Rains all winter here in Victoria. Were I was previous, Manchester and Cheshire UK, it'd rain fall, winter, spring and summer. It was always raining it seemed. Lots of guys in the region here complain about the rain....they should move to the British Isles, little wonder its so green there. Ireland, the emerald Isle....its always raining.
Its nice if you have enough work that you can drop onto easier jobs in the wet, but its just not always possible. You need to know your limitations for sure. And then theres the added element of wrecking peoples gardens....because the ground is saturated and soft. Its a pita, but you still have bills to pay. They wont wait for the sun to come out. For me, high wind is far more menacing.
