The best time to visit Valletta for pleasant weather is late spring and early summer, especially May and June, when temperatures stay warm without being overly hot and rainfall is minimal.
May and June greet you with long, sunny days—perfect for wandering the city’s historic streets or catching those waterfront views.

Understanding Valletta’s Climate
Valletta sits in a Mediterranean climate zone, shaped by warm summers, mild winters, and loads of sunshine. You’ll notice temperature, rainfall, and humidity shift with the seasons. That definitely affects how comfortable you’ll feel exploring the city.
Mediterranean Weather Patterns
Valletta gets the classic Mediterranean deal—hot, dry summers and mild, wetter winters. Summers usually mean long stretches of blue skies and barely any rain.
Winters stay pretty gentle compared to places farther north, though this is when most rain falls.
The city’s spot on Malta’s eastern shore brings in sea breezes that cool things down, especially in summer. That breeze makes outdoor adventures a lot easier.
Winters never get harsh, with daytime temperatures well above freezing.
This mix of warmth, sunshine, and manageable rain keeps Valletta attractive in different seasons. The climate stays steady enough for you to plan ahead, whether you’re after dry or cooler days.
Temperature and Rainfall Overview
In Valletta, temperatures swing from about 14°C in January to 28°C in August. Nights cool off but still feel comfy, with lows around 13°C in winter and 26°C in peak summer.
Rain doesn’t spread out evenly over the year. November and December bring the most rain, sometimes topping 70–100 mm. July is almost bone dry, often with less than 1 mm.
Here’s a quick look:

Best Months to Visit Valletta for Pleasant Weather
Spring and autumn really deliver Valletta’s best weather. You get warm but not overwhelming temperatures and reliable sunshine, making it easy to wander the city or hang out by the coast.
Ideal Temperatures for Outdoor Activities
For sightseeing and walking tours, April to June and September to October are the most comfortable months. Daytime highs usually land between 18°C and 25°C (64°F to 77°F). Nights stay mild, so outdoor dining or evening strolls feel just right.
Summer, especially July and August, often climbs to 28°C to 30°C (82°F to 86°F). That’s still doable, but the heat and strong sun can make long walks pretty tiring. Winters cool down to 13°C to 16°C (55°F to 61°F), but it’s rarely cold enough to keep you indoors.
If you’re planning to visit places like Upper Barrakka Gardens or walk Valletta’s fortifications, spring and early autumn offer the best mix of comfort and daylight. Summer brings the least rain, but spring and fall still have lots of sunshine and fewer crowds.
Sea Conditions and Swimming Season
The Mediterranean around Valletta warms up slowly in spring. By late May, the sea hits about 20°C (68°F), which many people find fine for swimming.
The warmest water comes between June and September, when sea temperatures reach 24°C–26°C (75°F–79°F).
If swimming’s a top priority, aim for summer or early autumn. September is great since the sea is still warm from summer, but the air feels a bit cooler—perfect for sightseeing too.
Winter drops sea temperatures to 15°C–16°C (59°F–61°F). That’s too cold for most, but the coast stays nice for walks, harbor cruises, or ferry rides to the Three Cities. On calmer days, boat trips are still a good bet in spring and autumn.
Tourist Seasons and Crowds in Valletta
Travel patterns in Valletta change with the seasons. Warm, dry summers pull in the biggest crowds, while cooler months bring fewer visitors and a slower vibe.
Your experience really depends on the time of year you pick.
High and Peak Tourist Periods
June through August marks Valletta’s busiest stretch. Summer means long, sunny days, average highs hovering around 30–31°C, and barely any rain.
Cruise ships dock, families on vacation arrive, and travelers from all over Europe pour in.
During these months, you’ll notice crowded streets, steeper hotel prices, and longer lines at spots like St. John’s Co-Cathedral or the Grand Master’s Palace.
Outdoor cafes and the waterfront buzz with activity, but it’s tough to find quiet moments for exploring.
Events like the Isle of MTV festival in July crank up visitor numbers even more. If you’re into nightlife and a lively scene, summer’s your season.
Still, sightseeing in the heat gets exhausting, especially since those narrow stone streets trap warmth.
Late spring (May to early June) and early autumn (September) also draw plenty of visitors.
These months strike a nice balance—warm weather, smaller crowds, and more comfortable conditions for wandering or soaking up harbor views.
Off-Peak and Low Season Advantages
From November through March, Valletta slows down. Temperatures dip to highs of about 15–17°C, and rain shows up more often.
The weather can be a bit unpredictable, but the city feels much quieter.
You’ll find lower accommodation costs and more breathing room at the big attractions. Museums, churches, and historic palaces are easier to appreciate without huge crowds.
If you like slower travel and less noise, this is the time to visit.
Winter isn’t dull, though. Events like the Carnival of Malta in February and the Valletta International Baroque Festival in January showcase local traditions, minus the summer rush.
Spring and autumn shoulder seasons (April–June, September–October) offer mild weather with manageable visitor numbers.
You can explore at your own pace, skip the peak-season chaos, and still join in on outdoor activities like harbor cruises or walking tours.
Weather Considerations for Planning Your Trip
Valletta’s climate brings warm, dry summers and mild, wetter winters.
It’s smart to plan around seasonal changes in temperature, rainfall, and daylight to get the most from your trip.
Travel Tips by Season
Spring (March–May): Days stay mild, usually 16–20°C (60–68°F). Rain tapers off by April, and you get more sunshine, which makes it a great time for walking tours.
Crowds are smaller than in summer, so you can stroll the historic streets without dodging too many people.
Summer (June–August): You’ll get hot, sunny days, highs near 27–29°C (80–84°F). Rain barely shows up, and July’s often wall-to-wall sunshine.
If you love swimming or lazy beach days, this is your window. Just know it’s peak tourist season, and those afternoon temps can feel pretty intense.
Autumn (September–November): Early autumn stays warm, around 23–26°C (73–79°F). September still works for swimming, but by October and November, rain picks up, especially in November, which gets the most rain all year.
This season’s great if you want fewer crowds and don’t mind the odd shower.
Winter (December–February): Winters in Valletta are mild, with highs about 15–17°C (59–63°F). Rain falls more often, but it usually doesn’t last all day.
You’ll find the city at its quietest, with lower prices and more room at the big sights.
Packing Recommendations Based on Weather
For spring, you’ll want to toss in some light layers—think t-shirts and maybe a thin sweater or hoodie. March and April can get rainy, so I’d suggest packing a small umbrella or a light rain jacket.
In summer, stick with breathable stuff like cotton shirts, shorts, and easy dresses. Sun protection matters here, so don’t forget your sunglasses, sunscreen, and a hat. The evenings usually stay warm, so you can skip heavy layers.
During autumn, go for versatile clothes. September still feels like summer, but by October and November, you’ll probably need a light jacket and waterproof shoes. A compact raincoat comes in handy for those surprise showers.
For winter, grab some long pants, a few light sweaters, and a medium-weight jacket. It doesn’t really get very cold, but the evenings near the coast can feel a bit chilly. Since rain shows up more often, waterproof footwear makes sense.
