I feel that it was the off and on rain that drained from the pole and over the concrete. The curing of concrete is a chemical reaction, not a water ratio or humidity problem. concrete achieves its maximum strength in seven days. Check to see if you can scratch deeper than already, as the current surface is probably a leaching of the fine sands and concrete from the rain and shouldn't be much more than 1/4 to 1/2 inch. The rest will be, well, concrete.
