There are basically two types of windconditions in Tarifa. Either a easterly off-shore wind called the Levante or an on shore Atlantic breeze from the west. They deliver significantly different conditions.
Levante is the off shore wind condition in Tarifa at 18-35 knots. It's often gusty and needs a couple of days to stabilize. Also the strength of wind really differs specific locations. Close to the center at Balneario it is strongest and it dissipates in force towards the north. Levante leads to flat conditions with minor Atlantic swell. Rescue boats are out with Levante. Palmones at Algeciras is a good alternative if you are looking for on shore kite spot with Levante.
Poniente or the Atlantic wind blows on shore at 12-25 knots. It's more stable than Levante and provides ideal kiting conditions along the Los Lances beach. Conditions are wavy.
