How The Month Feels
Expect warm daytime weather (about 23.8°C) with humid air, plus a good chance you’ll encounter rain more than once. Sunshine is present but not dominating, so you’ll likely alternate outdoor walks with museum time.
What To Lock In Early
Because July comes with high crowd and price levels, reserve any museum-anchored plans you care about and lock key landmark visits early. Keep your schedule flexible for rain windows so you can shift emphasis between outdoor sights and indoor attractions.
