The climate in this region is distinguished by stable warmth throughout the year, which is typical for the southern part of the country. Warri welcomes travellers with high temperatures that rarely drop below comfortable values. The hottest month is usually February, when the air warms up to an average of +29.2°C, and daily maximums reach +33.7°C. Conversely, the "coolest" period falls in the middle of the year — July and August, when the average temperature is around +25.5°C.
Interestingly, the usual concepts of seasons work differently here. The summer months (June-August) bring slight relief from the heat: thanks to cloud cover, the thermometer stays at the +28...+29°C mark during the day. The winter period, on the contrary, is characterized by higher readings. In December and January, despite the calendar winter, the weather is truly hot: daytime temperatures often rise to +33°C and above, making this time of year ideal for sun lovers, though it requires mandatory protection from active UV rays.
It is also worth considering daily temperature fluctuations, which change depending on the season. In drier months, for example in January, the difference between daytime heat and nighttime freshness can be around 10 degrees (from +33.6°C during the day to +23.3°C at night), allowing for a comfortable rest from the heat. In the rainy season, this contrast is smoothed out, and nights become only slightly cooler than days, stably maintaining the temperature at the level of +23...+24°C.
