If you’re planning a trip to central Myanmar, you’ll want to know what to expect from Mandalay’s weather. Summer in Mandalay gets seriously hot—daytime highs often hit 37°C (99°F), and even at night, it barely cools down, sticking close to 27°C (81°F). Humidity climbs, clouds hang around, and rain showers come and go but get less frequent as the months wear on.
June and July bring long daylight hours, then things start to shift a bit as August winds down. Rain falls most often at the start of summer, then drops off. Winds usually come up from the south, so you get a mild, steady breeze cutting through the thick air.
When you know these patterns, it’s easier to pack and plan for the heat or those sudden downpours. Exploring Mandalay’s historic sites or just wandering outdoors feels different when you know what kind of summer you’re stepping into.
Summer Climate Overview in Mandalay
Mandalay’s summer hits with high temperatures, sticky humidity, and lots of clouds. Rain shows up early in the season, then backs off as summer moves ahead. Daylight hours shrink just a bit by the end of summer.
Typical Summer Temperature Range
You’ll see daily highs near 99°F (37°C) through most of the season. Temperatures hardly ever dip below 92°F (33°C) or shoot past 107°F (42°C). Nights? Still warm—lows hover around 81°F (27°C).
Late April usually brings the hottest weather, just before the monsoon season. In those weeks, afternoon temps can top 100°F (38°C). August cools off slightly, but it’s still hot, and nights don’t offer much relief.
For a quick look:
- Daytime highs: 92–107°F (33–42°C)
- Nighttime lows: 78–86°F (25–30°C)
- Hottest stretch: Late April to early June
If you’re out during midday, brace yourself for long stretches of heat.
Humidity and Dew Point Levels
Mandalay’s humidity ramps up fast in summer. Dew points often climb above 70°F (21°C), so the air feels muggy and heavy. Even in early summer, you’ll notice the stickiness, but by July and August, muggy days are almost guaranteed—over 95% of the time.
Nights don’t really cool off, either; the air stays thick and damp. Unlike cooler places, evenings just don’t bring much relief. High dew points also mean sweating doesn’t help you cool down as much.
On the worst days, it feels downright oppressive or even miserable. If you’re in Mandalay during summer, keep hydrated and try not to overdo it outside in the afternoon.
Seasonal Weather Patterns
Summer lines up with monsoon season in Mandalay. Clouds take over the sky—overcast or mostly cloudy more than 75% of the time. July stands out as the cloudiest, with overcast conditions peaking close to 90%.
June brings frequent rain, but by August, showers become less common. Average rainfall drops from about 0.9 inches per 31 days in early June to 0.5 inches by late August.
Daylight shifts, too. In June, you get about 13 hours and 29 minutes of daylight. By late August, that’s down to roughly 12 hours and 35 minutes. Sunrise creeps later and sunset comes earlier, but the change is pretty gradual.
Winds average 8–9 mph, usually blowing from the south. Early July can get breezy, with gusts over 12 mph. These winds, mixed with humidity, really define Mandalay’s summer feel.
Monthly Breakdown of Summer Weather
Monsoon season takes over Mandalay’s summer, bringing heavy rain, high humidity, and less sunshine. Temperatures stay warm, though not quite as blistering as spring. Rain, though, becomes a daily fact of life.
June Weather Snapshot
By June, Mandalay is deep into the rainy season. Expect average highs around 33.9°C (93°F) and lows near 25.9°C (78.6°F). The worst of the heat fades, but the humidity ramps up.
Rain jumps to about 105 mm (4.1 in), with showers often in the afternoon or evening. Streets can flood after heavy downpours, so it’s smart to keep your plans flexible or have indoor options.
Sunshine averages out to about 7 hours per day. You’ll catch some clear skies between showers. The air feels thick, but at least it’s not as brutally hot as pre-monsoon months.
July Weather Snapshot
July is usually the wettest month. Rainfall climbs to an average of 121 mm (4.7 in), and clouds stick around. Daytime temps range from 25.1°C (77°F) at night to 31.9°C (89°F) during the day.
Humidity stays high, often above 70%. This makes sightseeing a sweaty challenge, especially midday. Rural roads and city paths get muddy or slippery, so travel can be tricky.
Sunshine drops to its lowest, averaging just 6.9 hours per day. You’ll still get some breaks in the clouds, but expect mostly gray skies. The upside? It’s not as scorching as April, so that’s something.
August Weather Snapshot
August keeps the monsoon going strong. Rainfall peaks at about 170 mm (6.7 in), the highest for the year. Storms can be intense but usually don’t last long—afterward, it’s humid but a bit cooler.
Highs stay near 31.4°C (88.5°F), with lows around 24.7°C (76.5°F). The near-constant rain cools things off compared to earlier in the year, though it still feels sticky.
If you’re traveling, expect frequent showers. Light rain gear and waterproof shoes make getting around easier. Outdoor fun is limited, but the city’s greenery really pops during these rainy weeks.
Rainfall and Precipitation Trends
Mandalay’s climate swings between tropical wet and dry, so rainfall isn’t spread out evenly. Dry months kick off the year, then the monsoon brings heavy rains.
Average Rainfall by Month
Rain in Mandalay follows a pretty clear cycle. From November to April, rain is scarce, often less than 10 mm a month. February is usually driest, with just about 5 mm.
Once May hits, rainfall jumps. By June, monthly totals can top 150 mm, and they keep rising through the monsoon peak. September is the wettest month, with around 230–240 mm of rain.
