July arabica coffee was little changed at $1.4590 per lb.
The Brazilian real hit a 2-1/2 month high versus the dollar on Wednesday, deterring farmers and exporters from selling by lowering returns in local currency terms.
Farmers said more downpours this month would be crucial to avoid a decline in the harvest from July and to improve the quality of the beans, especially since temperatures have been high.
"The trees need more rain because it's very hot," said Kouassi Kouame, who farms in the western region of Soubre, at the heart of the cocoa belt.
Ivory Coast's 2020/2021 cocoa mid-crop harvest started on April 1 and will end Sept. 30.
About 7,000 tonnes of beans were delivered to Abidjan port and 3,000 tonnes to San Pedro between April 1 to April 4 for a total of 10,000 tonnes, down from 16,000 tonnes during the same week last season.
Farmers said good moisture content in the soil had helped plenty of small pods develop on trees - a strong start for the April mid-crop compared with the same period last year.
"Without upkeep of the plantations, production could fall," said Albert N'Zue, who farms near Daloa.
"You have to adapt or lose a lot of money on LID," a director of an Abidjan-based international cocoa company said, requesting to remain anonymous because of the sensitivity of the issue.
Exporters said most of the cocoa purchased between October and December will now be used to honour around 80% of the January-March contracts.
