There is one potential downside to testing in Barcelona though, as the geographic location of the track means that the weather can make testing tricky. In 2018, for example, teams effectively lost one day of pre-season testing to bad weather – a snow-covered track made running an F1 car impossible. This year, however, the forecast looks much more promising with relatively mild temperatures and sunshine. But even on a fair day, temperatures are usually well below those that teams will experience when they come back a few months later for the Spanish Grand Prix. On a cold, overcast day in winter testing, track temperatures will rarely exceed 20 degrees Celsius and even on a relatively mild and sunny day they are usually in the range of 25 to 30 degrees. On a sunny day in May, however, when teams return to Barcelona for the race, the track can easily hit temperature of 40 degrees and more which has a big impact on the car and the tyres.
