I got soaked riding to work just now, with light to moderate rain for the whole 1 hour commute.
Melbourne's weather has been odd lately: after one of the hottest Decembers ever (which is our first month of summer over here), and with thick smoke from massive bushfires covering Melbourne, January and February were completely different (a welcome change, actually). In my part of Melbourne, the January rainfall total was almost triple the long-term average, and February rain was about double the long-term average. January was a lot cooler than December, and February had average maxima about 2 degrees lower than the long-term average. I also just noticed that my area received about 42mm of rain in the last 8 hours.
I've done a "cannelloni wrap" of various bits of cycling clothing, and my cycling shoes, using newspaper, so they're not too soggy when I put them on to ride home. This weekend, when I'm not too busy packing for my upcoming house move (Friday next week), I'll be giving the poor bike a very thorough clean.
