When to travel
It is possible to visit Sicily all year long, but the best times to travel are May, June, September and October. Summer is lovely, but it can get very hot over July and August and the seaside resorts and towns can become crowded.
While the weather is quite changeable and sometimes rainy in spring, the summer months are arid and temperatures can go as high as 34 degrees. Once the temperatures fall in autumn, the rainy period begins. Temperatures fall further over the winter months, but apart from the higher areas, most of Sicily hardly ever experiences temperatures below freezing.
The northern and particularly the northeastern parts of Sicily get the most rain over the year, which is mainly down to the more mountainous terrain. Thunderstorms and heavy rainfall during the warm summer months are common, especially in the areas East of Mount Etna. The flatter plains in the southern and southwestern part of Sicily get relatively little rainfall throughout the year.

How to travel
The international airports in Sicily are Trapani in the west, Palermo in the northwest, Catania in the east and Ragusa in the southeast of the island. International connections within Europe are good and Sicily is served by all major and some regional European airlines. Direct long-haul connections from outside Europe are rare, in this case it is easiest to connect in mainland Italy like Milan or Rome.
It is possible to take flights from mainland Sicily to the island of Pantelleria from Trapani or Palermo.
The other islands can be reached by ferry. The hydrofoils for the Aeolian Islands leave from Milazzo to Lipari, from where it is then possible to connect to the other islands. As connections are not always frequent and perfectly timed, you should plan the whole day for traveling if you plan to connect from Lipari to another island. The Egadi islands can be reached by hydrofoils from Trapani. Sailings take place frequently over the day and the trip takes less than one hour.
Sicily has a good network of motorways and national roads, making it easy and fast to get around. Infrastructure tends to be a bit more remote in the south, center and mountainous areas. Toll is required on the A18 and A20 motorways.

Travelling with children
Travelling in Sicily with children is easy and Sicilians love children. Hotels, restaurants and bars are eager to accommodate families and children. Menus don’t usually serve a dedicated kids menu, but offer smaller or half portions.
Siesta plays an important way of life in Sicily and shops close between 1 and 5pm. Dinner time in Sicily is usually not before 9pm and especially over the summer months kids are out and about until midnight.
Not all activities are suitable for small children, but Sicily has plenty to offer if you are looking for a fulfilling trip for the whole family. Kids will love to explore the cobbled ancient streets of the historic towns, will be fascinated by the volcanic heritage and of course love the outstanding Sicilian food. The sandy beaches in the south are perfect for a couple of relaxing days and farms and agri-tourism accommodation especially cater for families and offer activities centered around nature and the outdoors.

What to bring
If you are travelling to Sicily between May and September, prepare for warm, sunny and dry days, so light summer clothes, light shoes, swimming gear, sun lotion, sunglasses and sun cover should all make it into your luggage. For those heading to Sicily's mountains and volcanoes, steady hiking boots, a headlight/torch, warm jumper and a rain and windproof jacket are advisable. Also mosquitos tend to annoy people over the summer months, so an insect repellent will do no harm. Some of the churches and religious buildings require covered shoulders, so bring a scarf or t-shirt.
While casual leisure wear is totally fine during the day, you should pack a nice outfit for going out in the evenings. There is no dress-code in most bars or restaurants, but clubs might be a different story. Sicilians like to dress to impress at nighttime, so unless you want to stand out, you might want to do the same.
