Climate
Walcha has a cool climate with some snow falls and frosty nights, producing extremely low temperatures, during the winter months. However, frosts are usually followed by clear sunny days. In autumn, the town has the changing colours of the trees which make for great photographs. But it is summer that is arguably the best time to visit Walcha, although even on warm sunny days the temperature can suddenly drop. Due to its altitude, the town is rarely humid, and even days where the temperature reaches 33°C are tolerable. Be prepared for a sudden drop in temperature at anytime of the year by bringing adequate warm clothing.
During a very cold night untreated summer diesel fuel can "gel" turn from a liquid to a semi-solid. At temperatures below freezing, diesel engines may experience starting problems and warm-up slowly. As the morning warms usually before 9AM, the vehicle will operate normally without intervention.
