Byblos, located in Lebanon, boasts a classic Mediterranean climate. This means visitors can expect hot, sunny, and mostly dry summer months, while winters here are mild and wetter.

Two main seasons are clearly defined. Summer, especially from June to September, is characterized by high temperatures, with average values ranging from 22°C to 25°C and maximums reaching 28°C. Rainfall is minimal during this period, often nonexistent, making it ideal for sun and sea lovers. Winter, from December to March, brings cooler weather with average temperatures around 10-13°C. The bulk of the precipitation falls during the winter months, although it is never excessive.

The transition seasons—spring (April–May) and autumn (October–November)—offer a pleasant mix of warm weather and a moderate number of sunny days, with gradual changes in temperature and rainfall. A hallmark of Byblos's climate is its very dry summer period, which is particularly important to consider when planning outdoor activities.

The city of Byblos experiences distinct seasonality in the distribution of precipitation throughout the year. A wet winter period and a very dry summer are clearly observed, which is characteristic of a Mediterranean climate.

The majority of precipitation falls during the winter months. The rainy season typically lasts from late autumn to early spring. January is the wettest month, with an average rainfall of 6 mm and approximately 16 rainy days. December, February, and March are also characterized by frequent but, judging by the total volume, mostly light or moderate rain. For example, in December and March, there are 13–14 days with precipitation, although the total amount is small (3–4 mm). Snow is unlikely, given the average monthly temperatures.

In contrast, the summer months are extremely dry. July stands out as the driest period, when no precipitation is observed at all. June, August, and September are also virtually rainless, with zero rainfall and only 1–2 days when a negligible amount might fall. Transition months such as May and October are also characterized by a low probability of precipitation (1 mm and 4–6 rainy days, respectively), marking the beginning and end of the dry season.

When planning a trip to Byblos, it's important to consider its Mediterranean climate with hot, dry summers and mild, wetter winters. During the summer months, from June to September, when the average temperature ranges from 22°C to 25°C and rainfall is virtually nonexistent, your wardrobe should consist of light, breathable clothing. Don't forget swimwear, high SPF sunscreen, a hat, and sunglasses. Comfortable walking shoes are a must, as you will likely spend a lot of time exploring the city's ancient ruins and streets.

From late autumn to early spring (November to March), the weather in Byblos becomes cooler, with average temperatures dropping to 10-16°C, and the likelihood of rain increases, especially from December to February. During this period, it is recommended to bring warmer clothing: sweaters, fleece tops, a light jacket or windbreaker, as well as waterproof outerwear or an umbrella. The principle of layering will be very useful here, allowing you to adapt to temperature changes throughout the day. Closed-toe shoes will also be more appropriate.

In the transition seasons, spring (April–May) and autumn (October), the weather is usually very comfortable, with temperatures ranging from 15°C to 23°C. Layering is also key during this time: light sweaters, cardigans, or jackets that can be removed during the warm daytime and put on during a cool evening. Regardless of the time of year, don't forget an adapter for your electronics if needed and a small first-aid kit with basic medications.
