Actual feel will change with wind and rain, but use the suggestions below to build a comfortable layered outfit.

• Thin long sleeves or T-shirts with a light shirt or cardigan are usually enough.
• Dresses, linen shirts, and light pants work well for both comfort and photos.
• Sandals or sneakers are both fine; just choose something you can walk in all day.

• On sunny days, it can feel warm enough that simple T-shirt outfits are very comfortable, especially away from strong sea wind.
• It is an ideal time for scenic drives, terrace cafés, and short beach walks without extreme heat.
• Sea water can feel slightly cool for some swimmers, but the overall atmosphere is perfect for “relaxed, no-stress” trips.

A. Yes, it is one of the easiest months for planning since it avoids both winter cold and peak summer heat and crowds.

Q. Do I need a jacket in March?

A. A light jacket or cardigan is enough for evenings and windy days; many afternoons feel fine with just a shirt or T-shirt.

Q. Is the sea already warm enough to enjoy?

A. For short dips or with a rash guard, yes, but if you want long swim sessions, late spring or summer will feel more comfortable.
