Additional Information

Weather –The northwestern part of Slovenia has an Alpine climate and temperatures in the valleys are moderate. June through September are the prime visiting months. The Adriatic coast enjoys a Mediterranean climate (warm sunny days). Temperatures in these regions in this time of the year  (April) typically range from the lower 50s to the upper 60s.

Dress code – Slovenians tend to dress somewhat more smartly than Americans, although more casual clothes are acceptable. Jeans, lighter weight pants, t-shirts or camisoles, and sundresses are popular options for casual wear. Lightweight jackets or sweaters are advisable for occasional cooler evenings. Slovenians generally walk more than Americans so comfortable walking footwear is advisable. Trips involving running, cycling, hiking, water sport or other outdoor activities will require specialist gear.

Slovenia is a member of the European Union and more than half of the population declares to be Roman Catholics. There are no discernible religious customs that would influence tourists’ dress code, though street clothes (rather than swimsuits) and sometimes over-the-knee pants and shirts are required in churches, museums and other institutions.

Security – Slovenia is generally a very safe country. Still, pickpockets operate everywhere so avoid leaving your belongings unattended and avoid carrying large sums of cash or valuables with you on daytrips. Women can walk alone in virtually all areas and cities even at night.
