Island Overview
A blanket of cloud and fog covers Crete on 25 October 2026. Every reporting station logs overcast or foggy conditions, with no clear skies anywhere on the island. Temperatures sit in a narrow band between 21 and 23°C at the peak of the afternoon, making this a comfortable but grey late-October day. Rainfall is negligible: Ierapetra records just 0.6 mm, Heraklion a trace of 0.1 mm, and all other locations stay completely dry.
North and South Coast
The north coast from Chania to Hersonissos is uniformly overcast with light to moderate winds. Chania stands out with the gentlest breeze on the island at 7 km/h, while Rethymno sees the strongest gusts at 20 km/h, worth noting for anyone planning a cycle ride or long walk exposed to the sea. Morning lows along the north stay cooler than the south, with Heraklion dropping to 13.8°C overnight, the coldest reading island-wide.
The south and east coast towns hold warmer overnight temperatures. Malia and Ierapetra both stay above 18°C at their minimums, and Makrigialos holds at 17°C. Fog rather than heavy cloud covers parts of the far east, including Sitia and Makrigialos, which may thin through the late morning, though a full clear to sunshine is not guaranteed today.
Mountains
The White Mountains above Chania and the Psiloritis massif above Rethymno are likely shrouded in low cloud given the overcast conditions at sea level. Temperatures at 1,500 m will run several degrees below the coast. Hikers heading into the gorges or upland paths should carry an extra layer and check trail conditions locally before setting out.
Sea, Wind and UV
The sea is in excellent shape for late October. Surface temperatures hold between 22.2 and 22.6°C across all coasts, and wave heights are minimal, ranging from 0.14 m at Agios Nikolaos to 0.40 m at Chania and Ierapetra. Winds are light to moderate island-wide, with only Rethymno approaching 20 km/h. The UV index sits in the moderate range between 3.9 and 4.75: cloud cover reduces exposure but does not eliminate it, so sunscreen remains relevant for extended time outdoors.
Swim Verdict
Conditions are good for swimming at most beaches. The water is calm and warm for the time of year, and winds are not a concern except at Rethymno. The overcast and foggy sky may make the air feel cooler than the sea temperature suggests, so a light cover-up for when you leave the water is worth packing.
Practical Tip for the Day
Pack a light jacket for the evening. Overnight lows, particularly in Heraklion at 13.8°C, signal a cool night ahead. Cloud cover means the afternoon warmth fades quickly after sunset, and the temperature drop is faster than on a clear October day. A mid-layer over a t-shirt handles the swing from afternoon to evening without needing a full coat.
