The climate is tropical. The eastern coastal belt is warm and comparatively dry; the southwest corner, hot and humid; and the north, hot and dry. There are two distinct rainy seasons in the south--May-June and August-September; in the north, the rainy seasons tend to merge. A dry, northeasterly wind, the Harmattan, blows in January and February. Annual rainfall in the coastal zone averages 83 centimeters (33 in.).

Volta Lake, the largest man-made lake in the world, extends from the Akosombo Dam in southeastern Ghana to the town of Yapei, 520 kilometers (325 mi.) to the north. The lake generates electricity, provides inland transportation, and is a potentially valuable resource for irrigation and fish farming.

Ghana's population is concentrated along the coast and in the principal cities of Accra and Kumasi. Most Ghanaians descended from migrating tribes that probably came down the Volta River valley at the beginning of the 13th century. Ethnically, Ghana is divided into small groups speaking more than 50 languages and dialects. Among the more important linguistic groups are the Akans, which include the Fantis along the coast and the Ashantis in the forest region north of the coast; the Guans, on the plains of the Volta River; the Ga- and Ewe-speaking peoples of the south and southeast; and the Moshi-Dagomba-speaking tribes of the northern and upper regions. English, the official and commercial language, is taught in all the schools.

Primary and junior secondary school education is tuition-free and mandatory. The Government of Ghana support for basic education is unequivocal. Article 39 of the Constitution mandates the major tenets of the free, compulsory, universal basic education (FCUBE) initiative. Launched in 1996, it is one of the most ambitious pre-tertiary education programs in West Africa. Since 1987, the Government of Ghana has increased its education budget by 700%. Basic education's share has grown from 45% to 60% of that total.
