During this period, rainfall is minimal – from 0 to 1 mm per month from December to April, and the number of rainy days is low, totaling just 1-4 days per month. From May to October comes the wet season, or monsoon season. It is characterized by a significant increase in the number of rainy days: for example, in June, July, and August, it rains almost daily (28-30 days per month). It is important to note that although the provided data indicates a relatively small amount of rainfall in peak monsoon months (16-19 mm), this may not fully reflect the typical intensity of tropical downpours characteristic of the region during this period. High humidity and frequent, sometimes heavy rains should be expected.

Despite seasonal changes in rainfall, the temperature regime in Cox's Bazar remains relatively stable, with high temperatures throughout the year. The hottest months are March, April, and May, when the average maximum temperature can exceed 30-32°C. The wet season is also characterized by high humidity, which is typical for a tropical monsoon climate, and this, combined with frequent rains, creates the unique atmosphere of this period.

Temperature fluctuations between day and night are most noticeable in the drier and cooler months, such as January and February, when the difference between maximum and minimum temperatures can be 8-9°C. During the peak of the hot and wet season, especially from June to August, diurnal temperature variations are less pronounced, amounting to only 3-4°C, which is associated with the high humidity and cloud cover characteristic of the monsoon period.

In Cox's Bazar, there is a clear division of the year into two main seasons regarding rainfall: a distinct wet season and a prolonged dry period. This seasonality is largely determined by the influence of monsoons characteristic of Bangladesh.

The dry season in Cox's Bazar usually lasts from December to March. During these months, precipitation is extremely rare or practically non-existent. According to the provided data, January, February, and March are the driest, with zero rainfall and only 1-2 rainy days in each. December is also characterized as a very dry month with similar figures. November and April can be considered transitional months, when rainfall is minimal (about 1 mm), and the number of wet days begins to increase or decrease.

The wet season covers the period from May to October, with its peak falling on the months from June to September. At this time, the amount of precipitation and the number of rainy days increase significantly. July stands out as the month with the highest recorded rainfall (19 mm). August is the month with the maximum number of rainy days — a full 30, meaning it rains almost daily. In June (17 mm of rainfall) and September (11 mm of rainfall), a high frequency of rains is also observed, with approximately 28 rainy days in each. May, with 4 mm of rainfall and 16 wet days, and October, with 6 mm of rainfall and also 16 wet days, serve as a sort of beginning and end to the main rainy season.

Precipitation in Cox's Bazar falls exclusively in the form of rain; snow is uncharacteristic for this region, which is due to consistently high temperatures throughout the year. During the monsoon period, especially from June to September, rains occur very frequently, covering most days. Although the indicated average monthly rainfall volumes (for example, 19 mm in July) may seem moderate, the high frequency of rainy days indicates constant and significant air humidity during this period.

When planning a trip to Cox's Bazar, it is important to consider its tropical monsoon climate, which is characterized by warm weather year-round and a distinct rainy season. In general, you will need light, breathable clothing made from natural fabrics such as cotton or linen. Do not forget sunscreen with high SPF, sunglasses, and a hat for sun protection, especially considering that Cox's Bazar is famous for its extensive beach. Comfortable footwear, such as sandals or light sneakers, is mandatory for walking.

In the evenings, especially from December to February, when the minimum temperature can drop to 16-18°C, a light sweater or cardigan may come in handy. Although rains are rare, a small compact umbrella may be useful, especially closer to April, when the number of rainy days increases slightly.

During this time, a significant amount of precipitation falls, especially from June to August, when the number of rainy days reaches 28-30 per month.

During this period, it is extremely important to bring a waterproof jacket or raincoat, as well as a reliable umbrella. Clothing should be quick-drying. It might be worth taking an extra pair of shoes, as one pair may get wet. Also, consider waterproof cases for electronics and documents. The principle of layering is less relevant here due to the constant heat, but quick-drying items and rain protection are your main priority.
