Bulletin du jour en vidéo

A grey but dry Wednesday across Crete. High cloud and overcast skies cover most of the island, with Heraklion the only city reporting fog this morning. No rain is forecast anywhere, and daytime highs sit in the 21 to 24°C range, which is comfortable and typical for late October.

North Coast vs South Coast

The north coast wakes up cool. Heraklion recorded a low of 10.6°C overnight, and morning fog is expected to thin gradually as temperatures climb toward an afternoon high of 22.5°C. Chania and Rethymno are overcast with morning readings around 13 to 14°C and afternoon peaks near 23°C. Winds along the north coast stay below 11 km/h throughout the day, making it feel still and mild once the fog clears.

The south coast runs noticeably warmer. Ierapetra reaches 23.8°C with a low of 17.6°C, barely feeling like autumn. Makrigialos matches the 23.8°C high with a minimum of 16.4°C. This corner of the island consistently ranks among the warmest coastal areas in Europe in late October, and today holds to that pattern.

Mountain Conditions

The White Mountains above Chania and the Psiloritis massif will be significantly colder than the coast, with temperatures likely below 10°C above 1,500 metres. Anyone heading into upland gorges or the Omalos plateau should carry a warm mid-layer regardless of how mild it feels at sea level.

Sea State, Wind and UV

Winds are light across the island, from 6.8 km/h in Chania up to 12.3 km/h in Ierapetra. All coastal conditions are flat to calm, with maximum wave heights ranging from 0.08 m off the northwest to 0.22 m near Sitia in the east. Sea temperatures are holding at 22.3 to 23.0°C, above the European average for October swimming. The UV index peaks at around 5 across all areas, which is moderate. Sunscreen is still worth applying if the overcast breaks in the afternoon.

Swim Verdict

Conditions support swimming today. Water temperatures of 22 to 23°C are genuinely comfortable, and wave action is negligible everywhere. The overcast sky reduces direct sun exposure but has no effect on the warmth of the water. The south coast beaches at Ierapetra and Makrigialos offer the calmest seas and the warmest sea temperatures on the island today.

Practical Tip for the Day

Pack a light jacket for the morning, particularly in Heraklion where fog makes the air feel damp and cooler than the thermometer alone suggests. By midday, temperatures recover into the low twenties across all areas and a single layer will be enough. No adjustments are needed for rain today.
