Expect heat that can shape your day
Milan in August suits travellers who enjoy warmth rather than those looking for mild sightseeing weather. Temperatures reach 30°C on 30% of days, so the average high does not tell the whole story: hotter spells are a realistic part of the month. Humidity averages 66%, which can add to the discomfort when you are walking around in the heat. Plan more demanding outdoor time for the morning, keep midday flexible and choose accommodation where you can cool down comfortably. Loose, breathable clothing is the practical choice. If hot city days tend to wear you out, August is not the easiest fit.
Plenty of sunshine, but keep a wet-weather option
August brings about 8.1 hours of sunshine a day within 13.9 hours of daylight, leaving plenty of scope for outdoor plans without having to pack everything into midday. Rain is still a meaningful drawback, not just a remote possibility. Carry a compact umbrella or light waterproof, and keep some indoor time flexible rather than committing every day to being outside. The rainy-day average does not mean your visit will follow a neat pattern, so check the forecast before deciding when to spend longer outdoors. This is a month for adaptable plans: sunshine is a strong draw, but reliable dryness is not.
