‘ Note. —lu 1907, August was the month iii which most rain fell. The heaviest daily rainfall was on 
.August 15th, and amounted to 45 mni. 
From about the middle of November to the beginning of March, the climate as a rule is 
excellent, with the e.xception of occasional hot snaps, often occurring about the end of December 
or beginning of .January, and high winds associated with dusty days in February. With these 
exceptions Khartoum enjoys bright sunshine, a dry heat tempered by cool breezes—occasionally 
too cool, perhaps—and comparatively cold nights. There is not, as a rule, however, that sudden 
change in temperature so liable to induce abdominal complaints and chills. On the whole, 
during these favoured months, the climate may be said to be equable. It will bo seen that the 
lowest temperature in the year is usually recorded in January or December. 
From March onwards the temperature commences to rise, and attains its maximum in 
April, May, or June. From the beginning of July to the end of September may be termed the 
rainy season proper, though a few showers may occur in May and June, and there may be 
a considerable fall in October. One has known a few drops of rain occur in March, but, 
as will be seen from the table, the rain-gauge record for the first six months is invariably nil. 
The months of May, June, and July especially are, as a rule, made exceedingly unpleasant by 
tbe visit of sand-storms, winch may turn day into night and night into a period of torment. 
They usually sweep down upon the town from the south, and are sometimes followed by 
torrential rain and accompanied by thunder and lightning. They vary much in frequency and 
duration. Sometimes there may be three or four in the course of a week, at other times a 
week or ten days may elapse without any such disagreeable exhibition. They may last a few 
minutes or many hours. One of a peculiar type endured for 48 hours, and well-nigh rendered 
life unendurable. 
These haboubs have a marked effect on health conditions, as they tend to occur about 
nightfall, often ruin a night’s rest, and may carry infected dust into food and drink, while the 
woiTy and annoyance to which they give rise, play no small part in producing that nervous 
irritability so characteristic of the Tropics.
