Avaí's transfer window was marked by the arrival of several new players, including Bruno Ferreira, Caio Suassuna, Cipriano, Felipe Vizeu, Filipinho, João Vitor, Léo Chú, Pedrão, Rildo, and Léo Araújo. The new signings include three defenders and six forwards, with the club failing to sign any new players for the midfield position. Notably, Caio Suassuna and Filipinho were announced on the last day of the transfer window.

Among the departures, Thayllon has a contract with Avaí until December 2029, despite being loaned to Los Angeles FC until June 2027. The club also lost five players, including João Maistro and Sorriso, who were loaned to Atlético-GO and Palmeiras, respectively. Gaspar, who was on loan to Caxias, returned to Avaí and is now registered with the BID to be available to coach Allan Aal.

Avaí's next match is against Vila Nova on September 14, 2026, at 21h30 at Ressacada.
