Question 1

When is the driest time of year in Beirut?

Accepted Answer

The driest time of year in Beirut is summer, specifically the meteorological summer months of June to August (JJA), when the city sees almost no rain at all. In 2025, these three months together recorded just **0.6 mm (about 0.02 inches)** of total precipitation.

Beirut's dry season is remarkably consistent. June and July 2025 each registered only **0.1 mm** of rain, making June the single driest month of the year, while August added a mere **0.4 mm**. Extending the view to September, the entire June–September stretch produced just **1.0 mm** of rain — only **0.2%** of Beirut's annual total of **551.3 mm (21.7 inches)** for 2025.

This rainless period pairs with hot, bright, and humid conditions. Across summer 2025, Beirut averaged **25.8°C (78.4°F)**, soaked up roughly **940 hours of sunshine**, and held an average humidity around **75%**. August was the hottest stretch, with a peak high of **39.6°C (103.3°F)**.

For visitors, this makes the summer months the most reliable time to plan beach days, outdoor dining, and sightseeing in Beirut, with virtually no risk of a washout. The trade-off is the heat and high humidity, so light clothing, sun protection, and staying hydrated are essential. If you prefer rain-free skies but milder air, the shoulder months of late spring and early autumn offer a comfortable compromise before Beirut's wet season returns in November and December.

Question 2

How hot does Beirut get in summer?

Accepted Answer

Beirut gets hot and humid in summer, with an average temperature of about 25.8°C (78.4°F) across the 2025 summer (June to August). The heat builds steadily through the season, peaking in late summer rather than mid-summer.

Across summer 2025 (June 1 to August 31), the monthly mean temperature rose from 23.9°C (75.0°F) in June to 26.3°C (79.3°F) in July and 27.1°C (80.8°F) in August, making August the hottest month. The single warmest day reached 39.6°C (103.3°F) in August, while typical afternoon highs sat in the low-to-mid 30s°C (around 86–92°F). Even the coolest summer nights stayed mild, with the lowest minimum at 16.8°C (62.2°F) in June.

What makes Beirut's summer feel hotter is the humidity. Average relative humidity held around 75% through the season, and summer 2025 was almost completely dry, recording just 0.6mm of total rainfall over the three months.

For visitors and residents, this means warm, reliably rain-free conditions in Beirut, ideal for the coast and outdoor dining. The combination of high temperatures and humidity, however, can make midday feel oppressive, so early mornings and evenings are the most comfortable times for activity, especially during August heat spikes.

Question 3

Which season is the wettest in Beirut?

Accepted Answer

Winter is by far the wettest season in Beirut, with the meteorological winter months (December plus January and February) delivering the overwhelming majority of the city's annual rainfall in 2025.

Across the 2025 calendar year, Beirut recorded about 551 mm (21.7 in) of total precipitation. Of that, the winter months alone accounted for roughly 386 mm (15.2 in) — close to 70% of the entire year. By comparison, autumn (September to November) brought 108 mm (4.3 in), spring (March to May) just 56 mm (2.2 in), and summer (June to August) a near-bone-dry 0.6 mm (0.02 in).

The single wettest month was December 2025, with 233 mm (9.2 in) of rain, followed by February 2025 at 149 mm (5.9 in). This reflects Beirut's classic Mediterranean climate, where heavy rain is tightly concentrated in the cool season while the warm months stay almost completely dry.

For visitors, the practical takeaway is clear. If you want to avoid downpours, the late-spring-to-early-autumn window offers reliably dry weather in Beirut, with virtually no measurable rain between June and September 2025. If you don't mind wet conditions, winter brings the lush, green landscapes that the rain supports — but pack an umbrella and waterproof shoes, as a large share of the season's total can fall in just a handful of intense days.

Question 4

What is the sunniest time of year in Beirut?

Accepted Answer

The sunniest time of year in Beirut is late spring through late summer, with **May 2025 standing out as the single brightest month** at 369.2 hours of sunshine — roughly 11.9 hours of sun per day.

Across all of 2025, Beirut recorded about 3,288 hours of sunshine, averaging close to 9 hours per day over the year. The sunniest stretch ran from May to September, when monthly totals stayed high and rainfall was minimal. August 2025 was the second-brightest month with 347.9 hours (about 11.2 hours per day), followed by September at 295.3 hours and July at 297.9 hours.

May also pairs that abundant sunshine with comfortable warmth, posting a mean temperature of 21.1°C (70°F) and only 13.3mm of rain — making it one of Beirut's most pleasant months before the peak summer heat arrives. By contrast, the cloudiest month of 2025 was February, with just 178 hours of sunshine alongside heavy winter rainfall.

For visitors, this means Beirut's brightest, most reliable sunshine clusters in late spring and summer. If you want long, sunny days without the intense humidity and heat of August, May and early June offer the best balance of clear skies and milder temperatures. Those planning beach trips or extended outdoor sightseeing in Beirut should target this May-to-September window, when sunny conditions are most consistent and rainfall is rare.

Question 5

What is the annual temperature range in Beirut in 2025?

Accepted Answer

Beirut spanned an annual temperature range of about 38.4°C (69.1°F) in 2025, swinging from a peak high of 39.6°C (103.3°F) in August down to a low of 1.2°C (34.2°F) in February.

Across the full 2025 calendar year, the city's average temperature settled at 20.3°C (68.5°F), reflecting its mild Mediterranean climate. August was the warmest month, averaging 27.1°C (80.8°F), while February was the coolest at 11.3°C (52.3°F) — a 15.8°C gap between the warmest and coolest monthly means. Monthly high readings climbed above 32°C (90°F) as early as March and May, showing how quickly Beirut warms in spring.

Despite these extremes at the edges, day-to-day conditions in Beirut stay relatively moderate thanks to the coastal setting. The single cold reading of 1.2°C (34.2°F) was a brief winter dip rather than the norm, and frost is rare near the shoreline.

For visitors, this means Beirut rarely feels truly cold, but summer can bring short, intense heat spikes. The transitional months of April, October and November in 2025 offered the most comfortable conditions, with mean temperatures hovering around 18–22°C (64–72°F). Packing layers for cooler February evenings and sun protection for August's peaks is the practical takeaway for anyone planning around Beirut's 2025 temperature swings.
