Timing your visit to Preveza can make the difference between a good boating holiday and an unforgettable one. The Ionian Sea enjoys a long season of warm weather and calm waters, but each month brings its own character. Here is your complete guide to choosing the best time to visit Preveza for boating and cruises.
The Boating Season in Preveza: Overview
The boating season in Preveza typically runs from May through October, with the peak months being June through September. Outside this window, cooler temperatures and stronger winds make recreational boating less enjoyable for most visitors.
Here is a month-by-month breakdown to help you plan your boat rental or private cruise.
May: The Quiet Start
Water temperature: 18-20 degrees C
Air temperature: 20-25 degrees C
Crowds: Very low
May is when the season begins. The weather is warm and pleasant, the sea is calm, and the islands are virtually empty. Water temperature is still cool for swimming but manageable. May is ideal for those who want to explore without any crowds – you will have beaches like Porto Katsiki and Egremni almost entirely to yourself.
June: The Sweet Spot
Water temperature: 22-24 degrees C
Air temperature: 25-30 degrees C
Crowds: Low to moderate
June is arguably the best month for boating in Preveza. The water is warm enough for comfortable swimming, the days are long (sunset after 20:30), and the summer crowds have not yet arrived. Winds are generally light, making it perfect for trips to Paxos and Antipaxos or Meganisi.
July: Peak Summer Begins
Water temperature: 24-26 degrees C
Air temperature: 28-33 degrees C
Crowds: Moderate to high
July brings full summer heat and the warmest swimming conditions. The Ionian Sea is at its most inviting – perfect turquoise colors and excellent visibility for snorkeling. Afternoon breezes (the meltemi) can pick up, so morning departures are recommended for longer trips.
This is high season, so booking in advance is strongly recommended.
August: The Busiest Month
Water temperature: 25-27 degrees C
Air temperature: 29-35 degrees C
Crowds: High
August is the peak of Greek summer tourism. The water is at its warmest, the weather is reliably sunny, and the atmosphere is vibrant. Popular beaches will be busier, but with a private boat cruise, you can always find secluded spots away from the crowds.
Book well in advance for August – both boats and accommodation fill up quickly.
September: The Golden Month
Water temperature: 24-26 degrees C
Air temperature: 25-30 degrees C
Crowds: Low to moderate
September is many locals favorite month. The summer crowds have thinned, the sea is still wonderfully warm, and the light takes on a golden quality that makes everything look even more beautiful. Winds tend to calm down, creating ideal conditions for island hopping.

October: The Peaceful Finale
Water temperature: 21-23 degrees C
Air temperature: 20-25 degrees C
Crowds: Very low
October still offers plenty of good boating days, though the weather becomes less predictable. On calm days, the sea is beautiful and the water is still swimmable. By late October, the season winds down and many seasonal businesses close.

Weather and Wind Conditions
The Ionian Sea is generally calmer than the Aegean, which is one of the reasons Preveza is such a great base for boating. However, afternoon northwesterly winds can develop in July and August. For the calmest conditions:
- Depart early in the morning (before 10:00)
- The east coasts of islands are more sheltered from prevailing winds
- June and September typically have the calmest seas
- Always check the forecast before heading out – your skipper or our team can advise
