The more unhealthy parts, in each case only during the period immediately succeeding the rains or the Nile flood, are, in the order of the evil, the Bahr El Ghazal, the Upper White Nile, the Upper Blue Nile, Kordofan, Kassala, and Suakin. During the rest of the year the climate is dry and healthy throughout. The temperature is, in the summer, undoubtedly hot, the thermometer having on rare occasions risen to as much as 126°; but on the other hand, except in the rainy season, the nights are always cool and refreshing. During the rest of the year, the temperature naturally varies considerably; but it may be said that the winter is bright and invigorating throughout, and not too hot. There are even unpleasantly cold winds at times. Except during the rainy season, the prevailing winds are, in the valley of the Nile, always from a northerly direction. In other parts, the wind varies according to season, but all get their share of the north wind.
