Molokai's weather mimics that of the other islands: mid- to low 80s year-round, slightly rainier in winter. Because the island's accommodations are clustered at low elevation or along the leeward coast, warm weather is a dependable constant for visitors (only 15 to 20 inches of rain fall each year on the coastal plain). As you travel up the mountainside, the weather changes with bursts of forest-building downpours.
