Weather in Zakynthos

Weather — Zakynthos Island, Greece

Zakynthos enjoys a typical Ionian / Mediterranean climate: mild, wet winters and warm, very sunny summers. Average daytime highs range from about 14 °C in winter to around 26 °C at the peak of summer, while rainfall is concentrated in late autumn and winter (especially November–December). If you’re planning a trip for beaches and swimming, aim for May–September; for cheaper fares and gentler weather choose April or October.

Weather — Zakynthos Island January

January is mild but one of the wettest winter months: expect average highs near 14 °C and lows around 12 °C, roughly 146 mm of precipitation across about 18 rainy days and only a few truly sunny days. Windy spells (avg ~24 km/h) make evenings feel cooler — pack a warm layer and a waterproof jacket.

Weather — Zakynthos Island February

February stays cool with average highs about 13–16 °C and around 101 mm of rain spread over roughly 16 days. Like January, it’s changeable: some bright, mild days alternate with rainy, blustery periods — good for off-season sightseeing but not for beach weather.

Weather — Zakynthos Island March

March signals a shift toward spring: daytime temperatures average around 14–17 °C, precipitation drops to roughly 78 mm, and sunny days increase. It’s a pleasant month for walking the island and avoiding crowds, though sea swimming will still feel chilly for most people.

Weather — Zakynthos Island April

April is an attractive shoulder month with average highs near 16–19 °C, lower rainfall (about 35 mm) and more sunshine. Days are comfortably warm for exploring beaches and villages; evenings can be cool, so bring a light jacket.

Weather — Zakynthos Island May

May is when Zakynthos really begins to feel like summer: average highs around 19–22 °C, very little rain (≈18 mm) and roughly 13 sunny days. Sea temperatures are rising and many travelers find May ideal — warm enough for swimming and outdoor activities without peak-season crowds.

Weather — Zakynthos Island June

June brings reliably warm, dry weather with average highs around 23–26 °C, only about 10 mm of rain and long sunny days (≈21 sunny days). Light sea breezes (avg ~17 km/h) keep conditions pleasant; perfect for beach holidays and boat trips.

Weather — Zakynthos Island July

July is high summer: daily highs average about 25–27 °C with almost no rain and up to 29 sunny days. It’s hot, bright and ideal for sunbathing, swimming and island nightlife — expect busy beaches and peak-season prices.

Weather — Zakynthos Island August

August is typically the warmest month, with average highs around 26–28 °C and minimal rainfall. Long, hot, sunny days dominate and sea conditions are at their best for swimming and diving. Book accommodations and flights early if you plan to travel in August.

Weather — Zakynthos Island September

September still offers late-summer warmth (avg highs around 24–26 °C) but rainfall begins to increase (≈65 mm). It’s a great compromise: warm sea temperatures and fewer tourists than July–August, though occasional autumn storms become more likely toward the end of the month.

Weather — Zakynthos Island October

October cools down to average highs of about 21–24 °C and sees a marked increase in precipitation (around 113 mm). Early October can still be pleasant for sightseeing and late-season beaches, but expect more rainy days and windier conditions as autumn sets in.

November is the wettest month on Zakynthos with roughly 179 mm of rain over about 16 days; average highs sit near 19–21 °C. It’s a quiet time for tourism — good for lower prices and off-peak travel if you don’t mind occasional storms and cooler, windier weather.

Weather — Zakynthos Island December

December brings mild winter temperatures (average highs around 15–18 °C) but significant rainfall (about 163 mm) and only a few sunny days. Outdoor activities remain possible on dry days but pack for wet, breezy conditions.
