The trend is clear: employers start advertising available summer jobs earlier and earlier.
"We can see that the ads come in earlier than they did previously," said Therese Landerholm, analyst at the national employment service.
There are currently over 16,700 summer vacancies, which is 40 per cent more than this time last year, when there were 11,400 summer jobs advertised.
But it is not clear whether this means that there will actually be more jobs available this summer. It could just be that the employers want to sort out the summer staffing in good time. In particular, it is the health care sector that seem keen to sort it out well in advance, said Therese Landerholm.
"There are loads of ads out now for different kinds of nurses and midwives. Of course there is a shortage of people in those professions, and all the more a reason to try to catch the ones that are there early," she said.
But there are also unskilled jobs on the lists for this summer, for shop assistants and stockroom workers and so on. Swedish Radio News went to a job centre in Stockholm where Elias Trabelsi is pouring over ads for stockroom workers.
"I'm here every day. I just send out my CV, send out my CV," he said.
Would you apply for a job in June, even though you need a job now?
"Oh, yes. But if a job then turns up that starts sooner, I'd drop the June job. That's what you have to do, keep several things going at once," he says.
Anyone looking for a summer job may want to have a look at the free app "Sommarjobba" from the employment service. In addition to ads for vacancies, it also contains advice about contracts, job applications, salaries and conditions.
