Forecasters say Tuesday is the most likely day for widespread rain and thunderstorms, while reservoir levels are nearly three times higher than a year ago.

A three-day spell of unstable weather is expected to affect Cyprus from Monday, with meteorologists warning that Tuesday is the most likely day for widespread and intense weather conditions.

Meteorological officer Tasos Koulentis told CNA that Monday, Tuesday and Wednesday are expected to be marked by atmospheric instability, with cloud build-up developing through the day and leading to local showers and thunderstorms.

Rain or isolated thunderstorms are also possible overnight, particularly in coastal areas.

Tuesday under close watch

Koulentis said Tuesday currently appears to be the day with the highest likelihood of extensive and intense weather activity.

However, he added that authorities are awaiting updated forecast data before deciding whether to issue any weather warnings.

Conditions are expected to improve on Thursday and Friday, when the weather will be mainly fine with periods of increased cloud cover.

Temperatures are forecast to rise gradually through the week but are expected to remain slightly below seasonal averages.

Reservoir levels far higher than last year

At the same time, Cyprus' reservoir network is in a significantly stronger position than it was a year ago.

According to the Water Development Department, dam capacity currently stands at 35.8%, compared with 12.3% at the same time last year.

By 2 October, the island's reservoirs were holding a total of 103.975 million cubic metres of water, compared with 35.688 million cubic metres during the corresponding period of 2025.

Largest reservoirs

Current levels include:

  • Kouris Dam: 42.882 million cubic metres (37.3%)
  • Asprokremmos Dam: 18.897 million cubic metres (36.1%)
  • Evretou Dam: 9.344 million cubic metres (38.9%)
  • Kannaviou Dam: 7.301 million cubic metres (42.5%)
  • Germasogeia Dam: 6.579 million cubic metres (48.7%)

A year earlier, the same reservoirs held substantially lower volumes, with most recording filling rates close to or below 13%.

The latest figures highlight a significant improvement in Cyprus' water reserves heading into the winter season.
