When you know what to expect, planning gets easier. From the heat of the day to the length of daylight, every detail matters for your time in Muscat.
Here’s a rundown on temperatures, rainfall, sunshine, sea conditions, and a few travel tips—so you’ll know what spring weather really means for your visit.
Spring Weather Overview in Muscat
Muscat’s spring brings a steady rise in temperature, longer days, and more humidity. Rain gets even less common as the season goes on, while the sea warms up quickly, making the coast extra appealing.
Typical Spring Months in Muscat
Spring in Muscat runs from March through May. During this stretch, daily highs move from about 26°C (79°F) in early March to almost 38°C (100°F) by late May.
Nights warm up too, with lows rising from 19°C (66°F) to around 31°C (88°F). Rainfall? Pretty rare. The chance of a wet day drops from about 6% in March to 2% in May.
When it does rain, it’s usually light and over quickly. By late spring, skies clear up even more, and the sun takes over.
Daylight stretches out by almost two hours between March and May. Early March gives you about 11 hours 40 minutes, while late May brings nearly 13.5 hours of daylight.
This quick shift makes evenings longer and better for outdoor plans.
General Climate Characteristics
Muscat’s spring feels the effects of its subtropical desert setting. The air grows hotter and more humid as spring moves along.
In March, muggy days happen about one-quarter of the time. By late May, humidity shows up on more than half the days.
Average wind speeds stay steady at about 11–12 km/h. Winds start from the north in early March and shift to the west by late spring. This wind change can affect how comfortable you feel outside.
The sea surface temperature jumps up fast, from 24°C (75°F) in March to 31°C (88°F) in May. That’s great news for swimming and water activities.
Comparison to Oman Weather Averages
Muscat’s spring is definitely hotter and more humid than much of Oman. Inland spots, like the desert plateau, get even hotter during the day but cool off more at night, thanks to the lack of sea influence.
Muscat, right on the Gulf, keeps warmer nights. The city also sees a bit more rain than most of Oman, though totals stay very low. Muscat averages about 100 mm (3.9 inches) per year, while some desert regions barely get any.
The coast helps even out big temperature swings. Southern Oman, especially Dhofar, stays cooler in spring because of the Indian Ocean, but Muscat heats up more quickly and steadily.
All this makes Muscat one of the warmest big cities in Oman during spring.
Average Temperatures During Spring
Spring in Muscat means a steady climb in heat. You’ll notice warm afternoons turning into hot days by late May, while nights start mild and get warmer.
These changes mark the shift from comfy winter months to the intense summer that’s just around the corner.
Daytime Highs and Nighttime Lows
Daytime highs in Muscat go from about 80°F (27°C) in early March to around 101°F (38°C) by late May. You’ll really feel the afternoons get hotter as the season moves on.
Nighttime lows also rise, starting near 67°F (19°C) in March and reaching about 87°F (31°C) by the end of May. Early spring evenings feel comfortable, but nights grow pretty warm as summer nears.
The difference between day and night isn’t as big as in other desert areas. You can expect warm conditions nearly all the time, with not much cooling off at night by late spring.
This steady warmth is classic Muscat, thanks to its spot on the Gulf.
Monthly Temperature Variations
March is the most comfortable spring month, with average highs near 80–85°F (27–29°C) and lows in the upper 60s. If you like milder weather, March is your best bet.
April heats up, with highs in the upper 80s to low 90s (31–33°C) and nighttime temps in the mid-70s. The heat gets more noticeable, but evenings are still pretty manageable.
May brings the hottest spring conditions. Highs average around 100°F (38°C), and nights often stay in the mid-80s. At this point, it really starts to feel like summer, with little relief after sunset.
These shifts show how quickly Muscat warms up in spring.
Record Spring Temperatures
Averages tell most of the story, but records show how extreme Muscat’s spring can get. Highs have sometimes hit 109°F (43°C), usually in late May. That’s rare, but it happens.
On the cool side, spring lows almost never drop below 62°F (17°C), and that’s only early in the season. By late spring, nights stay warm.
These records highlight how steady Muscat’s spring weather is—hot, with only a little variation. You won’t get sudden cold snaps, which is typical for coastal Oman.
Rainfall and Precipitation Patterns
Spring in Muscat stays mostly dry, with just a bit of light rain now and then. You might notice some small changes in precipitation, but the overall vibe is arid, with not many rainy days and moderate humidity.
Monthly Rainfall Totals
Rainfall in Muscat during spring is minimal. March usually sees the highest totals of the season, averaging 10–15 mm.
April drops to around 5 mm, and May is almost dry with less than 2 mm. That’s the desert climate for you—annual rainfall is just 80–100 mm.
Most of that falls in winter, so spring barely gets any.
| Month | Average Rainfall (mm) |
|---|---|
| March | 10–15 |
| April | ~5 |
| May | <2 |
Don’t expect steady showers. Rain usually shows up as isolated, brief bursts, sometimes tied to passing weather from the Arabian Sea.
Chance of Rainy Days
Rainy days in spring are rare. March might bring 1–2 days with measurable rain.
By April, that usually drops to 1 day or none, and May is often bone dry. When rain does come, it’s short and local.
You’re not likely to get several wet days in a row. This makes planning outdoor activities in Muscat pretty easy, with little risk of weather ruining your plans.
Humidity Levels in Spring
Humidity in Muscat goes up and down with temperature and sea breezes. In March, relative humidity averages about 55–65%, which feels moderate compared to the hotter months.
