Moroni, the capital of Comoros, features a tropical climate characterised by warm weather year-round. Temperature fluctuations throughout the year are insignificant: average monthly temperatures range from 22.4°C in August to 25.8°C in March. This ensures comfortable conditions for visiting at practically any time of the year, provided you prefer warmth.

Two main seasons can be distinguished in Moroni, differing in rainfall amount and the number of rainy days. The wetter season usually lasts from December to April, when the number of days with precipitation reaches 26 per month, although total rainfall remains relatively low (maximum 11 mm in January). From May to November comes a drier period, especially from July to October, when the number of rainy days drops to 12-14 per month, and rainfall volume is minimal (just 1 mm).

Thus, when planning a trip to Moroni, one can expect consistently warm weather. The main difference between the seasons lies in the frequency of precipitation, which, judging by the data, most often comes in the form of light or short-lived rains rather than prolonged downpours. Even in the so-called "dry" season, the chance of encountering rainy days remains, though it is significantly lower.

The annual temperature regime in Moroni is distinguished by pleasant stability and warmth, typical of a tropical climate. Average monthly air temperatures in the city fluctuate within a rather narrow range: from 22.4°C in August, which is the "coolest" month, to 25.8°C in March – the peak of the warmest period. Thus, the annual amplitude of average temperatures is only about 3.4°C, ensuring comfortable conditions for visiting all year round for those who love the heat.

The so-called "summer" or hotter and wetter season in Moroni usually lasts from November-December to April. During these months, average daytime temperatures confidently stay above 25°C, reaching highs of about 26.7°C - 27.3°C (for example, in December and March). Nights are also very warm, with minimum temperatures rarely dropping below 23.4°C - 24.3°C. The "winter" or drier and slightly less hot period falls on the months from May to October. At this time, average temperatures decrease slightly: daytime highs range from 23.9°C (in July) to 25.9°C (in May and October), and nightly lows can drop to 20.7°C (in August), bringing a light and pleasant freshness.

Daily temperature fluctuations in Moroni are small. The difference between the average maximum and average minimum temperature for the month is usually between 2.6°C and 3.8°C. This means that even after sunset, the air remains warm, and sharp temperature changes between day and night are not observed. The greatest daily fluctuations (about 3.5-3.8°C) occur in the period from August to November, when nights become relatively cooler compared to daytime warmth.

In Moroni, there is a fairly clear division of the year into two seasons based on rainfall, although the total volume of moisture remains moderate. The city does not experience a period of heavy torrential rains; rather, it is a matter of the frequency of rainy days, which changes noticeably throughout the year. Snow is not characteristic for Moroni, given its tropical location.

The wetter season in Moroni usually falls on the period from December to April. During this time, the number of days with precipitation is at its maximum – up to 26 days per month (January-April). January stands out as the wettest month in terms of total rainfall, reaching 11 mm. February follows with 7 mm, while March and April bring about 6 mm of rainfall each. Despite the large number of rainy days, the volume of precipitation suggests that these are most likely light or short-lived rains.

From May to November, a drier season sets in Moroni. Rainfall during this period decreases significantly. The driest months are July, August, September, and October, when only 1 mm of precipitation falls. The number of rainy days also decreases, reaching a minimum of 12 days in August, September, and October. In May, June, and November, about 2 mm of rainfall occurs, and the number of rainy days ranges from 16 to 19. Even in the driest period, the chance of catching rain remains, but it will be rare and likely very weak.

When planning a trip to Moroni, it is important to consider its warm tropical climate. Year-round, you will need light, breathable clothing made from natural fabrics such as cotton or linen. Be sure to bring sunscreen with a high protection factor, headwear (a hat or cap), and sunglasses for protection against the bright sun. Comfortable footwear, such as sandals, flip-flops, or light breathable trainers, is ideal for walking around the city and beach holidays.

Although the temperature in Moroni remains comfortably warm throughout the year, it is worth paying attention to the seasonality of rainfall. From December to April, a wetter period is observed with frequent, though usually not heavy, rains (up to 26 rainy days per month). At this time, a light waterproof raincoat or a compact umbrella will come in handy. Clothing made from quick-drying materials will also be very useful. From May to November, rainfall decreases significantly, but the likelihood of brief rain still persists, so a small umbrella might prove useful during this period as well.

Given the consistently high temperatures, the principle of layering clothing for Moroni is more about readiness for sudden rain than for cold. However, a light cardigan, shawl, or pareo may be useful for evening walks by the ocean if a light breeze picks up, or for protection against air conditioning indoors. Do not forget insect repellent as well, especially if you plan to spend time outdoors in the evening hours or visit nature areas.
