YOU might have been caught with a few too many layers on yesterday as spring sprung upon Launceston with a vengeance.
Yesterday marked the hottest day for the first week of September on record with a warm 20.9 degrees at 3pm.
It's an improvement from 1998's record of 19.8 degrees on September 2.
The overall September record of 24.8 degrees, reached in 1987, is a fair way off as temperatures are forecast to drop to 14 degrees on Sunday.
Bureau of Meteorology climatologist Lorien Martin said warm days weren't a surprise.
``Winter was warmer overall,'' Ms Martin said.
``There are warm sea surface temperatures around Tasmania, which are an added source of warmth and north-westerly winds are bringing warm air from the mainland.''
Reptile Rescue state co-ordinator Chris Daly said days like yesterday were perfect for snakes.
He dismissed claims it wasn't warm enough for the reptiles and said an overcast 20-degree day was ideal. ``We sweat to cool down - with snakes, their blood boils and it kills them,'' Mr Daly said.
``The season for snakes started yesterday.''
Mr Daly advised people to download Reptile Rescue's smartphone app or call the business on 0407 565 181 if in need of assistance.
