Yes you can! Fences may be installed in just about any weather with the exception of rain.
In extremely cold temperatures (32 degrees and below) you can add calcium chloride to your concrete mixture. Calcium chloride is an accelerating agent which when added to concrete will increase the rate of early strength or shorten the time of setting of the mixture. Calcium chloride is the most common accelerator used when speaking about concrete.
Avoid setting your fence posts in the rain! You can imagine all of the hard work that goes into digging post holes only to have them fill up with rain water. There is no reasonable way to excavate the holes to remove the water, so what you wind up with is a weak bond between your concrete and your posts. This scenario spells Disaster with a capital D.