Here’s a quick table:
| Month | Avg. Rainfall (mm) |
|---|---|
| Jan | ~7 mm |
| Feb | ~5 mm |
| Mar | ~10 mm |
| Apr | ~30 mm |
| May | ~130 mm |

| Jul | ~190 mm |
| Aug | ~210 mm |
| Sep | ~238 mm |
| Oct | ~120 mm |
| Nov | ~20 mm |
| Dec | ~8 mm |
You can really see how the rain piles up from May to October.
Number of Rainy Days
Rainy days change a lot with the seasons. From December to March, you might only get 0–2 days of rain each month. It feels pretty dry, even though temperatures stay warm.
By June, rainy days jump to about 10–12 days a month. July and August usually see 11–13 rainy days, and September averages around 12. Rain comes in short, heavy bursts rather than all-day drizzles.
October brings fewer wet days—about 7–8—and by November, things dry out again. You get long sunny stretches in the dry season and regular showers during monsoon.
Wettest Months Overview
Mandalay’s wettest stretch runs from July to September, with September as the peak. You can expect over 200 mm of rain in a single month. Temperatures stay hot, averaging around 33°C, so the humidity feels even heavier.
Rain usually comes in big downpours, not all-day drizzle. Storms often hit in the afternoon or evening, leaving the rest of the day dry or even sunny. That’s typical for tropical monsoon climates, so you can plan around it.
If you’re visiting, be ready for muddy streets, higher river levels, and the occasional flood in low spots. Still, you’ll get plenty of sunshine each month, balancing out the rain.
Sunshine and Daylight Hours
How much sunshine you get in Mandalay during summer depends on clouds and the length of the day. Even though the days are long, the wettest months bring less direct sunlight.
Average Daily Sunlight
June to August are the cloudiest months. Mandalay gets about 5 to 6 hours of direct sunlight per day during this time. July averages 5 hours 52 minutes, and August drops to around 5 hours 25 minutes.
Heavy cloud cover cuts down on sunshine, even if daylight lasts more than 12 hours. Only about 43–52% of daylight is actually sunny—the rest is spent under clouds or haze.
Compare that to the dry season, when over 80% of daylight is sunny, and you’ll notice the difference. If you’re planning outdoor stuff, expect shorter windows of sun and more overcast skies.
Length of Day During Summer
Day length shifts with the seasons, but summer days are some of the longest. June gives you about 13 hours 26 minutes of daylight. July isn’t far behind at 13 hours 19 minutes. By August, days shorten to about 12 hours 51 minutes.
The longest day is around 13 hours 20 minutes, while the shortest is about 10 hours 39 minutes. So in summer, you get about 2 hours and 40 minutes more daylight than in winter.
Even with lots of clouds, those long days give you plenty of time for sightseeing or travel. You may not always have bright sun, but there’s still lots of usable daylight.
Wind and Air Quality Conditions
In Mandalay’s summer, expect mostly light or moderate winds, and sometimes it just feels still. These conditions, mixed with heat and humidity, really affect how the city feels—and the air quality too.
Typical Summer Wind Speeds
Summer winds usually stay gentle, between 3 to 7 miles per hour (5–11 km/h). Strong breezes are rare, so there’s not much to cool you off.
Calm air is common, especially at night. Without much wind, the heat feels even more intense.
Summer winds often shift with the monsoon, bringing moisture up from the Bay of Bengal. Southerly and southwesterly winds help drive the seasonal rain in June, July, and August.
With weak winds, dust and smoke from city life can hang in the air. That’s why wind matters for both comfort and air quality if you’re spending time in Mandalay.
Air Quality During Summer
Air quality in Mandalay during summer really depends on the weather and what’s happening around town. High humidity and those frequent rain showers can knock down airborne dust, but when it’s dry and hot, particles just seem to hang in the air.
In the city, vehicle emissions, cooking smoke, and construction dust usually create most of the pollution. When winds die down, these pollutants tend to linger near ground level, so the air looks hazier than usual.
Rainy days in July and August usually clear things up and make the air feel fresher. On dry days in June or September, though, you might notice more fine dust, especially if you’re near busy roads.
If you’re sensitive to air quality, try to plan your outdoor time during or right after rainfall. The air feels cleaner and honestly, it’s just more pleasant.
Travel Tips for Visiting Mandalay in Summer
Mandalay’s summer hits with high heat, strong sun, and not much rain until the monsoon arrives. Timing and a little prep go a long way for a comfortable trip.
Best Times to Visit
Summer in Mandalay usually stretches from March to May. Temperatures often shoot up past 35°C (95°F), and April can feel like an oven. Humidity stays lower than during the rainy season, but the dry heat gets intense if you’re outside too long.
If you want to see temples, markets, or the Irrawaddy River, aim for early mornings or late afternoons. The midday sun feels brutal, especially anywhere without shade.
Public spots like Mandalay Hill or U Bein Bridge feel much nicer when the sun isn’t right overhead. You’ll also beat most of the crowds if you go early, which makes wandering around a lot easier.
Summer might not be the most comfortable season, but you can still enjoy your trip with a bit of planning. Drink plenty of water and take breaks so the heat doesn’t wear you out.
What to Pack for Summer Weather
Pack lightweight, breathable clothing like cotton shirts, linen pants, or long skirts. These fabrics help you stay cooler and give you modest coverage, which really matters if you plan to visit religious sites.
You’ll want a wide-brimmed hat, sunglasses, and high-SPF sunscreen because the sun can get intense. Bring a refillable water bottle too, since you might end up walking a lot around temples or markets, and it’s just too easy to get dehydrated.
Choose footwear that you can slip on and off easily. You’ll probably remove your shoes a lot at pagodas, so sandals with decent support make life a whole lot simpler.
Toss a small umbrella in your bag. Early summer doesn’t see much rain, but as late May rolls around, sudden showers might catch you off guard, and hey, an umbrella works for sun protection too.
