I want to know the answer to the following question:
What frequently blankets San Diego in May and June?
All the background I'm provided with is that "Frequently, particularly during the "May gray/June gloom" period, a thick "marine layer" cloud cover will keep the air cool and damp within a few miles of the coast, but will yield to bright cloudless sunshine approximately 5–10 miles (8.0–16.1 km) inland.". Is that enough to answer the question?
