First things first, if it’s hot enough where you don’t want to leave the comfort of your air conditioning or cold enough that you need to put on a hat and gloves, you shouldn’t lay concrete!

It’s advised that concrete be cured at a moderate temperature between 50 °F – 90 °F. In a perfect world, the temperature of fresh concrete should be above 50 °F, but cured and maintained at 50 °F. But if you can’t hit the 50-degree mark spot on, concrete cured within these temperatures will outperform +90 °F concrete in strength and durability.

But, that may be for ideal strength on something like a home foundation or driveway. It may not be as big a deal for bricks.
