Malta in May: weather, crowds, sea temperature and what to do

Why May stands out as one of Malta’s best months

If you have any flexibility in your travel dates, May is one of the most compelling months to visit Malta. The island hits a sweet spot that summer cannot offer: warm enough to enjoy the sea and outdoor life, cool enough to walk sites comfortably in the afternoon, and uncrowded enough that the experience feels genuine rather than like a theme park queue.

Locals call the May–June period “shoulder season” but that undersells it. This is not a compromise month. The wildflowers are still in bloom on Gozo’s hillsides into early May. The streets of Mdina and Valletta are walkable without being shoulder-to-shoulder. Restaurant terraces have tables. The Blue Lagoon, while increasingly busy as the month progresses, is still manageable on a weekday morning.

The one honest reality: if swimming is your primary goal and you need warm water, September is technically better (sea at 25°C versus May’s 19°C). But for a visitor who wants history, walks, culture, boat trips, food, and occasional swims — May is the most well-rounded month Malta offers.

Weather in May: what to actually expect

Temperature

• Average daytime high: 21–23°C
• Average evening: 16–18°C
• Record highs (uncommon): Up to 30°C in late May during Scirocco wind events from North Africa
• What to wear: Light layers in the morning and evening. T-shirts and light trousers or shorts for midday. A light jacket for evenings (especially in early May).

Rainfall

May is one of the transitional months from Malta’s brief wet season (November–March) to its dry summer. Early May can still see occasional afternoon showers — typically brief and dramatic rather than all-day rain. From mid-May onwards, rain becomes genuinely rare (fewer than 3 rainy days on average for the full month).

The honest advice: bring a compact packable rain jacket. You may never use it. But a surprise shower in front of the Hagar Qim temples is much less bothersome if you are prepared.

Sea temperature

At 19°C in May, the sea is genuinely swimmable for most Europeans and North Americans — this is approximately the same temperature as a comfortable outdoor pool. Some visitors from northern climates will find it refreshingly cool rather than cold. The sea at Malta’s south coast (St Peter’s Pool, Blue Grotto area) is typically 1°C warmer than the north (Mellieha Bay) due to exposure.

Comparison:

Month	Sea temp	Air temp
April	17°C	18°C
May	19°C	21°C
June	22°C	25°C
September	25°C	26°C

What to do in Malta in May: best activities by type

History and culture: at their best in May

May is the ideal month for visiting Malta’s heritage sites without the summer crowd penalty. Valletta — which in August sees streets so congested that walking becomes uncomfortable — is calm and genuinely enjoyable in May.

St John’s Co-Cathedral (Valletta): Queues of 30–60 minutes in summer are non-existent in May. You walk in, take your time with the Caravaggio paintings, and leave when ready. €15 entry, well worth it.

Hagar Qim and Mnajdra temples (south Malta): The clifftop temples are stunning year-round, but in May the surrounding landscape is still green from winter rain. The Hagar Qim guide covers logistics. Go before 10 am to have the temples largely to yourself.

Mdina: The medieval walled city is an entirely different experience in May versus August. In August, it is shoulder-to-shoulder groups. In May, the narrow lanes are navigable at human pace. Sunset from the Mdina bastions in May — with a clear sky — is one of Malta’s finest experiences.

Gozo and Citadella: The Gozo day trip is excellent in May. Gozo’s interior is still lush. The Citadella in Victoria has minimal queues. The coastal walks (Xlendi valley, Ramla Bay) have comfortable hiking temperatures.

Beaches and swimming: possible but not the priority

The sea at 19°C is swimmable. Most visitors who go to Malta in May will swim at least once. But swimming is not the main reason to come in May — you come for everything else, and the swimming is a bonus.

Best May swimming spots:

• St Peter’s Pool (south coast): Rocky ledge with clear water, popular but not overwhelmed in May
• Mellieha Bay: Malta’s largest sandy beach, still relatively uncrowded in May, shallow-entry ideal for families
• Ramla Bay (Gozo): Red sand (unusual for Malta), beautiful setting, limited facilities in early season

Blue Lagoon (Comino) in May: This is where honest advice matters. The Blue Lagoon in May is a genuinely different experience from July–August. On a Tuesday morning in May, you might arrive to 50 people on the rock. By late May on a Saturday, that number climbs to 300–400. Still manageable, still beautiful — but the window for a peaceful experience is closing. Book early morning departures and go in the first half of May for the best version of the Blue Lagoon.

Boat trips: comfortable conditions

May’s combination of mild temperatures, minimal wave action, and moderate boat traffic makes it excellent for Malta’s cruise and sailing experiences. The sea is calm enough for snorkelling, and operators are running full schedules without the August overbooking situation.

The Comino, Crystal Lagoon and Blue Lagoon cruise from Sliema↗ is an excellent May option — the morning sea conditions are typically flat, and the two lagoons in combination give you a full morning on the water.

The Gozo full-day tour visiting Ggantija temples, salt pans and Dwejra↗ is ideal for a May itinerary — full day in Gozo without driving yourself, covering the island’s cultural and coastal highlights.

Events in May (and late April)

Malta International Fireworks Festival (late April)

Technically, the Fireworks Festival takes place in late April rather than May — usually the last Saturday and Sunday of April. It is worth mentioning here because many visitors arriving in early May will have just missed it, and those with flexible booking should consider arriving a few days early.

