When to go
Cartagena is warmest in August at 27.6 °C but brightest in July, averaging 13.5 hours of sun a day — the two do not always coincide, which is worth knowing before booking. Its coldest is January at 12.6 °C.
Staying there
A hotel room in Spain emits about 7 kg CO₂e per night under UK Government 2026 factors, so a week adds roughly 49 kg — about 4.3× the carbon of getting there by rail from Madrid.
How busy it gets
Murcia records 3.6 overnight stays per resident a year (5,710,567 nights in 2024). 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.
