Island Overview
Clear skies and zero rainfall define Crete on 17 July 2026. Temperatures span from 28.7°C in Rethymno to 32.3°C at Agios Nikolaos and Elounda. Every coastal station is in unbroken sunshine today, and that will remain the case throughout the day.
North Coast vs South Coast
The north coast from Chania (29.9°C) through Heraklion (30.2°C) to Hersonissos (28.9°C) is warm and relatively settled, with winds sitting between 15 and 27 km/h. The south and east tell a different story. Ierapetra tops out at 30.8°C with gusts reaching 43.6 km/h, the strongest reading across the island today. Makrigialos records 31.5°C with 34.3 km/h gusts, and Agios Nikolaos together with Elounda combine the day's highest temperatures at 32.3°C with 32.8 km/h winds. The meltemi is pushing through the eastern half of the island with real force.
Mountain Conditions
The White Mountains above Chania and the Psiloritis massif above Rethymno offer meaningful relief from coastal heat. At altitude, temperatures run 15 to 20°C cooler than at sea level. Trails are dry and in good condition. UV remains significant even at elevation, so sunscreen is not optional on any mountain walk today.
Sea State, Wind and UV
Sea temperatures across the island range from 24.8°C at Makrigialos to 26.8°C off Rethymno, with most north coast locations sitting between 25.7 and 26.8°C. Wave heights on the north and east coasts run between 1.0 and 1.3 metres, which is moderate and manageable for most swimmers. The south coast at Ierapetra is near-flat at 0.4 m because the dominant northerly wind blows from the mountains outward to sea, generating no inbound swell. UV peaks between 8.25 and 8.55 at all stations. The WHO classifies anything above 8 as very high: unprotected skin can burn in under 20 minutes at midday.
Swim Verdict
The north coast is the clear best option for a beach day today. Chania, Rethymno, Heraklion, Hersonissos and Malia all offer warm water, moderate surf and reasonable breezes. The east coast bays at Agios Nikolaos and Elounda are swimmable but expect sustained gusts on the beach itself. The south coast at Ierapetra and Makrigialos is very windy despite a calm sea; beach umbrellas and loungers will not stay in place without weights. If you want a relaxed afternoon in the water, the north coast wins today.
Practical Tip for the Day
A UV index of 8 or above causes real skin damage faster than most people expect. Apply SPF 50 before leaving accommodation, reapply after every swim, and plan shade or indoor time between 12:00 and 15:00. If you are driving across to the south coast, note that gusts can sustain above 40 km/h through the afternoon on exposed stretches. Pack a light layer for the return journey once the sun drops.
