So why is it so hot?
The BoM explains that a high currently sits over the Tasman Sea and a trough is located over central NSW, directing a hot northerly airstream over the state.
This trough is forecast to move north in response to a cold front slipping south of the state, bringing a milder southerly change to western and southern districts.
The change should move through the remainder of the state on Thursday, although high temperatures will remain over the northwest.
Following the change, another high pressure system will move across southern Australian and over the Bight, before the next trough is expected on Friday.
As of 7.30am the temperature is listed by the BoM in Casino as 25.9 degrees but "feels like" 26.1, Lismore as 22.3 degrees but "feels like" 25.1, Ballina as 24.3 but "feels like" 26.3 and Byron Bay as 22.8 but "feels like" 24.