By April, it dips a bit, and in May the air dries out during the day, often dropping below 50%. At night, humidity climbs, especially near the coast, sometimes reaching 70%.
This can make evenings feel warmer than the thermometer says. Expect mornings and evenings to feel more humid, while afternoons stay drier.
This mix keeps things manageable, though the heat definitely builds as spring rolls toward summer.
Sunshine and Daylight Hours
Spring in Muscat means long days and steady sunshine. Clear skies are the norm, with only a small chance of clouds or a quick shower.
The hours of direct sunlight and total daylight shift a bit from March to May.
Average Daily Sunshine
Muscat gets loads of sunshine in spring. In March, you’ll see about 9.5 to 10 hours of direct sun each day.
By May, that jumps to around 11.5 hours per day—one of the brightest times of the year.
Skies stay mostly clear, though early spring might have a few cloudy days. On average, spring skies are cloudy less than 20% of the time.
You’ll rarely lose a full day of sunshine. This steady light keeps daytime temps climbing from the low 80s °F (about 27 °C) in March to over 100 °F (38 °C) in May.
If you’re planning outdoor activities, mornings and late afternoons are the best bet for comfort.
Length of Daylight in Spring
Daylight hours in Muscat stretch out as spring goes on. In March, sunrise is around 6:20 AM and sunset about 6:20 PM, giving you roughly 12 hours of daylight.
By May, sunrise comes earlier, about 5:40 AM, and sunset pushes to nearly 6:50 PM. That’s close to 13 hours of daylight by late spring.
Long days help if you want to fit in sightseeing, sports, or day trips. Even with the strong sun, you’ve got plenty of time to balance indoor breaks with outdoor adventures.
Sea Temperatures and Coastal Conditions
Muscat’s spot on the Gulf of Oman means you get warm sea conditions all spring. Water temperatures rise steadily from late winter into early summer, and calm coastal weather makes the shore great for swimming and more.
Average Sea Temperature in Spring
Sea temps in Muscat climb fast from March through May. In March, the average water temperature sits around 24.6°C, which feels good to most swimmers.
By April, the sea warms to about 27.3°C, and in May it’s up to about 30.2°C. This matches the sharp rise in daytime air temps, from the high 20s in March to the upper 30s by May.
By late spring, the sea can feel almost bath-like. The water stays calm, and rain is rare, so you can count on stable conditions without sudden weather changes ruining your plans.
Swimming and Water Activities
Swimming in Muscat is comfortable all spring. In March, the water feels refreshing but not cold.
April and May offer very warm conditions, which many travelers love for long swims. The coast is also great for snorkeling and light diving.
Clear skies and calm seas boost underwater visibility, especially in April when the water is warm but not too hot. By May, the sea might feel less refreshing, but it’s still safe for swimming.
If you like cooler water, go earlier in spring. Don’t forget sun protection—those sunny days mean strong UV whether you’re on land or in the water.
Travel Tips for Visiting Muscat in Spring
Spring in Muscat brings higher temperatures, longer daylight, and rising humidity. You can still make the most of the season with a bit of planning, smart packing, and by checking out local activities.
What to Pack for Spring Weather
Daytime highs in Muscat during spring usually climb from the low 80s °F (around 27°C) in March. By late May, temperatures can shoot up over 100°F (38°C).
Nights stay pretty warm, so you really don’t need heavy clothing.
I’d suggest packing lightweight, breathable fabrics like cotton or linen. Loose-fitting long sleeves and trousers not only keep you cool, but they also shield you from the sun.
Don’t forget a wide-brimmed hat, sunglasses, and some high-SPF sunscreen. You’ll appreciate the extra protection.
Comfortable sandals or walking shoes make city exploring easy. If you’re planning to hike those rocky hills around Muscat, toss in sturdier shoes.
Bring a reusable water bottle, since the risk of dehydration is no joke in this heat.
If you’re heading to mosques or traditional spots, pack modest clothes that cover your shoulders and knees. Women might want to carry a light scarf for covering their head when entering religious sites.
Best Outdoor Activities
Spring feels like the perfect time to get out and see Muscat’s coastline, before the heat really takes over. You can try snorkeling or diving in the Gulf of Oman—water temperatures start around 75°F (24°C) in March and warm up to about 88°F (31°C) by May.
The Mutrah Corniche gives you a great spot for evening walks with views of the harbor. Early mornings work best for outdoor markets or exploring Old Muscat, before the sun gets too intense.
If hiking’s your thing, check out the trails in the nearby Al Hajar Mountains. Start early, bring plenty of water, and try to avoid those midday hours when the sun feels relentless.
Boat trips to the Daymaniyat Islands are also popular, especially in March and April when the weather feels more comfortable. Once May rolls in, the heat and humidity start to limit what you can do outside.
Local Events and Festivals
Spring in Muscat feels less crowded than winter, though you’ll still stumble upon cultural and community events. Religious observances sometimes change schedules, so it’s smart to double-check before making plans.
You might catch local shopping festivals in spring, with discounts and entertainment popping up in Muscat’s malls and souks. These events let you see a slice of daily life that goes beyond the usual sightseeing.
The Royal Opera House Muscat usually hosts performances this time of year, featuring everything from international music to traditional Omani shows. If you grab tickets for an evening performance, you can relax and soak up the culture indoors after a hot day outside.
Just remember, public gatherings and events might shift with the Islamic calendar, so staying flexible will help you get the most out of your visit.
