Commentary for Numbers 33:8

ויעברו בתוך הים המדברה, “they passed through the midst of the sea into the wilderness;” the same spirit (wind) that had helped them to enter the sea when coming from the desert on the other side, also helped them face the desert when emerging from the sea. (Tossaphot Erchin 15) This was the North wind that G-d had only activated in order to encourage the Egyptians to pursue the Israelites.
