Weather in Rota

Find out the current weather conditions in Rota. In this section, you will find the latest data, detailed forecasts, and useful charts.

The climate in Rota, located in the Northern Mariana Islands, is characterized as tropical. Temperatures here remain remarkably stable throughout the year, with average values fluctuating between 26.5°C and 27.7°C. This means that travellers can expect warm weather regardless of the time of their visit, with minimum night temperatures rarely dropping below 25°C and daytime highs reaching a comfortable 28-29°C.

Despite the consistency of temperatures, two main seasons are clearly distinguishable in Rota, defined by the amount of rainfall. The drier season usually falls between January and May. During these months, precipitation is minimal (2-3 mm), and the number of rainy days varies from 14 to 20. Starting in June, rainfall gradually increases, ushering in the rainy season, which peaks from July to October. During this period, monthly rainfall can reach 13 mm, and the number of rainy days rises to 28-30, which is typical for tropical regions.

Therefore, when planning a trip to Rota, it is worth considering these seasonal features. If you prefer drier weather, the first half of the year would be the optimal choice. In the second half of the year, you should be prepared for more frequent, though often short-lived, tropical downpours, which contribute to the lush blooming of local vegetation.

The climate of Rota spoils travellers with practically unchanging warmth all year round. Average monthly temperatures here fluctuate within a very narrow range: from 26.5°C in February, which can be considered the "coolest" month, to 27.7°C in June, which is the hottest. This means that the concepts of a "cold" or "hot" season are quite relative here. Minimum night temperatures throughout the year usually hold at marks from 25.8°C to 26.7°C, and maximum daytime figures reach 27.2°C - 28.6°C. Such stability guarantees comfortable conditions for a holiday at any time.

Speaking of seasonal sensations, the months from May to November, when average temperatures reach their peak (from 27.3°C to 27.7°C), can be characterized as consistently hot. Daytime heat during this period often reaches 28.3°C - 28.6°C, and this time coincides with an increase in precipitation, which can add a feeling of humidity. The period from December to April is perceived as slightly less sultry, but still very warm, with average temperatures around 26.5°C - 27.3°C. During the day, the air warms up to 27.2°C - 28.1°C. An important feature of Rota's climate is the minimal diurnal temperature variation: the difference between day and night figures ranges from 1.4°C to 2.3°C, ensuring warm weather around the clock.

In Rota, as on many tropical islands, the pattern of precipitation is clearly divided into two main periods that determine humidity and the number of rainy days during the year. Snow, of course, does not fall here, and all precipitation comes in the form of rains of varying intensity and duration.

The driest period in Rota is observed from January to May. At this time, the amount of precipitation is minimal. The driest months are considered to be February and March, when only about 2 mm of precipitation falls, and the number of rainy days drops to 14-16 per month. In January, April, and May, rainfall is also low – about 3 mm, with rainy days numbering from 17 to 20. Rains during this period are usually short-lived and do not cause particular inconvenience.

From June, a gradual increase in rainfall begins, marking the transition to the rainy season, which reaches its peak from July to October. The greatest amount of precipitation falls in September and October – 13 mm in each. August stands out with the maximum number of rainy days – on average 30 days per month, with 12 mm of precipitation falling. July and October are also very wet, with 9-13 mm of rainfall and 28-29 rainy days. Rains during this period can be more intense and prolonged, which is characteristic of tropical downpours; however, they are often followed by sunny weather. November (5 mm of precipitation, 25 rainy days) and December (3 mm, 22 rainy days) are transitional months when the intensity of rains decreases.

When planning a trip to Rota, remember that warm tropical weather reigns here all year round. The basis of your wardrobe should be light, breathable clothing made from natural fabrics, such as cotton T-shirts, shorts, sundresses, and linen shirts. Do not forget swimwear, as the average air temperature consistently stays around 26-28°C. Important accessories will be high SPF sunscreen, headwear (a hat or cap), and sunglasses to protect against the bright tropical sun, which is active here at any time of the year.

Although the temperature in Rota remains comfortably warm throughout the year, seasonal changes in rainfall should be considered. If your trip falls during the period from June to October, when the number of rainy days increases significantly (up to 28-30 days a month with peak rainfall in August-October up to 13 mm), be sure to take a light raincoat or a compact umbrella. In the drier season, from January to May, when only 2-3 mm of precipitation falls, these items may be less critical, but a light jacket in case of a sudden downpour will still be useful. Regardless of the season, comfortable walking shoes, such as sandals or light trainers, will be indispensable.

Given the consistently high temperatures and the absence of significant fluctuations, the principle of layering clothing for Rota concerns protection from the sun or a light evening breeze by the water rather than keeping warm. A light long-sleeved shirt may come in handy both for UV protection during the day and for comfort in the evening. Also, considering the tropical climate and humidity, especially in the rainy season, insect repellent will not be superfluous. In general, your suitcase for Rota should be filled with items for hot weather, with an emphasis on protection from the sun and potential rain.
