It's obviously impossible to say because no-one knows what the weather will be like in a month's time! All we can say is that northern Spain and the Pyrenees have suffered very heavy snow in the past two winters.
If you approach Spain on the Mediterranean side of France, the motorway goes up into the mountains for the border crossing but it's up in the heughts for a relatively short period before it comes down to near sea level again in NE Spain.
If you approach on the Atlantic side, the motorway crosses the border at a low level at Irun, but at some point you have to cross the higher ground in central north Spain in order to get over to the Costas, and you will be higher for longer in that case. And don't even think about crossing the border on the smaller roads in the central Pyrenees!
It's all about the weather. If you can, make a late decision with an eye on the forecast.
