What temperature is too hot to lay bricks?

We've got brickwork planned for later in the summer and I've heard extreme heat can cause problems with the mortar. Is there a temperature above which you shouldn't be laying?

"I would personally say between 30 - 32 degrees unless you was in the shade with keeping the bricks damp and the motor wet to try and prevent cracking and drying out to quickly thanks andy"

"You can lay in most heat however making it slightly wetter would be beneficial but not much concern over this as the worst that could happen is the mortar joints crack and then you would just need to repoint at a later date"
