El Marco's climate is southern one, with mild winters and hot summers. The average temperature is 17.5º C (63.5º F), although in July and August the vine endures temperatures well above 40º C (104º F!). The southwest wind off the Altantic brings the vines the right amount of moisture, especially during the summer at dawn.
The annual average rainfall is 600 liters/square meter (23.64"). These are just the right conditions for the vines to thrive, and for the grapes to ripen easily.
