Alice: Hey, Mark! Have you decided when to visit North Sea this year?

Mark: Not yet, Alice. When do you think is the best time to go?

Alice: Well, from what I've read, September seems to be perfect. The weather is mild, and it's not too crowded.

Mark: Hmm, September... That sounds good. What about July or August?

Alice: July and August can be quite busy with tourists. It's peak season, so prices are higher and attractions are more crowded.

Mark: Got it. September it is then. Thanks for the tip, Alice!

Alice: No problem! I'm sure you'll enjoy your trip whenever you go.
