National Weather Service director Samuel Maiha says last week’s weather conditions were a result of various factors from the southeasterly winds and the occurrence of mixed clouds with October and December periods expected to bring the rains.
“This is temporary. There was this southeasterly winds and then there was this pulling effect from the north,” Mr Maiha said last Friday.
“There was a very strong typhoon up north around Guam so that tended to really enhance our theory that there was this pulling effect. As it went further up the influence and pulling effect weakened.”
This explained the cloud buildup experienced at the southern part of the mainland last week, where in the capital Port Moresby’s cloud cover was dense in the lower cloud levels.
“So when it went further that pulling effect kind of slackened down so this receded, the wind and what was building up at the equator kind of receded back and we were receiving what we call mixing clouds where we have what on the surface we have this weakening south east winds still there and on top we have these warm winds from the equator,” Mr Maiha said.
Asked when the rains can be expected for the wet season he said the usual average is about December 5.
“But usually we assume that the wet season must not come before October, it must come between November and January.”
