The Bureau of Meteorology has forecast hot to very hot and dry northerly winds which will hit fresh to strong and gusty before a cold front begins to make its way from the west.

Fire bans are expected to be set in nine districts across Thursday.

Country Fire Service state duty commander Yvette Dowling said people should follow fire ban guidelines to minimise the risk of fire.

"We also want to remind farmers if you are out harvesting to make sure that you're abiding by the harvesting code of practice," she said.

"Also, if people have been burning over the last couple of weeks can they please make sure they are checked and extinguished in the areas where there are total fire bans."

It is also predicted there will be areas of raised dust through the western districts, the Flinders and parts of the North East Pastoral which could impact regions across the state.

State Emergency Services chief of staff Derryn Halliday said the dust could cause a number of problems for people with medical conditions such as asthma and other lung conditions.

"As we have seen previously over the past couple of months, the dust creates limited visibility on the roads so we ask people to be extra vigilant on the roads, make sure they have suitable stopping distances, and where necessary pull over to the side of the road to let the dust pass so they can proceed safely," he said.

The cooler change will beginning in the far west and should cover South Australia by late evening.

There is a strong wind warning for marine waters in the Upper West Coast, Lower West Coast, Central Coast, South Central Coast, Spencer Gulf, Gulf St Vincent, Investigator Strait and Adelaide Metropolitan waters.

There will be relief on Friday, with temperatures dropping back to the high teens or low to mid 20s before it begins to rise again at the start of next week.

There will be high risks as strong winds could add to fire risks on Thursday, but continued strong gusts could present another danger in coming days.

Winds will continue to be strong and gusty with warnings of sea and swell offshore reaching 5-7 metres on Friday and Saturday.

There will be chance of showers and thunderstorms in areas across the state over the weekend.

On Monday temperatures will begin to rise from cool to mild, then on Tuesday, October 30 it will be warm to hot ahead of a late change in the west.
