It really is all about the weather in the motorsport world this weekend.

Formula 1 is in Malaysia, and word from the paddock in Sepang is that it’s been raining around 4-5pm every day. Both qualifying and the race start at 4pm local time (9am in the UK), so everyone is predicting rain to affect proceedings. Twitter is the place for photos of the rain, from the likes of Claire Williams and Jake Humphrey – though his photo of the looming storm just before it erupted is more dramatic. The question, then, is whether rain will spice up the race, like last weekend’s Australian Grand Prix; or bring it to a premature end, like last year’s Malaysian Grand Prix. Fingers crossed for another fun-packed race.

It’s significantly drier for Rally Jordan. For my money, it’s been a good start to the WRC season. It was all too common last year that drivers would avoid being first on the road on day two, by slowing down at the end of day one to ensure they don’t lead the rally. That didn’t happen in Mexico, which was brilliant: they just properly gave it some, chief amongst them the excellent Petter Solberg. He’s not going to do the same in Jordan, which is a massive shame. It’s a rubbish rule that needs to change.

Back in the UK, the BTCC is happily living up to British stereotypes, going on about the weather on its website. It is a bit of luck though: Sunday’s looking like the best day of the weekend at Thruxton, the venue for the first meeting of the season. Jason Plato is the clear championship favourite, but I’m rather excited about it all.

There’s more of a chance of rain for the first rounds of British Superbikes at Brands Hatch on Monday, but it can’t be worse than the snow that cancelled the same meeting in 2008. I don’t think there’s anything resembling a favourite yet, but if we use World Superbikes as a guide, then the Suzuki could be worth watching. There’s a fascinating range of riders though, with successful riders returning to the series, last season’s runners up, and new guys moving up the ranks. Including the new Evo class, there are eight makes of bike in the championship. It all bodes pretty well.

It’s just as well MotoGP doesn’t get under way for another week, otherwise it really would be a ridiculously busy motorsport weekend. And I’d have to come up with a connection to the weather for that too.
