The calendar decides what this trip costs and feels like
Cox’s Bazar is a domestic holiday destination first, and the domestic calendar governs everything: prices, crowds, whether boats run and whether you can get a bus seat. Get the timing right and you have an empty beach at monsoon rates; get it wrong and you are paying double to share the sand with a hundred thousand people.
Three forces drive it. The dry-season peak from November to February brings the best weather and the highest prices. The two Eids and the national holidays produce enormous short surges regardless of season. And the monsoon from June to September empties the coast, drops rates to their floor, and makes the sea genuinely dangerous while making the hills spectacular.
Layered on top are the local festivals, which are worth planning around rather than avoiding: Shiva Chaturdashi at the Adinath temple on Moheshkhali in February or March, the Buddhist festival calendar at Ramu, and Pohela Boishakh, the Bengali new year, in mid-April.
Season by season, with prices attached
November to February is the season. Dry, 22 to 30°C, flat sea, clear water, the St Martin’s ferry running, and rates 30 to 50% above the annual floor. December and January are the busiest weeks of the year outside Eid, and Friday and Saturday nights carry a premium throughout — book weeks ahead and arrive midweek if you can.
March to May is hot and humid, into the mid-thirties, with the Himchari waterfall drying to stone and midday activity limited to shade and water. Rooms fall 20 to 30% and the strip is noticeably calmer. June to September is the monsoon: long warm downpours, a dangerous swell, cancelled boats, and the lowest rates of the year — along with the greenest hills and the only period when the waterfall actually falls.
October is the quiet bargain and the month we would choose: rain easing, air washed clean, sea settling, crowds not yet returned, and prices still near their monsoon floor for the first half of the month.
Eid, holidays and the domestic surge
Both Eid al-Fitr and Eid al-Adha bring the largest crowds of the year to this coast, as do Durga Puja, Victory Day and the other national holidays. Room rates double, the beach at Laboni fills wall to wall, buses and flights sell out days in advance, and restaurants run out of fish by nine in the evening. It is one of the great sights of Bangladeshi public life and genuinely worth experiencing once.
If you want a quiet trip, check the dates before you book anything at all — the Eid dates move each year with the lunar calendar, and the difference between the week before and the week of is the difference between $30 and $75 for the same room. If you want the spectacle, book six to eight weeks out and accept that you will be sharing everything.
Ramadan changes the rhythm rather than the crowd: kitchens open after sunset, daytime eating in public is best kept discreet, the strip is subdued by day and busy late, and iftar spreads appear everywhere at dusk. It is an interesting and entirely manageable time to visit.
Local festivals worth timing a trip around
Shiva Chaturdashi, in February or March, fills the Adinath temple hill on Moheshkhali with pilgrims from across the country; boats run constantly and the stepped path up through the stalls is at its liveliest. It is the single best cultural event accessible from the beach, and it needs nothing more than an early boat and modest clothing.
At Ramu, the Rakhine Buddhist calendar produces several observances through the year, with the prayer halls at their most active and the monastic community visibly at work. The Rakhine water festival around mid-April, tied to the new year, is the most colourful of them. Ask locally for dates; they are not reliably published.
Pohela Boishakh, the Bengali new year on 14 April, brings music, processions and new clothes to the town and the beach, and the fishing communities mark their own seasonal rituals around the start and end of the ban periods. None of this is staged for tourists, which is precisely why it is worth seeing.
The year, month by month
Prices are relative to the annual floor in July and August.
The best weather of the year and the first big rush. St Martin’s sailings resume, the sea flattens, and December weekends sell out weeks ahead.
Cool mornings, warm afternoons, the clearest water. Shiva Chaturdashi on Moheshkhali falls in this window or just after.
Mid-thirties and humid, waterfall dry, beaches fine before ten and after four. Pohela Boishakh on 14 April; noticeably cheaper rooms.
Heavy warm rain, dangerous swell, cancelled boats, greenest hills and a working waterfall. The cheapest rooms of the year and an empty coast.
Rain easing, air clean, sea settling, crowds absent. The best value week of the year is usually the first or second in October.
The largest domestic surge of the year: doubled rates, sold-out buses, wall-to-wall sand. Extraordinary to witness, expensive to book late.

Timing questions
When is the best time to visit Cox’s Bazar?+
November to February for weather — dry, 22 to 30°C and calm water — but at the highest prices and biggest crowds. October is the best compromise: settled sea, clean air, few people and rates still near their monsoon floor.
What is it like during Eid?+
Extraordinarily busy. Room rates roughly double, buses and flights sell out days ahead, and the beach at Laboni fills wall to wall with domestic holidaymakers. Worth seeing once; worth avoiding if you want quiet.
Is the monsoon a bad time to come?+
For swimming, yes — the swell is dangerous and boats are cancelled. For everything else it has real appeal: the cheapest rooms of the year, an empty coast, green hills and the Himchari waterfall actually flowing.
Are there festivals worth planning around?+
Shiva Chaturdashi at the Adinath temple on Moheshkhali (February or March), the Rakhine Buddhist observances and water festival at Ramu around mid-April, and Pohela Boishakh on 14 April. None are staged for tourists.
When does the St Martin’s ferry run?+
In the dry season only, broadly November to March, subject to sea conditions and to regulations that have changed repeatedly in recent years, including visitor caps and overnight restrictions. Confirm locally within days of travelling.
