Cox's Bazar sits on the southeastern coast of Bangladesh, where 120 kilometers of unbroken sandy shoreline stretch along the Bay of Bengal, making it the longest natural beach on Earth. Beyond the surf and golden sand, you'll find a culturally layered destination shaped by Bengali, Rakhine, Chakma, and Marma communities, each contributing distinct traditions, food, and festivals. The local seafood scene alone is worth the trip: grilled prawns, rich coconut prawn curry in the Rakhine style, pungent shutki maach (dried fish fried with spices), and the Chakma specialty of bamboo chicken cooked over open flame.
Your best window for Cox's Bazar runs from late November through late February, when dry skies, comfortable temperatures, and calm seas make this stretch of coastline ideal for beach days, island hopping to Saint Martin's, and sunset drives along the 80-kilometer Marine Drive. Winter highs sit at 83°F (28.3°C) with lows dropping to a pleasant 62.8°F (17.1°C), and rain is nearly absent. December draws big domestic crowds, so if you prefer quieter beaches and easier hotel availability, aim for January or February. Budget travelers should also consider October and November as a shoulder alternative, when monsoon rains taper off and accommodation prices drop.
Spring in Coxs Bazar, Bangladesh
March kicks off the hot season in Cox's Bazar, and the heat builds steadily through May. Highs average 91.7°F (33.2°C) across these months, and humidity creeps upward as the monsoon approaches. If you visit during the Bengali New Year celebration of Pohela Boishakh in mid-April, you'll see streets come alive with colorful processions, traditional music, and festive food stalls. The indigenous Boishabi festival, celebrated by Chakma, Marma, and Tripura communities, falls in the same mid-April window and features traditional dance and rituals that offer a window into the region's diverse heritage.
The heat peaks in mid-April, when highs climb to 93.3°F (34.1°C) with lows around 78.4°F (25.8°C). That kind of intensity means mornings and late afternoons are your best bet for beach walks along Laboni or Kolatoli. Rain remains relatively light through March and most of April, with showers picking up only toward late May when the monsoon starts to announce itself. Air quality during spring sits in the Unhealthy for Sensitive Groups range, so travelers with respiratory concerns should factor that into their plans.
Spring is the second busiest season for domestic tourism, and April in particular draws large Bangladeshi crowds during holiday periods. Accommodation prices reflect the demand. Pack light, breathable clothing, a good hat, and high-SPF sunscreen, because the sun is relentless.
Summer in Coxs Bazar, Bangladesh
The monsoon arrives in full force from June through August, transforming the coast. Himchari's waterfall, a modest trickle in dry months, swells into a dramatic cascade worth the short drive south of town. The landscape turns a vivid green as rice paddies and hills soak up the rain. Highs average 88.3°F (31.3°C) with lows of 78.4°F (25.8°C), and the air feels heavy with humidity regularly exceeding 80%.
July is the wettest month, with rain on the majority of days. June sees wet afternoons roughly 59% of the time, and August isn't far behind. Flooding and road closures can disrupt travel, particularly along the Marine Drive route toward Teknaf and Saint Martin's Island. Boat services to Saint Martin's typically suspend during peak monsoon, so plan around that if island trips are a priority. Despite all this, summer is paradoxically the busiest tourism season, driven by Bangladeshi school holidays and Eid celebrations. Hotels fill quickly, and prices run higher than you'd expect for monsoon conditions.
Air quality actually improves during July, reaching its best levels of the year. If you do visit during monsoon, bring waterproof bags for electronics, quick-dry clothing, and sturdy sandals that can handle wet conditions.
Fall in Coxs Bazar, Bangladesh
September still feels like an extension of monsoon season, with showers expected roughly 46% of the time and the sea remaining rough. By October, things start shifting noticeably. Rainfall drops to around 25% of days, and by November it falls to just 4%, signaling the start of the dry season. Highs average 89.1°F (31.7°C) across fall, with lows settling at 75°F (23.9°C), still warm but less oppressive than the summer humidity.
Late November is where fall gets interesting. The beaches clean up after months of monsoon, the air dries out, and crowds haven't yet surged for the December holiday season. This is a strong window for exploring the Burmese Market, where vendors sell handwoven textiles, seashell crafts, and local dried fish. A half-day trip to Maheshkhali Island, just a 15-minute motorboat ride away, takes you to the hilltop Adinath Temple dedicated to Lord Shiva and a nearby Buddhist pagoda with sweeping views of the sea and mangrove forest. Air quality in October and November sits in the Unhealthy for Sensitive Groups range, so sensitive travelers should take that into account.
Tourism volume is relatively low through fall, making it easier to find accommodation at lower rates. This is the time to enjoy Inani Beach, about 25 kilometers south of town, where coral-studded shores and cleaner water draw swimmers and photographers, especially around sunset. Pack a light layer for cooler evenings in late November.
Winter in Coxs Bazar, Bangladesh
Winter is when Cox's Bazar is at its best for visitors. The sea calms down, humidity drops to its lowest levels, and the sky stays clear day after day. Highs of 83°F (28.3°C) feel genuinely comfortable, especially with the gentle coastal breeze, and lows of 62.8°F (17.1°C) make evenings on the beach pleasant rather than sweltering. Rain is nearly nonexistent: December sees precipitation just 2% of the time, and January drops to 1%.
This is the season for island hopping. Boat services to Saint Martin's Island, Bangladesh's only coral island, resume during winter, and the calm seas make the journey from Teknaf far more enjoyable. Back on the mainland, the 80-kilometer Marine Drive from Cox's Bazar to Teknaf is at its most scenic, with hills on one side and the open beach on the other. Traditional moon-shaped sampan boats dot the shoreline, and sunset drives along this route are among the most memorable experiences in Bangladesh. At Dulahazara Safari Park, about 50 kilometers north of town, you can spot Bengal tigers, elephants, and deer in a spacious natural habitat.
December draws big domestic holiday crowds, making it one of the busiest months alongside May and June. February, by contrast, is the quietest month of the year, ideal if you want long stretches of beach to yourself. Air quality during winter months sits in the Unhealthy for Sensitive Groups to Unhealthy range, with February being the worst month; travelers with breathing sensitivities should plan accordingly. Pack light layers for cool mornings, sunscreen for midday, and a light jacket for after dark.

Travel Tips & Safety for Coxs Bazar, Bangladesh
Cox's Bazar is served by an international airport with domestic flights from Dhaka on carriers like Biman Bangladesh Airlines, US-Bangla Airlines, and Novoair, making the trip far quicker than the 10 to 12 hour bus ride. Trains run from Dhaka to Cox's Bazar in roughly 9 hours and are worth booking in advance for a comfortable seat. Within the city, auto-rickshaws (CNGs) and rented scooters are the most practical ways to get around, and hired jeeps will take you to Inani Beach or Himchari.
Stick to bottled water, and check food prices before ordering at beachside restaurants, as some establishments quote different rates to tourists. The sun is intense year-round, so carry high-SPF sunscreen and stay hydrated. Monsoon season from June through September brings the risk of flooding and road closures on low-lying routes, so monitor local conditions if you're traveling during those months.
The Tourist Police unit operates in Cox's Bazar's main beach areas and can assist with directions or safety concerns. Keep valuables secure and be aware of your surroundings in crowded markets like Burmese Market. Dress modestly when visiting religious sites, including the temples on Maheshkhali Island and the Buddhist monasteries in Ramu.
