Island Overview
Crete on 22 August 2026 is running a clean sweep: every reporting station from Chania to Sitia records clear sky and zero precipitation. Daytime highs range narrowly from 30.7°C in Ierapetra to 32.6°C in Elounda, which means there is no meaningful cooler corner to retreat to. This is a standard late-August Aegean day in full effect across all four prefectures.
North Coast vs South Coast
The north coast carries more wind today. Heraklion leads at 20.6 km/h, a moderate meltemi that puts spray on the sea and makes afternoon sun tolerable on the promenade. Hersonissos and Malia share 15 km/h, and Chania and Rethymno sit just below at 13 to 14 km/h. That consistent airflow across the north also keeps overnight temperatures honest: Heraklion drops to 18.2°C, giving residents and visitors a genuine cool-down after dark.
The south and east are noticeably calmer. Ag. Nikolaos and Elounda record only 10.6 km/h, and the south-coast towns of Ierapetra and Makrigialos hover around 11 to 12 km/h. The trade-off is warmer nights: Ierapetra holds at 25.3°C through the night and Makrigialos at 25.0°C, so air conditioning earns its keep on that stretch of coast.
Mountains
The White Mountains above Chania and the Psiloritis massif above Rethymno are dry and fully clear today. Hikers on the Samaria trail or the E4 route will have unobstructed visibility. Temperatures drop sharply with altitude; carry a wind layer above 1,000 metres, especially if you plan to be on the ridge past mid-afternoon when the breeze picks up.
Sea, Wind and UV
Sea surface temperatures range from 26.0°C off Sitia to 27.0°C at Heraklion, all of it well above the comfortable threshold for extended swimming. Wave heights are low everywhere: the largest reading is 0.78 metres off Chania; Rethymno and Ag. Nikolaos sit at just 0.34 metres. UV index peaks between 7.7 and 7.9 across all stations, which places every location in the high category. SPF 30 minimum, reapplication after every swim, and shade between 11:00 and 15:00 are not suggestions at this level.
Swim Verdict
Green light island-wide. Warm water, calm to light seas, and negligible swell make today one of the better beach days of the summer. The north coast carries slightly more surface chop than the south due to the meltemi, but nothing that affects safety or comfort in the water. All coasts are suitable for swimmers of all levels.
Practical Tip for the Day
Hit the beach before 10:00, take a genuine break between 11:30 and 15:30, then return to the water for the late afternoon. The south-coast beaches around Makrigialos and Ierapetra are particularly good for this rhythm: the wind stays light all day, the afternoon light is excellent, and the sea holds warmth well into the evening.
