Bangladesh in May: Weather, Crowds & What to Expect

Northern Plains (Rangpur, Rajshahi, Dinajpur)

May is oppressive: heat and humidity combine to make mid‑afternoon feel stifling with highs around 35-38°C before the monsoon breaks. The Nor’westers intensify, bringing short, violent rains that cool the air but can turn rural tracks to mud. Travel by local roads becomes slower; keep bottled water, a hat and avoid midday cycling when the sun is strongest.

Central & Greater Dhaka Floodplain (Dhaka, Mymensingh, Gazipur)

May is the final push before the monsoon; humidity is high and the heat can be oppressive, especially in traffic-choked Dhaka where temperatures can feel above 35°C. Nor’westers are still frequent and may cause scattered damage to trees and power lines. Travel inside the city is slower - avoid mid-day road travel, choose early starts, and keep sunscreen and cooling wipes handy.

Eastern Hills & Sylhet Region (Sylhet, Srimangal, Bandarban, Chittagong Hill Tracts)

May is humid and storm-prone; the pre-monsoon convective storms bring heavy local rain that drenches tracks and can trigger small landslides on steep hill roads. Tea-picking continues despite showers, and the waterfalls around Bandarban surge - great for photography but slippery underfoot. If you plan hikes, choose certified guides and be prepared for muddy trails and wet gear.

Southern Coast & Sundarbans (Khulna, Sundarbans, Kuakata, Patuakhali)

May heats up before the monsoon, and the coastline becomes humid and oppressive during the afternoons; sea breezes offer some relief but storms are frequent. Fishermen adjust schedules for rough seas while tidal surges can occasionally flood low-lying embankments near the Sundarbans. Travel plans that include small boat trips should factor in cancellations and bring waterproofs and emergency contact details.

Cox’s Bazar & St. Martin’s Island (Southeast coast, Teknaf, Himchari)

May combines strong heat with mounting humidity; sea conditions can be choppy and small fishing boats may pause operations during thunderstorms. This pre-monsoon period has occasional cyclonic disturbances that can disrupt schedules and cause rough launches to the island. Travelers should be cautious about day-trips and keep flexible plans and backup accommodation in Teknaf or Cox’s Bazar.
