Tinos weather by month runs from cool, wet winters through mild springs to hot, dry summers cooled by the meltemi wind, then warm, calm autumns. Daytime highs climb from about 15°C in January to 27–30°C in August, and the sea is warmest from July to October. This guide breaks the climate down month by month to help you plan a trip.
Understanding the year’s pattern helps you pick the right time to go, a choice set out in full in the guide to the best time to visit Tinos. The island’s weather is classic Cycladic, with one famous quirk. The sections below cover the seasons in detail.
What is the climate like overall?
The climate is Mediterranean, with hot, dry summers and mild, wetter winters, and it is windy year-round. Rain falls mostly from November to March, summers stay almost rainless, and the meltemi wind cools the hottest months from the north.
The island follows the classic Cycladic pattern with one twist. Summers are hot, arid and clear, winters are cool, damp and partly cloudy, and the wind blows in every season. Rain concentrates in the November-to-March window, while June to September stays almost dry. The defining feature is the meltemi, a strong north wind that sweeps the Aegean in July and August, cooling the heat but whipping up the sea and the exposed beaches. This wind shapes how the summer feels. The year divides into four clear seasons.
What is spring like, March to May?
Spring is mild and green, warming from about 16°C in March to 21°C in May, with the last of the rain easing and the wildflowers out. It is calm, quiet and pleasant for walking, though the sea is still cool for swimming.
Spring is one of the loveliest times on the island. March stays cool at around 16°C with occasional showers, but by April and May the days warm into the high teens and low twenties, the hillsides turn green and the wildflowers bloom. The meltemi has not yet arrived, so the air is calm, and the villages are quiet before the summer crowds. The sea remains cool for swimming until late spring, but the walking and sightseeing are at their best. The season suits hikers and early visitors. Summer brings the heat and the wind.
What is summer like, June to September?
Summer is hot and dry, with highs of 27–30°C in July and August and warm, swimmable seas. The meltemi wind peaks in these months, cooling the heat but ruffling the exposed beaches, so sheltered coves are favoured on windy days.
Summer is the peak season, busy and bright. July and August bring highs of 27 to 30°C, near-zero rainfall and long sunny days, with the sea warm enough for easy swimming. The meltemi wind is strongest now, a blessing that tempers the heat but a challenge on the north-facing beaches, which is why sheltered south- and west-coast coves fill on windy days. June and September are gentler, still warm and swimmable but calmer and less crowded. The August 15 pilgrimage packs the island at the season’s height. Autumn keeps the warmth a while longer.
What is autumn and winter like?
Autumn stays warm into October, around 22–24°C with the sea at its warmest and the wind dropping, then cools through November as the rains return. Winter is cool and wet, with January the coldest at about 15°C and the wettest month of the year.
The year winds down gently before turning wet. October is a fine month, warm at 22 to 24°C, with the sea at its warmest after a summer of heating and the meltemi finally fading, ideal for a quieter beach trip. November cools and the rains return, and from December to February the island is cool and damp, with January the coldest at around 15°C by day and the wettest month, near 83 mm of rain. The villages turn quiet and many tourist businesses close. The best months sit at the year’s two shoulders, as the guide to the best time to visit Tinos sets out. The questions below cover the points travellers ask most.
