Most packing guides for Bangladesh hedge across the whole year and end up useless for any particular trip. The actual decision point is binary: are you arriving in the monsoon, roughly June to September, or in the dry winter window of November to February? Almost everything else follows from that.
What both trips need
- Loose, modest clothing — shoulders and knees covered, in cotton or linen rather than synthetics. This is the single constant across both seasons.
- A scarf — required for mosques and many shrines, and useful against sun, dust and unwanted attention the rest of the time.
- Cash in small notes — cards work in city hotels and little else. Visa on arrival is cash-only in US dollars or euros.
- A universal adapter — Bangladesh runs 220V, most commonly on round-pin sockets.
- Water purification — tablets, a filter bottle, or the budget for bottled water every day. Do not drink from the tap.
- A basic medical kit — rehydration salts above all, plus anything you take regularly, since specific brands are hard to find outside Dhaka.
One structural note before the seasonal split: pack light and plan to buy clothes here. A locally made salwar kameez or a cotton panjabi costs very little, suits the climate far better than anything you brought, and reads as respectful rather than costume. Leaving space in the bag is a strategy, not an oversight.
Monsoon: June to September
The defining fact of monsoon packing is that you will not stay dry, so the goal shifts from staying dry to drying quickly. Heavy rain arrives in bursts, humidity sits high between them, and anything cotton that gets soaked in the morning will still be damp at bedtime.
Quick-dry synthetics over cotton. This is the one place where the modest-cotton advice bends. Loose, opaque, fast-drying fabric beats cotton that stays wet for a day.
Sandals you can walk in wet, not waterproof boots. Streets flood. Boots fill up, then hold the water in. Sturdy sport sandals or plastic shoes that you can rinse and wear again dominate here, and they are what most locals wear in the rain.
Dry bags for anything electronic. Not a rain cover — an actual sealed dry bag. Between the rain and the boat travel that defines this season, a phone and passport in a waterproof pouch is not excessive.
An umbrella, which beats a rain jacket. A waterproof shell in 90% humidity turns into a sauna. Everyone here uses umbrellas, and they are sold on every corner.
Strong insect repellent, with the mosquito season in mind. Standing water after the rains means mosquitoes, and dengue is a genuine seasonal concern in Dhaka rather than a theoretical one. Repellent with DEET, and long sleeves at dusk.
Monsoon is the wrong season for the beach and the right one for the landscape: the swamp forests near Sylhet are only properly flooded and navigable when the rains are at their heaviest, and the waterfalls only run then.
Dry season: November to February
The peak travel window, and a much simpler bag. Days are warm and clear, rain is minimal, and the sea is calm enough to swim in.
A warm layer, which surprises people. This is the item most visitors get wrong. December and January mornings in the north — Rangpur, Rajshahi, and up around Bogura — get genuinely cold, and cold fog regularly delays flights and ferries. In the hill tracts around Bandarban, nights are colder still. A fleece or light down layer is not optional if your trip goes north or up.
Sun protection over rain protection. Clear skies mean the sun is the hazard now. A brimmed hat, sunglasses, and high-factor sunscreen — the last is expensive and hard to find locally, so bring it.
Proper walking shoes rather than wet-weather sandals. Dry ground means you can finally use them, and the hill tracts and the Sundarbans boardwalks both justify them.
Swimwear you can actually use. Dry season is beach season at Cox's Bazar. Bear in mind that this is a conservative domestic beach: a rash guard and shorts will get you in the water with far less attention than a bikini.
A dust layer.The flip side of no rain is that Dhaka's air quality drops sharply in winter. A scarf over the face on a CNG ride does real work, and some visitors bring a proper mask.
The shoulder months
March to May is hot and building toward humid, with temperatures climbing well past comfortable and pre-monsoon storms arriving without much warning. October sits the other way: rains easing, the landscape still green, crowds not yet arrived. Pack it as a dry season trip with an umbrella added.
