Sailing conditions in Greece are as diverse as the regions themselves, making it a destination suitable for all levels of experience from relaxed family cruising to more challenging passages for seasoned sailors.

General Weather and Seasons

Greece enjoys a long sailing season from April through October, with warm temperatures, blue skies and reliable winds. July and August are the hottest and busiest months, with average daytime temperatures in the high 20s to mid-30s °C. Shoulder months like May, June, September and early October offer excellent conditions with fewer crowds.

Winds and Regional Variations

The dominant summer wind in Greece is the Meltemi, a strong northerly that affects much of the Aegean, particularly from mid-June through August. While it brings clear skies and good visibility, it can also produce gusty conditions and rough seas, especially in open passages between islands. Here’s what to expect by region:

• Ionian Sea: Sheltered and calm, we've always considered the Ionian ideal for beginners or relaxed sailing. Winds are typically light to moderate, blowing from the northwest in the afternoon and dying down overnight.
• Cyclades: Here you will experience stronger Meltemi winds, especially in July and August. While this offers thrilling sailing for experienced charter groups, it may be too challenging for first-time charterers. Protection can be limited in some anchorages.

• Saronic Gulf: More protected from the Meltemi, the Saronic offers consistent and manageable winds, typically Force 3–5 from the northeast. It's a good middle ground for a moderate sailing experience.
• Dodecanese: The Meltemi also reaches this area but tends to be more predictable. Winds are moderate and steady, ideal for confident sailors who enjoy longer passages with cultural stops.
• Sporades: Winds here are generally milder and more consistent than the Cyclades. Expect north to northwest breezes, making it a comfortable cruising ground with lush scenery and well-spaced islands.
• Southern Peloponnese: This area has varied conditions, often influenced by local terrain. Summer winds are generally reliable from the northwest, with calmer nights. It’s a quieter alternative for more confident sailors.

Sea Conditions

Sea state in Greece is mostly moderate, although the Aegean can get choppy during Meltemi spells. Open crossings, like those between Cyclades islands, can become uncomfortable in high winds. The Ionian and Saronic seas are typically smoother, with less swell and more sheltered bays.

Tides and Navigation

Greece has minimal tidal variation of usually less than half a metre, which certainly simplifies anchoring and mooring. Navigation is straightforward, although attention is needed for rocks, ferries in busy channels and potentially tight manoeuvring in marinas.
