Owerri is characterised by a hot tropical climate with high humidity and consistently high temperatures throughout the year. Average thermometer readings range from +25°C in the "coolest" summer months to a hot +30°C in February. It practically never gets cold here, and even night-time temperatures rarely drop below +22°C, making the city a suitable destination for warmth lovers in any season.

The year in this region of Nigeria is clearly divided into two main periods: a short dry season and a prolonged rainy season. The dry period, falling mainly in December and January, is distinguished by minimal rainfall and clear skies, making it the most comfortable time for excursions. With the arrival of spring, the number of rainy days rises sharply, reaching its peak in September and October, when precipitation can fall almost daily.

A feature of the local climate is the smoothness of temperature transitions: there are no sharp spikes of heat or cold between seasons. However, travellers planning a trip from April to November should be prepared for frequent rains. Even in the wettest months, the air remains warm, creating the atmosphere of true steamy tropics, so light but waterproof clothing will be indispensable.

The climate in Owerri is distinguished by stable warmth throughout the year, so the concept of cold here is quite relative. The hottest period is the beginning of the year: the peak of the heat falls in February, when the average temperature reaches 30.0°C, and daytime highs can rise to an exhausting 36.1°C. The "coolest" season, if it can be called that, arrives in the middle of the year—in July and August, average figures drop to a comfortable 25.5°C, bringing relief after the spring heat.

The winter months (December, January, and February) in this region of Nigeria are paradoxically the hottest and driest. It is during this period that the most noticeable daily temperature fluctuations are observed. If during the day the sun warms the air to 34°C–36°C, by night it becomes significantly fresher, and the thermometer column can drop to 22°C–24°C. Such contrast makes evenings pleasant for walks, despite the daytime heat.

The summer period, conversely, is characterised by a more even and moderate temperature regime, which is connected to the rainy season and dense cloud cover. From June to September, extreme heat recedes: maximum daytime temperatures rarely exceed 29°C. At this time, the difference between day and night becomes minimal, creating an atmosphere of constant soft warmth and high humidity around the clock.

The climate in Owerri is defined by tropical conditions with clearly expressed wet and dry seasons. Precipitation here falls exclusively in the form of rain. The driest and most comfortable period for travel falls in winter: in December and January, the probability of precipitation is minimal, and the number of rainy days is only about 4 per month. This is the best time for those who want to catch sunny weather.

With the arrival of spring, the situation changes drastically. The rainy season begins in March, when the number of inclement days jumps to 21 per month. The wet period in this region of Nigeria is protracted and lasts practically until November. This entire period is characterised by high cloud cover and frequent downpours, which can be both brief and prolonged.

The peak of the wet season is observed from June to October, when rains become an almost daily phenomenon. The record holder for the frequency of precipitation is October, when up to 30 rainy days are recorded. Summer months (June, July, August) are only slightly behind, counting from 27 to 29 days with precipitation. If your trip is planned for this time, be sure to take a reliable raincoat and waterproof shoes with you, as dry days will be a great rarity.

Owerri welcomes travellers with a warm tropical climate all year round, so the basis of your luggage should be items made of light natural fabrics. Since the average temperature holds in the range of 25–30°C, and in the hottest months (January and February) can reach 36°C, give preference to cotton, linen, and viscose. These materials will allow the skin to breathe and ensure comfort even on sultry days. Be sure to take a wide-brimmed hat and quality sunglasses.

When planning a trip, it is important to consider the rainy season, which lasts from March to November. The peak of precipitation falls on the period from July to October, when the number of rainy days reaches 29–30 per month. At this time, a sturdy folding umbrella and a light raincoat that is convenient to carry with you will become indispensable. Footwear should be practical: for the dry season (December — February), light trainers or breathable moccasins are suitable, while for the wet period, it is better to choose quick-drying sandals or waterproof shoes resistant to mud.

Despite the fact that nights in Nigeria remain warm (about 22–24°C), it is recommended to take one light long-sleeved top or a windbreaker. It will come in handy not so much for protection from cold outside, as for a comfortable stay in rooms with strong air conditioning, and will also serve as an additional barrier against insects in the evening. Do not forget to also stock your first aid kit with high-factor sunscreen and effective repellents.
