When to Go to Sydney
The best times to visit Sydney are in late spring and early fall (autumn). The spring months of October and November are pleasantly warm, although the ocean is slightly cool for swimming. The summer months of December through February are typically hot and humid, February being the most humid. In the early-autumn months of March and April weather is typically stable and comfortable, outdoor city life is still in full swing, and the ocean is at its warmest. Even the coolest winter months of July and August typically stay mild and sunny, with average daily maximum temperatures in the low 60s.
