July resembles, to a great extent, the month which precedes it, except that, in all particulars the season is more moderate, showers are less frequent, there is less wind, and less absolute heat.

August.—In August the weather is charming, notwithstanding withstanding a slight increase of heat, owing to diminished evaporation; and the sun being now on its return to the equator, its power is felt in greater force on full exposure to its influence.

September.—The same atmospheric condition continues throughout September, but towards its close the sea-breeze becomes unsteady and clouds begin to collect, symptomatic of the approaching change to the north-east monsoon. The nights are always clear and delightfully cool. Rain is sometimes abundant.

October is more unsettled, the wind veering towards the north, with pretty frequent rain; and as the sun is now far to the southward, the heat continues to decline.

November sees the close of the south-west monsoon and the arrival of the north-eastern. In the early part of the month the wind visits nearly every point of the compass, but shows a marked predilection for the north, generally veering from N.E. at night and early morning, to N.W. at noon; calms are frequent and precede gentle showers, and clouds form round the lower range of hills. By degrees as the sun advances in its southern declination, and warms the lower half of the great African continent, the current of heated air ascending from the equatorial belt leaves a comparative vacuum, towards which the less rarefied atmospheric fluid is drawn down from the regions north, of the tropic, bringing with it the cold and dry winds from the Himalayan Alps, and the lofty ranges of Assam. The great change is heralded as before by oppressive calms, lurid skies, vivid lightning, bursts of thunder, and tumultuous rain. But at this change of the monsoon the atmospheric disturbance is less striking than in May; the previous temperature is lower, the moisture of the air is more reduced, and the change is less agreeably perceptible from the southern breeze to the dry and parching wind from the north.
