Right weather condition for Postcrete

[spader]

I have been waiting for good dry warmish day for putting up a new fence post in the garden. I have got all the panels and wooden fence post, also postcrete concrete mix in a bag waiting, but it has been raining almost every day here. So they are on hold.

If it is drish day, then temperature would go down to 2 - 3C which is not ideal for the concrete setting.

Today it is very warm with temp 11C, but the ground is very wet and still see some drizzling with the rain in the garden.

Has anyone used Postcrete mix for securing fence posts? Is stated weather condition on Postcrete bag very strict? How dry does it have to be for good setting of the concrete?

When building the support stilts for my workshop I simply set the stilts vertical and to the correct height. I then poured the postcrete in dry and then sprinkled lightly with a hose as I knew it was going to rain later in the day. The rain did the trick and the postcrete set solid.
11C is an ideal temerarure because it goes off quite quickly.

Yeah some people seem carrying on with pouring concrete under heavy rain.

Those are air temperatures, not ground.

Ground only freezes for the top 150mm and only after several days of successive cold temperatures and typically in mid winter so that's around February
