Island Overview
A clean sweep of clear skies covers Crete on 6 September. No precipitation is recorded anywhere on the island. Temperatures range from 28.7°C in Sitia to 33°C in Elounda, placing the island firmly in late-summer heat. The south coast holds overnight lows above 27°C, offering little respite after dark.
North Coast vs South Coast
The northwest is the most comfortable zone today. Chania and Rethymno top out at 30 to 31°C with winds of 14 km/h, well suited to a full beach day. Heraklion reaches 31°C under similar conditions. Moving east along the north shore, Ag. Nikolaos and Elounda push to 33°C with stronger winds around 23 km/h.
The south and southeast runs warmer and stiller. Ierapetra hits 31.6°C but retains a minimum of 27.6°C overnight, the highest floor on the island. Makrigialos reaches 32.5°C. Both areas benefit from near-flat seas, making them well suited to snorkelling and stand-up paddleboarding.
Mountain Areas
Inland areas above 800 metres, including the Lasithi Plateau and the foothills of the White Mountains, will be 5 to 8°C cooler than the coast. Skies are clear at altitude. Conditions are good for hiking, though an early start is advisable before midday heat builds on the lower approach roads.
Sea, Wind, and UV
Sea temperatures sit between 26.3°C at Makrigialos and 27°C at Heraklion. Wave heights are low to very low: the south coast is nearly flat, with Ierapetra at 0.28m and Makrigialos at 0.34m. The north coast sees 0.86m at Hersonissos and Malia, still well within comfortable limits for swimmers. The strongest gusts are in the far east, where Ierapetra reaches 24 km/h and Ag. Nikolaos 23.5 km/h; the northwest is calmer at 14 km/h. UV peaks between 7.25 and 7.55 across the island, firmly in the high band.
Swim Verdict
Conditions are excellent island-wide. Water is warm, clarity is good, and wave action is minimal. The south coast offers the flattest surface today, well suited to families and paddleboard users. On the north shore, light swell at Hersonissos and Malia poses no concern for average swimmers or snorkellers.
Practical Tip for Today
With UV in the high band, unprotected skin can burn in under 25 minutes at midday. Apply SPF 30 or higher before reaching the beach and reapply after each swim. A break from direct sun between noon and 15:00 is the simplest precaution, particularly for children and anyone with fair skin.
