Pike fishing in late winter/early spring. Fish when sunny or cloudy?

Hello, I am always very confused about the best weather for pike fishing. What's their behavior in this period? Outside temps between 1 and 8 C. On the one hand I'm thinking they get more active when the sun is out because of the warmth, on the other hand I've been reading pike don't like sunshine and they are more active when it's cloudy.

What's your experience?
