The last time the city made it into the 20s was back in May when the temperature topped out at 22.
The Bureau of Meteorology says Geelong residents can expect a mostly sunny Thursday, although strong winds will make many locals hesitate before heading outside to catch some rays.
The BoM has issued a Severe Weather Warning for parts of the Otways and the Surf Coast, especially between Apollo Bay and Anglesea, with winds of between 50 and 60km/h and possible damaging gusts of up to 90km/h.
The wind should ease this afternoon but will redevelop when a cold front moves through on Friday morning.
