When to go
Paris is warmest in July at 20.0 °C but brightest in June, averaging 12.1 hours of sun a day — the two do not always coincide, which is worth knowing before booking. Its coldest is January at 4.9 °C.
Staying there
A hotel room in France emits about 6.7 kg CO₂e per night under UK Government 2026 factors, so a week adds roughly 47 kg — about 6.0× the carbon of getting there by rail from Brussels.
How busy it gets
Paris records 22.9 overnight stays per resident a year (47,271,179 nights in 2025). A well-visited region, busy in season but not overwhelmed.
Eurostat, nights spent at tourist accommodation by NUTS 3 region, against resident population. Shown for context only — it plays no part in which destinations appear or in what order. Eurostat does not cover the United Kingdom after 2016, nor North Africa or the Levant at all, so this figure is absent for roughly a third of the destinations here.
