May weather forecast
Eritrea

May in Eritrea heralds the onset of summer, characterized by a substantial increase in temperatures across the nation. The country's diverse topography continues to play a role in the varying climatic conditions observed in different regions.

Compared to April, May presents significantly higher temperatures across Eritrea, marking the country's shift into its hot season.
