Smog in Penang
One thing you should be aware of is that Penang does sometimes get affected by the smog that comes over from Sumatra in Indonesia, where an annual burning of the forests causes huge amounts of smoke from the underlying peat.
If the smog does come over the island, it usually occurs during the months of September and October.
Penang does not get as much smog as places to the south of Malaysia and Singapore, but occasionally it can be rather unpleasant!
