Is this still relaxation? Why a Halkidiki holiday during the autumn break could be a good idea
The Halkidiki peninsula in northern Greece is best known for its sandy beaches, clear waters and Mediterranean landscape. While most tourists prefer the summer, the autumn holidays (September to October, depending on school holidays in the UK) offer a quiet, often very pleasant alternative: fewer people, relaxed towns, a mild climate and often good conditions for walks, culture and even extended days at the beach.
Typical weather during the UK autumn holidays
- Temperatures (day): During the autumn holidays (usually from late September to mid/late October), average daytime highs in Chalikidi are typically between 20°C and 26°C — often warmer in early autumn and cooler towards the end of October.
- Temperatures (night): At night, temperatures cool down to around 12°C to 18°C. On clear nights, it can get a little cooler in some places.
- Water temperature: The sea has warmed up over the summer. In September, water temperatures are often still between 22°C and 25°C, in October they usually drop to 19°C–22°C — often still pleasant for cooler swimmers, but September is ideal for those who prefer warmer water.
- Rainfall & sunshine: Autumn brings occasional rain showers, especially towards the end of October. Nevertheless, there are many dry, sunny days — the transition to the wetter season is usually gradual.
- Wind: There may be occasional stronger winds (sea breeze), especially on exposed coastal areas. Storms are rare but possible.
Can you still go swimming during the autumn holidays?
Short answer: Yes — especially in September and often in the first half of October.
More details:
- September is usually still the best time for swimming during an autumn holiday in Halkidiki: warm air, warm water, ideal conditions for beach days and water sports.
- October: Depending on how late the autumn holidays are, swimming is still possible, but the water feels noticeably cooler. For many, this is still acceptable, especially on sunny days. The wind can cause the water to cool down quickly.
- Practical tips: If you are sensitive to cooler water temperatures, plan your swimming times for the warmest hours of the day or choose bays that are sheltered from the wind. A light wetsuit is an option for long snorkelling or surfing sessions.
Activities that are particularly enjoyable in autumn
- Hiking & coastal walks: Temperatures are ideal for moderate to longer tours without the summer heat.
- Culture & cuisine: Local taverns, wineries and museums are now more relaxed to visit. Seasonal specialities (mushrooms, grapes, olive harvest) are available at the markets.
- Boat trips & peninsula tours: Many operators are still running — often at lower prices and with fewer people.
- Photography: Golden autumn light, quiet beaches and dramatic coastlines offer great photo opportunities.
FAQ — Common Questions from Interested Travellers
How reliable is the weather in the second half of October?
The weather in October is more changeable than in September. With each passing day, the likelihood of cooler temperatures and occasional rain fronts increases. However, there are still often stable, sunny periods. Those who can remain flexible have a very good chance of enjoying pleasant days.
Do I need heating or warm clothing for an autumn half-term holiday?
During the day, light summer clothing is often sufficient, but in the evenings and at night, a light jacket, jumper, and possibly a warmer coat for windy evenings are recommended. It can feel noticeably cooler in shaded areas and during rainy spells.
Are restaurants and hotels still open?
Many hotels, guesthouses, and restaurants remain open during the autumn half-term — especially in popular tourist areas and larger towns. Smaller seasonal businesses sometimes close in late October. It’s always worth booking in advance or checking ahead.
How does the sea water in October compare to Germany in summer?
In the early autumn months, the sea is significantly warmer than the North Sea and Baltic Sea in the summer. Towards the middle/end of October, however, the water temperatures tend to approach more moderate values — for many people, a holiday in Halkidiki during the autumn holidays is therefore still more pleasant than on the German coast in July.
Is it worth renting a car in autumn?
Yes. The roads are quieter, parking spaces are easier to find, and a car gives you more flexibility — especially if you want to explore different bays, villages and destinations without any time pressure.
What about insects/mosquitoes in autumn?
The mosquito season decreases significantly towards the end of autumn. Mosquitoes may occur sporadically in wetlands or after rainfall — otherwise, the situation is much more relaxed than in midsummer.
Are beaches clean and safe for swimming in autumn?
The beaches are generally clean; local authorities and communities continue to maintain them outside the peak season. Pay attention to local warnings and flags (e.g. in case of strong winds or currents).
