Naughty Nina keeps raining on my parade
The wet season in Borneo is usually during November to March, when the northeast monsoon is blowing. The dry season in Borneo starts normally in April, though this year La Nina seems to be having a strong effect upon us.
During the summer months the air quality may suffer due to forest fires. Transport may be difficult during the dry season due to the low water level in some rivers and therefore some villages, longhouses and interesting sights inland may be difficult to reach. – visitborneo.org
There’s a good description of the El Nino and La Nina effects here (in French) and there’s a very amusing description of the effects of these phenomena upon the USA at the moment, apparently by Forest Gump!
The stresses these pseudo-periodical weather patterns place upon ecosystems are compounded when one closely follows the other, as is happening at the moment. You can look at my previous post on El Nino and La Nina to see how these events may effect wildlife here, espicially the sun bears.
