International travellers flying in to Adelaide over the next few days will be warned to prepare for hot weather as a second heatwave approaches.
The mercury is expected to reach 40 degrees Celsius on Friday, ahead of 42C and 43C over the weekend and more days above 40C next week.
The State Emergency Service (SES) will hand out information at Adelaide Airport to incoming guests after they get off their planes.
Peter Nygaard from the SES says travellers may not be prepared for the extreme heat, particularly those from cooler climes.
"There's a lot of places around the world that are quite cold at the moment," he said.
"[We will] hand out some heat brochures so that people get a first-hand bit of advice from the SES as to what to expect and some of the precautions they can take like the covering up and hydrating and looking after each other."
Tomorrow could be the seventh January day to reach 40C this year, a feat that last occurred in 1908.
