The city of Iquitos features a typical equatorial tropical climate, characterised by hot and humid weather throughout the year. Temperature fluctuations between months are minimal: the average temperature stays steadily in the range of 26°C to 28°C. This means travellers can expect warm days and nights regardless of the travel season.

Instead of the usual four seasons, the climate in Iquitos is divided into periods with varying rainfall intensity. However, judging by the data, rain here is an almost daily occurrence. Even in the "driest" months, such as August and September, there are about 18-20 rainy days. The wettest months are March and April, when the number of days with precipitation reaches 28. At the same time, the volume of precipitation is not always large, which may indicate frequent but short tropical showers.

Thus, when planning a trip to Iquitos, it is worth preparing for constantly high humidity and frequent rains. Light, breathable clothing and reliable rain protection, such as a raincoat or umbrella, will be your faithful companions at any time of the year. Consistently warm weather makes this corner of Peru accessible for visiting year-round, especially for those who love the rainforest atmosphere.

The climate in Iquitos is characterised as typically equatorial — it is hot and humid throughout the year, and the usual division into four seasons is practically absent. Temperature fluctuations during the year are minimal, creating a feeling of eternal summer. The average annual temperature holds steadily within a very narrow corridor, varying only from 25.8°C in July to 27.6°C in October.

The hottest period falls on September and October. At this time, the average daytime temperature often exceeds 31°C, while nights remain very warm, with figures around 23-24°C. The "coolest" months can conditionally be called June and July, when the average temperature drops to 25.8-25.9°C. However, even at this time, the daytime heat persists, although it becomes slightly less intense, with maximum values around 29°C.

Diurnal temperature fluctuations in Iquitos are more noticeable than seasonal ones. While days are almost always hot and sultry, with temperatures around 30°C, nights bring pleasant relief. With sunset, the air cools down to a comfortable 22-23°C. This drop makes evenings and early morning hours the ideal time for walks and exploring the city without the exhausting daytime heat.

The climate in Iquitos is characterised by high humidity and frequent precipitation throughout the year, which is typical for an equatorial region. The city has no classic dry season; however, periods with more and less intense rains can be distinguished. Travellers should be prepared for precipitation at any time of the year, as even in the "driest" months, more than half the days are rainy.

The wettest season in Iquitos lasts approximately from December to May. The peak of precipitation falls on March and April, when the number of rainy days reaches 28 per month, and the precipitation level becomes the maximum for the year. During this period, rains occur almost daily, often in the form of heavy tropical downpours, which can be both short-term and prolonged.

A relatively "dry" period occurs from July to September. The driest month of the year is considered August, when the amount of precipitation is minimal, and the number of rainy days decreases to an average of 18. Despite this, the probability of rain remains high. Precipitation at this time most often takes the form of short but intense showers, which are quickly replaced by sunny weather.

When planning a trip to Iquitos, prepare for typical Amazon jungle weather — it is hot, humid, and rains frequently throughout the year. The foundation of your wardrobe should be light and breathable fabrics, such as cotton, linen, or modern synthetic materials that dry quickly. The temperature rarely drops below +22°C even at night, so warm clothing is unlikely to be needed. However, a key feature of the climate is the high probability of precipitation on almost any day, regardless of the season. Therefore, a waterproof jacket or rain poncho is an absolutely indispensable item in your suitcase.

For walks around the city and excursions, choose comfortable clothing: t-shirts, shorts, light dresses, and trousers. It is also recommended to take a few items with long sleeves — they will be useful not only for protection from the strong equatorial sun but also act as a barrier against insects, especially during jungle outings. Regarding footwear, give preference to comfortable water-resistant trainers or closed sandals. Open shoes can be uncomfortable on wet streets after rain. Do not forget headwear, sunglasses, and high SPF cream — the sun here is very active even on cloudy days.

Although there is no sharp change of seasons in Iquitos, a wetter period (from March to May) and a relatively "dry" one (from July to September) are conditionally distinguished. However, even in the "dry" months, rain is a frequent occurrence, so your set of items will not change much depending on the trip date. Besides clothes, be sure to put insect repellent in your suitcase, as you are heading into the heart of the Amazon. A small backpack for day trips and a waterproof bag to protect documents and electronics from moisture will also come in handy.
