Firefighters on Sunday were battling around 50 wildfires after an unprecedented drought in the region and soaring temperatures, which have reached the highest in a century.
The 30 French soldiers from a Civil Defence unit landed shortly after midnight on Monday in Stockholm, an AFP correspondent said. They will be joined by another 30 firefighters from the south of France later in the day.
France has already sent two Canadair planes to Sweden after authorities asked for EU emergency help to fight the blazes, which have caused no fatalities so far.

There has been practically no rain since the beginning of May in the country, aside from a paltry 13 millimetres that fell in mid-June.
Denmark, southern Norway and northern Finland are also experiencing a period of extreme heat which, according to weather forecasts, is unlikely to end soon.
