Weather — Muscat, Oman

Muscat has a hot desert climate: mild, very pleasant winters and long, intensely hot summers. Winters (December–February) bring comfortable daytime temperatures, low humidity and occasional brief showers, while spring and autumn warm up quickly. From May through September temperatures often exceed 35–40 °C, with high sea temperatures that make mornings and evenings humid. Sunshine is abundant year-round, so plan outdoor sightseeing for cooler hours and beach time for early morning or late afternoon.

Weather in Muscat — January

January is one of the most comfortable months: average highs around 24 °C and lows near 16 °C. Expect about 9–11 hours of daylight, roughly 9–10 hours of sunshine and a warm sea at about 24 °C — ideal for sightseeing and off-peak beach visits. Rain is limited to a few short days, so pack a light jacket for cool nights and enjoy clear skies.

Weather in Muscat — February

February remains mild and pleasant with average highs near 26 °C and lows around 18 °C. Sea temperatures sit in the low 20s, and UV levels can already be high (around 8), so sunglasses and sun protection are recommended. It’s a great month for outdoor activities before spring heats up.

Weather in Muscat — April

April heats up quickly — average highs near 34 °C and mild nights around 25 °C. UV index is very high and the sea warms to roughly 27 °C, making beach days tempting but hot midday temperatures mean plan strenuous activities for mornings or evenings. Expect mostly dry, sunny conditions.

Weather in Muscat — May

May is already very hot with average highs around 38 °C and lows near 30 °C; sea temperatures reach about 30 °C.

Weather in Muscat — June

June is among the hottest months: average highs about 39–40 °C and nights around 31 °C. The sea stays warm (~31 °C) and humidity can make conditions feel heavier. Outdoor sightseeing is best before 10:00 or after 16:00; ensure plenty of water, sun protection and air-conditioned breaks.

Weather in Muscat — July

July stays extremely hot with averages near 37–38 °C by day and around 31 °C at night. Sunshine remains strong and rainfall is negligible. If you travel in July for lower fares, plan indoor or evening activities and use the sea to cool off, but be mindful of intense sun and heat stress.

Weather in Muscat — November

Best time to visit: For comfortable sightseeing pick the cooler months from November to March when daytime temperatures are pleasant and rain is minimal. If your priority is swimming and warm seas, April and October–November offer a good balance before and after peak summer heat. For lower prices and fewer tourists, travel in the hottest months (May–September) but be prepared for extreme heat.

Swimming and beaches: The sea around Muscat stays warm year-round (mid-20s to low-30s °C), so swimming and snorkeling are possible even in winter. During peak summer the water is very warm and can feel humid; if you plan water activities, aim for morning sessions for clearer water and calmer conditions.

Travel tips: Sun protection is essential year-round—UV can reach very high levels in spring and autumn. Schedule outdoor sightseeing for early morning or late afternoon in hot months, stay hydrated and favor air-conditioned transfers for longer trips. Flight deals to Muscat often follow the tourist seasons, so compare options on Flightics when planning your trip.
