Muscat Weather in December

December weather

Muscat feels pleasantly warm in December, with daytime highs around 27°C and evenings near 18°C. It's the coolest, most comfortable time of year for walking around Mutrah, visiting the Sultan Qaboos Grand Mosque or taking a boat trip along the coast. December averages just two rainy days, so showers are unlikely to shape your plans.

The midday sun can still feel strong on an open stretch of the Mutrah Corniche. Save long outdoor walks for later in the day, and don't expect a beach visit to feel like a hot-weather holiday. The sea breeze can make the shore feel cooler.

What's on

December isn't a major traditional festival month in Muscat. Christmas and New Year are marked at some international hotels and restaurants, but they're not Omani public holidays. Oman's National Day falls in November, so you'll have missed its celebrations by December.

Families who prefer comfortable sightseeing to sticky summer afternoons will find December an easy month to get around. You can explore the souq and waterfront without the strain of hotter weather, though popular spots can feel busier.

Crowds and practical tips

December is part of Muscat's best season, along with January and February. Expect more visitors than in the hotter months, and higher hotel prices than during the quieter summer season. It's a trade-off: outdoor plans are much more pleasant, but you're not visiting in the low season.

For a useful local stop, visit the Grand Mosque in the morning, then head to Mutrah Souq later in the day. The mosque requires modest dress; women need to cover their hair, arms and legs. Check its visitor hours before setting out, as it's not open to non-Muslim visitors every day.
