Late March Weather for Sicily

Not at all, weather will be cooler but layer 7pmand be prepared for poss rain with proper shoes and rain gear in case. Sicily will be wonderful, we were there in summer and the heat was intense. Fortunately we had ac in transport and at hotels.

You can take a look at actual, day-by-day historical weather at various locations in Sicily on the website timeanddate.com. I've linked to Palermo's stats for March 2019, but I'd check at least the most recent three years; five would be better. The Wikipedia page for Palermo shows an average of just under 9 days and 3 inches of rain in March.

No, you wouldn't be crazy. Not very much rain when we went-your trip might be different. Here's the reply I posted on your other Sicily tour question:

Hi Luv2. You are going to love your time in Sicily! We took this tour twice. In late March we found the weather less rainy than the previous tour in late February but still had a little rain from time to time. It was jacket or layers, cool at night and pleasant weather during most days. During the March tour, we had the added bonus of being there during Easter Week and what a treat that was for us! We enjoyed every second of the week long celebration.

Thank you all for the info! Crossing fingers we’re truly going to go.

We traveled to Sicily at that exact time. It often became a little cool at night, but the days were typically very pleasant. I was very glad we were not there in the heat of summer.
