Aracaju welcomes guests with a typical tropical climate that provides warmth all year round. The temperature here is distinguished by enviable stability: monthly averages fluctuate insignificantly, from approximately 23.8°C in July to 27.7°C in February. This means you can count on comfortable warm weather regardless of the season of your visit to this Brazilian city.

Although sharp temperature jumps are not observed in Aracaju, periods with varying precipitation activity can be distinguished. According to the data provided, from March to July the number of days when rain is possible increases, reaching a maximum in June-July (26-27 "wet" days per month). Remarkably, total rainfall remains low throughout the year, with a peak of just 5 mm in May. This may indicate frequent, but predominantly light or short-lived rains during this period. Drier weather with fewer wet days (13-14 per month) and minimal precipitation (1-2 mm) usually sets in from October to December.

Thus, when planning a trip to Aracaju, one should expect predominantly warm, and at times hot weather. Light clothing will be appropriate at any time of the year. If you prefer to minimize the likelihood of even light rains, then the period from October to December may be the most preferable. In other months, especially from March to August, it is worth being prepared for possible, though usually not heavy precipitation, which can bring refreshing coolness to the tropical heat.

In Aracaju, located in Brazil, a tropical climate prevails with high temperatures throughout the year. The annual range of average temperatures is relatively small, ensuring comfortable conditions for relaxation. The hottest month is usually February, when the average temperature reaches 27.7°C, and daily highs can rise to 30.6°C. The "coolest" month is considered to be July with an average temperature of 23.8°C, while minimum night temperatures drop on average to 21.7°C.

The summer period in Aracaju, which conventionally falls on the months from December to March, is characterized by consistently hot weather. Average monthly temperatures at this time range from 27.1°C to 27.7°C. During the day, the air warms up to 30-30.6°C, creating a hot atmosphere typical for the tropics, which is often accompanied by high humidity given the significant number of days with precipitation. Nights also remain very warm, with temperatures rarely dropping below 24°C.

The "winter" months, roughly from June to August, bring some relief from the heat, but the weather remains very warm and pleasant. Average temperatures during this period hold in the range of 23.8°C - 24.5°C. Daytime highs reach 25.9°C - 26.6°C, and nighttime lows drop to 21.6°C - 22.5°C, which can be characterized as mild warmth. Temperature fluctuations between day and night in Aracaju during the year are not too significant, averaging from 4°C to 6°C, which is typical for coastal tropical regions.

In Aracaju, precipitation falls exclusively in the form of rain; snow is uncharacteristic for this tropical region. The city demonstrates pronounced seasonality in moisture distribution, with a fairly smooth transition from wetter to drier periods throughout the year. Although the total annual rainfall can be characterized as low, the nature of the rains changes noticeably from month to month, influencing the perception of the weather.

A period with increased humidity is usually observed from March to July, gradually reaching its peak by the middle of this stretch. May is the month with the highest average amount of precipitation (about 5 mm), while July stands out with the maximum number of rainy days (on average 27 days). An interesting feature of the Aracaju climate is that the month with the highest recorded rainfall volume does not always coincide with the month where the maximum number of rainy days is noted. This means that in certain periods of the wet season, rains can be more concentrated and intense, whereas in others — more frequent, but drizzling and less abundant, stretching over a larger number of days. Such variability suggests that precipitation can manifest both in the form of short, refreshing showers and in the form of more prolonged, but light drizzle.

The dry season is most clearly expressed from October to December. At this time, both rainfall volumes and the number of days with rain decrease to their minimum annual indicators. October and December are the driest months in terms of rainfall amount (on average 1 mm), and November and December — in terms of the lowest number of rainy days (about 13 days). Rains become a rare phenomenon, and if they happen, they are usually very insignificant. Transitional months, such as August and September, as well as January and February, are characterized by a moderate amount of precipitation, acting as a kind of buffer between humidity peaks and dry periods. It is important to note that even in the rainiest months, an analysis of the ratio of total rainfall volume to the number of rainy days suggests that prolonged torrential rains are less characteristic for Aracaju, giving way rather to short-term or moderate precipitation.

When planning a trip to Aracaju, it is important to consider its warm and humid tropical climate, which is characteristic of this region of Brazil all year round. The average annual temperature fluctuates slightly, remaining comfortably warm, so the basis of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton and linen. T-shirts, shorts, sundresses, light trousers, and skirts will be the most suitable choice. Do not forget a swimsuit, as the beaches are one of the city's main attractions. Given the high solar activity, be sure to pack sunscreen with a high protection factor, headwear (a hat or cap), and high-quality sunglasses.

Although the temperature in Aracaju remains high throughout the year, periods with varying amounts of precipitation can be distinguished. The greatest number of days with rain falls on the period from March to August, with the peak of precipitation usually observed from May to July. In these months, despite the fact that the total amount of precipitation may not be very large, rains can be frequent, so a light folding umbrella or a compact raincoat will be very handy. From September to February, the amount of precipitation decreases noticeably, and the days become sunnier. Regardless of the season, evenings can bring a slight coolness, especially if a breeze blows from the ocean, so a thin sweater, cardigan, or light jacket may come in handy — the principle of layering will be very useful here.

Comfortable shoes are extremely important. For walking around the city and sightseeing, choose light sneakers or comfortable sandals. Flip-flops are perfect for the beach. It is also worth taking insect repellent with you, especially if you plan evening walks or visiting green zones. In general, your luggage for a trip to Aracaju should be oriented towards hot weather, sun protection, and possible short-term tropical downpours.
