Greece isn’t facing one nationwide drought this summer. A cluster of small Aegean islands has declared water emergencies, while Athens and the rest of the mainland carry on close to normal.
Astypalaia is the clearest example: its main reservoir has dropped to about a sixth of capacity. If a Greece drought headline has you worried about an upcoming trip, the honest answer depends entirely on which part of the country you’re actually visiting.
- A handful of Aegean islands, Astypalaia chief among them, have declared water emergencies in 2026.
- Athens and the wider Greek mainland are unaffected.
- Astypalaia’s reservoir sits at roughly a sixth of capacity, with about 5.5 months of water left at current use.
- Water-saving requests, like skipping housekeeping, are common on islands under a water emergency.
Which parts of Greece actually have a water problem
Seven islands across the Aegean have declared drought emergencies in 2026, the result of an unusually erratic run of rainfall landing on top of a packed tourist season.
Patmos
Symi
Karpathos
Leros
Poros
Astypalaia, a quiet Dodecanese island known for its castle and its beaches, is the most documented case. Its main reservoir, which supplies both the capital Chora and the farming village of Livadi, has fallen to around 150,000 cubic metres, about a sixth of what it’s built to hold.
Local mayor Nikos Komineas summed up how little rain the island sees in an average year. “If we collected all the water dropped throughout the year in a bucket or in a washbowl, it would be 2.5 centimetres deep,” he said.
Astypalaia isn’t the only island in this position. Patmos and Symi have also declared emergencies this year.
So have Karpathos and Leros. Aegina, out in the Saronic Gulf, joined the list too, even though it sits much closer to Athens than the others.
Poros, also in the Saronic Gulf, became the newest addition in mid-July, and the tally keeps climbing as the dry summer wears on.
Farmers have felt it first. Growers in Livadi were cut off from irrigation water back in April to protect what’s left in the reservoir for drinking water over summer.
Crete, Greece’s largest island, is dealing with a longer dry stretch of its own: its fourth consecutive dry hydrological year. That’s a slow-moving water-management problem, not a holiday-disrupting one, and no rationing has been announced there.
What this means if you’re travelling to Greece now
Heading to the mainland or one of the bigger, popular Cycladic islands? Nothing in this drought story changes your itinerary.
Heading to Astypalaia, Patmos or one of the other affected islands? Expect lower water pressure at times, and don’t be surprised if your accommodation asks you to skip a day of housekeeping.
One hotelier on Astypalaia now offers guests a five euro voucher for skipping daily room cleaning. Little gestures like that are becoming common on islands with a declared water emergency.
A reusable water bottle is worth packing regardless of where you land in Greece this summer. On the islands hit hardest, bottled water and refill points are the norm, so treat every tap with a bit more care than usual.
Private pools attached to villas and holiday rentals face the tightest restrictions, since a recent boom in pool construction is straining reserves on some islands. Ask your host directly before booking if this matters to your trip.
The government has backed that up with real money rather than warnings alone.
Greece’s environment minister approved about €15 million ($17 million) to fund desalination units and grid upgrades on nine of the country’s more than 200 inhabited islands, with water tankers sent where needed most.
Wildfire risk and the summer heat picture
Dry ground and an ongoing summer heatwave raise wildfire risk too, and 2026 has already brought blazes near Thessaloniki and parts of central Greece.
None of this is a reason to cancel a trip outright. It’s worth a quick read of our Greece wildfires update alongside our Greece heatwave guide before you fly, just so you know what to check once you arrive.
Frequently Asked Questions
Is it safe to travel to Greece during the 2026 drought?
Yes, for almost every destination. The water emergencies are limited to a handful of Aegean islands, while the capital and the wider mainland are operating as usual.
Which Greek islands have declared a water emergency in 2026?
Astypalaia and Patmos are among them, along with Symi and Karpathos. Leros and Aegina have too, and the complete list has grown to seven islands out of more than 200 inhabited ones nationwide.
Will there be water shortages for tourists in Greece?
Only on the islands under a water emergency, and mostly as lower pressure or a request to cut back on housekeeping rather than an outright shortage. Being mindful of it means you’ll barely notice the difference.
Does the Greece water crisis reach Santorini or Mykonos?
No. The islands under emergency status are smaller and less visited than the well-known Cycladic favourites, so a trip to the bigger tourist islands is spared.
How long will Astypalaia’s water shortage last?
Officials estimate the current reservoir should hold for about 5.5 months at summer consumption rates. A temporary desalination plant is already running, and a permanent one is due by the end of 2026.
Planning your trip
None of this news should stop you booking a Greek getaway this year. Search Wego for fares and stays, then check the specific island’s water situation once you know where you’re headed.
Pack that reusable bottle either way. It’s a modest habit that helps wherever you go.
