Scenery & character
Greece wins on raw drama. The Cyclades — whitewashed villages perched on volcanic caldera, windmills on headlands, the approach to Santorini's caldera by sea — are among the most iconic images in world travel. The Ionian Islands are lush, green, and beautiful in a softer way. Greek culture, history, and food are extraordinary; every anchorage has a story 3,000 years old.
Croatia has a different beauty — the Dalmatian Coast's combination of medieval walled cities (Dubrovnik, Korčula, Trogir), pine-forested islands, and emerald Adriatic water is genuinely stunning. Less dramatic than Greece but more consistently photogenic. The food — fresh seafood, local wine, truffles in Istria — is exceptional.
Sailing conditions
Greece is defined by the meltemi — a dry northerly that builds in the Aegean each afternoon in July and August, typically reaching force 4–6, occasionally more. It makes for exhilarating sailing and provides reliable downwind runs between islands. In the Ionian (Greece's western coast), conditions are much lighter and more suitable for beginners.
Croatia has the maestral — a reliable afternoon sea breeze of force 3–4 that provides consistent, non-threatening sailing. The Adriatic is more sheltered than the Aegean; passages are shorter (rarely more than 25nm between stops) and the anchorages are better protected. Croatia is significantly easier sailing, particularly for beginners and families.

Difficulty
For beginners: Croatia wins decisively. The Dalmatian Coast's sheltered waters, short passages, and reliable maestral make it the Mediterranean's most forgiving first-charter destination. The Ionian Islands in Greece are a close second. Avoid the Cyclades for your first charter.
For experienced sailors: Greece offers more variety and challenge. The Cyclades in summer deliver serious sailing — the meltemi tests boat handling, anchorage selection, and passage planning. More rewarding for sailors who want to earn their anchorages.
Cost
Both are broadly comparable. Croatia is marginally cheaper — marina fees and provisioning are slightly lower, and the anchorage permit system (NCI) costs $11–$28/night in many bays. Greece is more expensive in peak season (July/August) particularly in popular Cycladic ports. Turkey is significantly cheaper than both.
Best time to go
Greece: May, June, September. July/August in the Cyclades is for experienced sailors comfortable with the meltemi; the Ionian is suitable year-round in the sailing season.
Croatia: May, June, September. July/August is busy but the maestral makes sailing reliable. September is arguably the best month — warm water, quieter anchorages, excellent prices.
The verdict
Choose Greece if: you're an experienced sailor who wants dramatic scenery and challenging conditions, you've always dreamed of Santorini and Mykonos by sea, or you want the Mediterranean's greatest cultural sailing experience.
Choose Croatia if: this is your first charter or you're sailing with beginners/families, you want guaranteed easy conditions, you prefer lush green islands and medieval harbours over stark volcanic drama, or you want the best value for money in the Mediterranean.
