November is shaping up to a disappointing month for those hoping for some late-Spring heat. So far this month, the city has experienced it coolest November day since 2006, with the mercury only climbing to 17.1 degrees on the 4th. This month has seen onshore winds dominating, thanks to high pressure remaining firmly anchored in the Tasman, which has lead to a feed of cool maritime air across the region. This pattern of weather is set to stick for the remainder of spring, meaning there is a good chance Sydney's Observatory Hill will not record a temperature above 30 degrees in November, which has not happened in 10 years. There will however be a brief warm spell around Friday and Saturday of next week, as a trough approaches from the west, which will see temperatures climb into the mid-to-high 20's. Despite the cool feel, the UV index will range from extreme to very high through this week, so remember to slap on some sunscreen if you are outside for an extended period of time.
