Traveller notes on Catania in August
Other months in Catania
Catania's forum rates May as warm but not hot, with flowers in bloom and the tourist season not yet at its peak — daytime temperatures in the low-to-mid 70s°F with cooler nights that call for a light jacket. Regulars are honest that May weather can still be genuinely unsettled some years, with one visitor reporting an overcast, rainy stretch through most of the month, so layers and a rain option are worth packing alongside summer clothes.
