This is more prevalent in winter as the temperatures are lower and it's more easy for condensation to form. The most likely cause is a defect in the spacer placed between the window and the frame. The spacer usually contains desiccant that is highly absorptive and can absorb excess moisture.
This could lead to water leaking through the gap once the desiccant is saturated. double glazing repair can cause condensation and water to build up in the gap, which is difficult to get rid of.
