Yesterday? I distinctly remember it raining yesterday! Maybe not where you were but it wasn't hot (BOM tells me it got to 21/22C at Cape Leeuwin & Cape Naturaliste).
Yes, it wasn't much more than low to mid 20s but it seemed hot on the sand tracks with the breeze at our backs. And I still have cold Canadian blood in my veins.
Yeah I know what the heat's like down that way from the Raid that we did around MR many years ago but I think that was around mid-30s and caused many a team to self-combust.
