Island Overview
A wet and unsettled pattern covers Crete on 26 October 2026. Thunderstorms are active over Heraklion, Rethymno, Ierapetra, and Sitia, while lighter rain or showers affect the remaining cities. Temperatures are mild for late October, ranging from 19 to 21°C by day and dropping to 13 to 17°C overnight. UV levels reach moderate despite the cloud cover, peaking at 4.9 in Rethymno, so light sun protection remains relevant during any clear spells.
North vs South
The north coast bears the worst electrical activity in its central stretch. Heraklion expects 7mm of rain with thunderstorms, and Rethymno is similar at 5.5mm. Chania, further west, records only 0.2mm under light rain and is the calmest northern city today. Hersonissos and Malia, in the northeast, have light showers with 2.5 to 2.8mm of rain and temperatures touching 20 to 21°C, the warmest readings on the island today.
On the south and east coast, Ierapetra records the highest winds at 22.9 km/h alongside thunderstorms and 5mm of rain. Makrigialos has only light rain but faces the largest waves of the day at just over 1 metre. Ag. Nikolaos and Elounda, in the sheltered Gulf of Mirabello, see light showers with winds barely above 8 km/h. Sitia, the easternmost city, has the heaviest rainfall today at 8.5mm combined with active thunderstorms.
Mountains and Interior
The White Mountains and Mount Ida will receive heavier rain than the coast and significantly lower temperatures at elevation. Mountain passes will be wet. Check road conditions before driving through the interior or planning a hike. Snow is unlikely but not impossible above 1,800 metres.
Sea, Wind and UV
Sea surface temperatures hold at 22.2 to 22.5°C across the island, a comfortable figure for late October. Winds are light to moderate, with Ierapetra the strongest at 22.9 km/h and the Gulf of Mirabello the calmest at 8.4 km/h. Waves are generally under 0.4 metres except at Ierapetra (0.98m) and Makrigialos (1.02m), where a moderate swell is running. UV peaks at 4.9 in Rethymno; apply SPF during any sunny intervals.
Swim Verdict
The sea is warm at 22°C and would be pleasant in normal conditions. However, active thunderstorms in Heraklion, Rethymno, Ierapetra, and Sitia make it unsafe to enter the water in those areas today. The best option is the Gulf of Mirabello around Ag. Nikolaos and Elounda, where the water is calm and winds are low. Avoid the sea during any electrical activity and wait for full sky clearance before swimming anywhere on the island.
Practical tip: Carry a waterproof layer and plan outdoor activities for the morning, when storm cells are less likely to be fully developed. If you are in Sitia or Ierapetra, where rainfall totals are the highest today, consider postponing beach visits until conditions improve.
