But more importantly if your spokes were properly tensioned last summer, regardless of the warming and cooling they experienced, they will come back to the same tension once you get back to the same temperatures this summer. Many of us have ridden through enough winters to confirm that the spoke tension change that may occur due to temperature change is so small that it has no effect on wheel performance. All that is not saying that something has not happened to your wheels. But if it has it was not because of temperature changes.
