CLIMATE AND WEATHER
[Chap. I.
August. —Much cooler; air clearer and drier after the rain;
monsoon breeze and swell moderate or light, and the wind more
westerly at night. Sometimes heavy weather and rain occur.
Native craft go to sea again early in the month. On the western
5 part of the coast, the weather is the same as in July.
September. —The south-west monsoon usually ends about the
beginning of this month; light winds, with a decreasing swell,
but at times strong west-south-westerly winds, with a heavy swell,
continue up to the middle or latter part of the month. Light airs
10 and calms are common. On the western part of the coast, the
temperature continues very hot, with light variable winds and
an occasional fresh shamal. In 1872 there was an easterly gale,
with rain, lasting a few hours; this is exceptional.
October. —Fine, clear, and dry; light sea breezes, and calms;
15 land breezes usually very light, but occasionally fresh for a few
hours. Sea smooth.
November. —As in October; but sometimes about the middle of
the month, squally from eastward, with unsettled weather and
ground swell, probably due to bad weather to the south.
20 December. —Fine, with moderate land and sea breezes. The land
breezes are often strong towards the end of the month, when a
moderate gale from north-east to south-east, with rain, is frequent.
A shamal occurs at times on the western part of the coast. The
weather is usually clear, but the land is sometimes obscured by
25 dust. It is often exceptionally clear, and very cold after rain.
Sea generally smooth. In December and January, the bad weather

eastward.
Temperature. —The average temperature for the whole year is
30 about 75° at the head of the Gulf, increasing southward to about
80° at Lingeh and decreasing slightly towards the eastern part of
the Makran coast. The average for the year is about 82° at Muscat,
where the temperature of the cooler part of the year is higher than
in the other sections. The hottest period, in the Gulf, with an
35 average temperature of about 92°, is about August; but it tends
to come earlier in the year on the coasts subject to the influence
of the monsoon, which prevents any increase in temperature after
June or July. Thus the hottest month is June, with 93° at Muscat
and 87° at Pasni. The coolest month is January, with an average
40 temperature of 52° at Basra, increasing to over 60° in the southern
part of the Gulf, and to 67 0 at Jask. On the Makran coast the average
temperature in January is about 65°, and at Muscat 71°.
Extreme temperatures. —The greatest range of extreme temperatures
occurs near the head of the Gulf, where temperature is likely to fall
45 to about 40° each year, and to rise to about 110°. Occasionally tem
peratures below the freezing point occur, the lowest recorded at
Basra being 24°; the highest temperature recorded there is 122°.
In the northern part of the Gulf, generally, temperature may be
expected to range from 50° to 105° in the course of the year, but a
50 range of 41° to 109° has been experienced at Lingeh. At Muscat
the extreme range is from 49° to 116°, from Jask to Gwadar 41°
to 114°, but at Pasni 31° to 115°.
Temperature of the sea. —The conditions during summer in the
