Weather in Greece in May
May is a delightful month to visit Greece: it bridges spring and summer, offering warm sunshine, blooming landscapes, and increasingly pleasant sea conditions. Whether you’re heading to the islands or exploring the mainland, understanding what the weather brings can help you plan wisely. This article covers average temperatures, rainfall, regional patterns, sea conditions, and travel tips for weather in Greece in May.
General Climate Patterns in May
In May, Greece transitions from spring into early summer. The days grow longer and warmer, and rainfall generally decreases compared to earlier spring months.
- Daytime highs across much of Greece tend to fall between 20 °C and 25 °C (68 °F to 77 °F).
- Nights remain mild, often hovering around 12 °C to 16 °C (54 °F to 61 °F).
- Sunshine is abundant, though occasional spring showers or isolated thunderstorms are still possible, especially in the northern mainland or mountainous areas.
- Humidity is moderate; sea breezes help moderate coastal heat.
Thus, when considering temp in Greece in May, you’ll find it comfortably warm without the intense heat of summer months like July or August.
Temperature in Rhodes in May
Rhodes, one of the southeastern Aegean islands, enjoys one of the warmer climates in Greece.
Daytime and Nighttime Temperatures
- Average high in Rhodes in May often reaches 24 °C to 26 °C (75 °F to 79 °F).
- Overnight lows generally stay around 14 °C to 16 °C (57 °F to 61 °F).
- As May progresses, daytime highs may climb further toward the upper 20s.
Rain and Sunshine
- Rain is rare in May; Rhodes typically sees fewer rainy days than in earlier spring months.
- Sunshine is strong, with many clear, bright days making it ideal for beach and outdoor activities.
Thus, when planning for temp in Rhodes in May, expect pleasantly warm days and mild evenings — perfect for sightseeing and sea swimming.
Temperature in Crete in May
Crete, Greece’s largest island, spans varied terrain. Weather can slightly vary from coast to interior, but here’s the general picture for temp in Crete in May.
Coastal Conditions
- Daytime highs along coastal Crete often reach 22 °C to 25 °C (72 °F to 77 °F).
- Nighttime lows rest around 13 °C to 15 °C (55 °F to 59 °F).
- The southern coast tends to be slightly warmer and drier.
Inland and Elevated Areas
- In hilly or mountainous interior parts of Crete, nights may be cooler, dipping slightly below coastal figures.
- Daytime highs inland may not differ drastically but could be slightly lower on cloudy days.
Rain and Winds
- Rain in May is modest; occasional showers might occur, more so in western parts of Crete.
- Winds are generally mild; occasional breezes help mild the warmth.
All told, temp in Crete in May is comfortably warm, especially for travelers who prefer moderate heat ahead of the hot summer.
Corfu in May Weather
Corfu, off Greece’s western coast, experiences a different pattern compared with the Aegean and southern islands. Let’s examine Corfu in May weather.
Temperature Ranges
- Daytime highs typically run 20 °C to 22 °C (68 °F to 72 °F).
- Nighttime lows can drop to about 11 °C to 14 °C (52 °F to 57 °F).
- As May advances, the sea and air warm, making afternoons pleasantly toasty.
Rainfall and Variability
- Western Greece, including Corfu, gets more Atlantic-influenced moisture. Rainfall in May is not heavy but more likely than in more southerly islands.
- Rainy days are possible, usually as brief showers or light thunderstorms rather than prolonged storms.
- Cloud cover may appear occasionally but many clear days dominate.
Sunshine and Wind
- Good sunshine periods prevail, though some days may be mixed with clouds.
- Sea breezes help moderate daytime warmth, especially closer to the coast.
Hence, Corfu in May weather is mild and enjoyable — though packing a light rain jacket and layers is wise.
Regional Comparisons and Contrasts
It’s useful to compare weather across regions to see how conditions differ from island to island and between coasts.
| Region / Island | Avg High (°C) May | Avg Low (°C) May | Rain Likelihood | Notes |
|---|---|---|---|---|
| Rhodes | 24–26 | 14–16 | Low | Very sunny, warmest among many islands |
| Crete (coast) | 22–25 | 13–15 | Low to moderate | Interior areas slightly cooler |
| Corfu | 20–22 | 11–14 | Moderate | More rainfall risk, more variable |
| Mainland Northern Greece | 18–22 | 10–13 | Moderate | Possible spring showers |
As you can see, southern and southeastern islands (Rhodes, Crete) tend to be warmer and drier than western islands like Corfu or northern mainland zones.
