The north winds which blow for seven days before the heliacal rise of Sirius in the Mediterranean region. Compared with the later Etesiai, they are supposedly cooler. The seven days - like their purported relationship with Sirius and the nine days from their onset until the Etesiai - are arbitrarily determined [1; 2]. Their dates vary between 7 and 23 July (Julian calendar) (= 4 - 20 July in the Gregorian calendar).
