good value month for anyone who can handle the temperatures. Regulars are candid this month is a hard pass for visitors who struggle with serious heat, better suited to those touring temples early morning or late afternoon. The record: a scorching 35.6C by day feeling like a punishing 41C, 25.1C nights, a notably high 241mm across 19.9 days, 75 percent humidity and 9.4 hours of sun.

Forum posters are upfront that July sits in the peak of monsoon season with genuinely heavy rain most days, but they're equally clear it's still visitable: rain isn't cold, doesn't fall all day, and clear-sky stretches are common between downpours, with the whole country turning vividly green and temperatures actually a bit cooler than the pre-monsoon heat. Posters recommend leaning toward central Myanmar - Bagan, Mandalay, Amarapura, Kalaw, Pyin Oo Lwin - since the south and west coasts see the worst flooding risk this time of year. The clear upside for budget-conscious travelers: July counts as low season, meaning noticeably lower prices across the board.

Yangon-forum threads on November weather confirm the wet season has essentially wound down by this point, most days running clear and reliably fine rather than washed out. Posters describe daytime heat as still real, comfortably warm rather than the punishing extremes of the pre-monsoon months, with nights by late November cooling enough to actually feel pleasant after dark. Regulars are consistent Yangon itself stays milder than the drier-zone towns further north like Mandalay and Bagan, which run noticeably hotter on the same November dates. The standing local rhythm - morning and early-evening sightseeing bracketing a restful, shaded midday - applies year-round but is especially comfortable to follow this month. Regulars call November the genuine start of the region's best travel stretch, running through February. The record: 33.6C days feeling like a punishing 38C, 22.5C nights, 80 percent humidity and 9.9 hours of sun.

December sits in the cool, dry stretch that runs November to February, and the Yangon forum's regulars are quick to qualify the word cool: the city stays warm and balmy - they put it at about 30C by day and 21C at night - and it is Bagan and Mandalay that actually get chilly after dark, not here. What December buys you is the absence of rain and the clearest skies of the year, which is also why it is peak season and the most expensive time to come. Christmas is widely marked despite the country being Buddhist, with decorations and parties in the tourist hotels. The record: 33C days that feel like 36C, 19.8C nights, 0.8 precipitation days, 10.2 hours of sun, AQI 68.
