A Note on the Land and Sea Breezes of South Africa, 297 
Table 4 shows that wind directions in Delagoa Bay prevail in the 
south-east quadrant {i.e., from the sea) from October to March, being 
rather to the north of east-south-east from October to December, and 
slightly to the north of south-south-east from January to March ; whereas 
in the winter half of the year there is a small preponderance of direction 
from the land, say, from a west-north-west direction during April-June, 
and from nearly due north from July to September. (See Fig. 1.) 
Considering the total duration for the year of each wind direction we 
find that the commonest winds are south-south-west, east-north-east, and 
north-north-west, in order of frequency. That is to say, the prevailing

winds blow up or down the coast as they do at East London. The winds 
of secondary importance, namely, those from the north-north-west, are 
mainly a winter phenomenon. They occur also at East London at the 
same season, albeit the duration there is relatively less important than it 
is in Delagoa Bay. At both places they may fairly be regarded as arising 
from similar barometric conditions, and as blowing from the cooled 
interior to the warmer area dominated by the Mozambique Current. 
Besides being winter winds they are also essentially night and morning 
winds, for they appear but rarely in the afternoons. It is these winds 
that are usually responsible for the hot (foehn) winds of the coast belt 
during the late winter and early spring months.
