When to go
Calais is warmest in August at 18.3 °C but brightest in June, averaging 12.7 hours of sun a day — the two do not always coincide, which is worth knowing before booking. Its coldest is January at 5.8 °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 10.4× the carbon of getting there by rail from London.
How busy it gets
Pas-de-Calais records 2.9 overnight stays per resident a year (4,185,081 nights in 2025). Comparatively quiet by European standards.
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.