Sea Conditions and Swimming
One of the attractions of visiting Greece in May is entering the water before the summer rush. Here’s what to expect:
- Sea temperatures in many islands by late May are often 19 °C to 21 °C (66 °F to 70 °F).
- In the southern Aegean (e.g. around Rhodes) the sea warms faster, so earlier swimming is more comfortable.
- The sea is generally calm, and with sunshine, even moderate swimmers will find water enticing.
- However, early in May, swimming might feel a bit brisk, especially in more northerly or shaded coves.
Thus for many, May represents the start of Greece’s comfortable swim season — perhaps not tropical warm, but refreshing.
Rainfall and Sunshine Hours
- Rain in May is typically modest across Greece. Coastal and island areas see fewer rainy days than in winter or early spring.
- Sunshine hours per day often reach 8 to 10 hours, sometimes more on clear days.
- Rain showers, when they occur, tend to be brief rather than prolonged.
- Thunderstorms are possible but less common than in transitional spring months.
So for planning purposes, weather risk in May is relatively low compared to earlier in the year.
What to Pack: Clothes & Gear Suggestions
Given the mix of warm days, mild nights, and occasional showers, your packing list should reflect versatility.
Essentials
- Lightweight clothes: cotton shirts, T-shirts, blouses

- Light jacket or windbreaker
- A pair of trousers or jeans
- Shorts or skirts for warm midday periods
Footwear
- Comfortable walking shoes
- Sandals or breathable footwear
- Swimwear if you plan to bathe
Rain & Wind Protection
- Compact umbrella or lightweight rain jacket
- A scarf or shawl — useful for breezy or slightly cooler conditions
Accessories
- Sunglasses, sunhat, sunscreen (SPF 30+ or higher)
- Refillable water bottle
- Daypack for excursions
- Travel adapter, camera, etc.
Optional
- Rashguard for prolonged swimming
- Layers like a light fleece if venturing inland or to higher terrain
With these, you’ll be prepared for warm days, cooler nights, and any sudden shift in weather.
Daily Planning Tips by Time of Day
A simple approach helps you make the most of each day in May.
- Morning (8am–11am): Cool and comfortable; great time for sightseeing, walking, or hiking.
- Midday (11am–3pm): Warmest period; ideal for beach time, swimming, or relaxing outdoors.
- Afternoon to early evening (3pm–6pm): Still warm but slightly cooler; good for strolling through towns, visiting historical sites.
- Evening (after 6pm): Mild but sometimes breezy; a light sweater or jacket will do.
If a shower happens, it’s more likely in the afternoon or evening, so plan your outdoor endeavors earlier in the day.
Activities Suited to May Climate
Weather in May opens many opportunities:
- Beach visits and swimming (especially in warmer islands)
- Boat tours and island hopping
- Hiking and nature walks
- Visiting archaeological sites (less crowd, comfortable temps)
- Photography (flowers in bloom, green landscapes)
- Outdoor dining and seaside evenings
May is often considered an ideal time — before peak summer heat and crowds — to enjoy both cultural and leisure experiences.
Health, Comfort, and Safety Tips
- Stay hydrated — though not hot like high summer, you can still get dehydrated outdoors.
- Use sunscreen liberally — UV levels are already strong by May.
- Wear breathable, light-coloured clothing to keep cool.
- Be cautious when swimming; though sea is calmer, currents may exist.
- Check local forecasts before heading inland or to more remote areas.
When Exactly to Visit in May — Early vs Late May
The difference between early and late May can matter:
- Early May: Slightly cooler, the sea may still be marginal for swimming in some places, occasional rain more likely.
- Late May: Warmer air and sea, fewer chances of rain, more stable sunshine — you’ll feel more “summery.”
If your schedule is flexible, the latter half of May often provides the best balance of warmth and reliability.