The festival involves competitive fireworks displays over the Grand Harbour in Valletta, with international teams competing alongside Maltese pyrotechnic clubs. It is free to watch from the Valletta bastions (Upper Barrakka Gardens or the Saluting Battery area), from Sliema waterfront, or from the Three Cities waterfront. The Fireworks Festival cruise from Valletta Harbour offers the best viewing angle — the Fireworks Festival Grand Harbour cruise↗ sells out weeks in advance, so book early if this is your reason for the trip.

The honest reality: The harbour cruise is excellent but requires booking 4–6 weeks ahead. Free viewing from the bastions is also excellent — just arrive 90 minutes before the display starts (typically 9 pm) to secure a bastion ledge spot.

Village festas: beginning of the season

Malta’s famous summer festas (village saints’ days with fireworks, brass bands and processions) technically begin in late May or early June, though the main concentration is July–August. A few villages hold their festa in May or early June.

The festas guide has the annual calendar. In 2026, check for Qormi, Siggiewi and Mqabba in the late May – early June window.

Maltese Folk Festival (May)

A smaller event compared to the Fireworks Festival, the Maltese Folk Festival typically takes place in May in Valletta’s open spaces. Traditional music, folk dance, local food stalls, and cultural demonstrations. It is free and local in character — a genuinely authentic contrast to the tourist-directed events.

May crowds: the honest assessment by zone

Valletta: low-moderate

Walking comfortably. No queues at the major sites (book online for St John’s Co-Cathedral to guarantee entry). Restaurant terraces available. The ferry to Sliema runs on its regular schedule and rarely has waits. This is Valletta at close to its best visitor experience.

Sliema / St Julian’s: moderate

The promenade is busy on weekends but not crushed. Restaurants generally have availability without booking in advance (unlike August when 7 pm without a reservation means standing in the street). Hotel prices are 15–30% below peak summer rates.

Mdina: low-moderate weekdays, moderate weekends

Weekday mornings in Mdina in May approach the feeling of having the city to yourself. On Saturday afternoons in late May, tour groups begin to appear. Sunday is the busiest day. Ideal visit: weekday, before noon.

Comino / Blue Lagoon: manageable if timed right

The Blue Lagoon in early May on a weekday is among Malta’s genuinely special experiences — turquoise water, minimal crowds, the white rock largely to yourself. By the last week of May on a Saturday it is busy enough to feel congested. Go on a Tuesday or Wednesday, depart before 9:30 am, leave by 1 pm.

Gozo: quiet

Gozo in May is calm, green and genuinely unhurried. The island is at perhaps 30–40% of its July–August visitor volume. This is the best time to experience Gozo as Gozitans do — explore the market in Victoria on a Tuesday morning, eat rabbit stew at a village restaurant, walk the Xlendi valley coastal path without meeting another tourist.

Practical May travel tips

Booking in May versus summer

Flights: Malta is served by numerous European carriers (Ryanair, easyJet, Air Malta, Lufthansa, Vueling). May prices are typically 20–40% below July–August peaks from most European cities. Book 4–6 weeks ahead for reasonable fares.

Accommodation: Good availability in May. Hostels have dorm beds available with 1–2 weeks’ notice. Mid-range hotels have rooms without the premium pricing. If you want a specific location (Valletta, St Julian’s waterfront), booking 2–3 weeks ahead is comfortable.

Tours: GYG tours run full schedules in May. Most have availability within the week of travel. The main exception is the Fireworks Festival cruise (book weeks ahead) and private charters.

What to pack for May

• Swimsuit: One or two — you will use them
• Light layers: A long-sleeved top and a packable rain jacket
• Sun protection: The Mediterranean spring sun is deceptive — UV levels are already significant in May. SPF 30+ daily
• Comfortable walking shoes: Cobblestones in Valletta and Mdina require flat soles or light hiking shoes
• Light sandals: For beach and boat days

Frequently asked questions

Is the sea warm enough to swim in Malta in May?

The sea averages 19°C in May. Most Europeans will find this comfortable for swimming, especially in the sheltered southern coves (St Peter’s Pool, Blue Grotto area) which can feel slightly warmer. If you are acclimatised to cold water, 19°C feels warm. If you come from the tropics, you may find it cool. A spring wetsuit is not needed — a swimsuit is fine.

Are the boat trips to Comino running in May?

Yes, fully. May is within the main operating season for Comino boats. The Mellieha Marfa ferry to Comino (for foot passengers) runs regularly, and all major tour operators run Comino cruises from Sliema, Bugibba and St Julian’s. Check specific operator schedules for early May (some smaller operators start in the second or third week of May).

Is the Fireworks Festival in April or May?

The Malta International Fireworks Festival takes place in late April — the last weekend of April in most years. If you want to attend, adjust your arrival to late April. The last week of April and first week of May together make an excellent trip if you want both the festival and the shoulder-season experience.

How does May compare to October in Malta?

Both are excellent shoulder season months but with different character. May: greener landscape, slightly cooler water (19°C vs. 23°C in October), Fireworks Festival at the end of April, and the festas season just beginning. October: warmer sea, Notte Bianca event in Valletta, slightly cooler air (22°C), but landscape is dry after the summer. Read the Malta in October guide for a direct comparison.

Can I see wildflowers in Malta in May?

Early May still has some wildflowers, particularly in Gozo and rural central Malta. The peak wildflower period is March–April. By the second half of May, the landscape is transitioning toward its summer dry-gold appearance. If wildflowers are a priority, plan for April rather than May.
