Spring and autumn are the best times to visit Syria. March to May and September to November bring comfortable temperatures, manageable crowds, and pleasant conditions for exploring ancient sites that involve a lot of walking outdoors.
Spring (March–May) is arguably the finest season. Temperatures hover between 20–25°C across most of the country, the land is green, and wildflowers appear on the hillsides around Aleppo and the coastal mountains. April is ideal.
Summer (June–September) is harsh in the interior. Damascus sits at 690 metres and stays bearable, but Palmyra and the Euphrates valley get brutal — temperatures routinely exceed 40°C in July and August. The coast around Latakia is more forgiving, with sea breezes keeping things cooler.
Autumn (October–November) is the other sweet spot. The summer heat breaks, conditions are clear and dry, and the long golden light makes ruins look extraordinary. October is particularly good.
Winter (December–February) is cold, especially inland and at altitude. Damascus can get snow. The coast stays mild. It's the least visited time, which has its own appeal — sites like Palmyra are almost completely empty — but be prepared for cold nights and the occasional road closure in the mountains.
Ramadan falls on different dates each year (following the Islamic lunar calendar). Traveling during Ramadan can be a fascinating cultural experience — the atmosphere in Damascus's old city during evening iftar is remarkable — but opening hours shift, restaurants close during daylight, and things move at a different pace. Plan accordingly.
