Coffee (NYBOT): (High: May. Low: July or September-October.) Weather in the Northern Hemisphere most affects consumption, with weather in the Southern Hemisphere most likely to affect production adversely. Demand strong through European and U.S. cool weather (rally into September deliveries). Market prices risk-premium going into Southern Hemisphere freeze season before demand collapses (July deliveries) into Northern summer heat.
