Although into the favourable and more consistent trade winds, the teams have not seen the blistering speeds they had hoped for due to the effects of a low pressure system in the South Atlantic.
Camper navigator Will Oxley said, because of the light conditions, the smallest details could determine who edges into a lead around the north east corner of Brazil.
"It's going to be very interesting to see how all this plays out," he said. "It's beautiful conditions but some very subtle differences could make a big difference."
The winds are expected to remain unreliable until after the fleet rounds Recife, expected to happen overnight (Sat-Sun NZT), meaning the consolidation of the fleet is likely to continue.
"Once we're past Recife the breeze will go behind us and we should be sailing deeper angles which is really our strong point so we should be in good shape," Oxley said.
"All in all, we're quite nicely positioned at the moment. Conventionally being to the west like we are is far from idea but these aren't conventional conditions, so we are sailing to what we have around us."
The current estimated time of arrival for the leading boat at the finish of leg six in Miami is May 8.
