Malta Heatwave 2026: Temperatures, Humidity & Safety

Last updated: Jul 29, 2026

Malta is one of the hottest and driest corners of the Mediterranean in high summer, and the thermometer only tells part of the story. Between the humidity, the dense limestone towns that trap warmth, and the occasional blast of desert air, a 34C day in Valletta can feel a lot more punishing than the same reading somewhere breezier.

This guide explains how hot Malta actually gets, what the records and warnings mean, and how to plan a comfortable trip. If you are already mapping out a summer visit, you can compare flights to Malta International Airport and browse hotels across Malta as you read.

Quick facts: Malta just came through its hottest stretch of 2026 so far, with a red heat warning and a new July temperature record.
Malta’s highest reliably recorded temperature is 43.8C (9 August 1999, Luqa); the new July record is 43.3C, set on 18 July 2026.
A typical July or August day runs 31C to 34C, with nights around 22C to 24C.
July’s average humidity is around 69%, which is why the “feels like” temperature usually runs several degrees hotter than the thermometer.

As of late July 2026, Malta has just come through one of its most intense heatwaves on record, including a red weather warning, a new July temperature record, and localised power cuts. A brief spell of thunderstorms has since brought some relief, though forecasters expect the heat to build again from the weekend, with highs feeling as hot as 38C.

How hot Malta gets, and why humidity is the real story

Malta’s daytime highs sit in the low 30s Celsius in a typical July or August, with humidity doing most of the work in how punishing the heat feels. On a typical day, highs run roughly 31C to 34C, with overnight lows staying warm at around 22C to 24C.

Those numbers alone sound manageable for anyone used to Gulf summers. The difference is the air, and a handful of local factors make it feel worse than the number on the forecast.

High humidity. Malta sits in the middle of the sea, so summer humidity stays high; the July average relative humidity is around 69%, and mornings are often more humid still.
Limited sweat cooling. Warm, moist air makes the body less able to cool itself through sweat, so the “feels like” temperature runs several degrees above the actual reading.
Dense, stone-built towns. Valletta, Sliema, and the harbour districts are packed with limestone buildings and narrow streets that soak up heat by day and release it slowly at night.
Scarce shade. Natural shade is limited, and the stone keeps radiating warmth well after sunset, which is why nights can feel stifling.

During the July 2026 heatwave, real-feel readings topped 42C on days when the official high was around 40C. That gap between the thermometer and how the heat actually feels is the single most important thing to plan around.

Malta’s temperature record, the xlokk wind, and MaltaMet warnings

The national record

Malta’s highest reliably recorded air temperature is 43.8C, set on 9 August 1999 at Luqa, the site of the main airport weather station. That figure still stands as the national all-time record.

July 2023 had been the hottest single month in the Malta Meteorological Office’s records, with a mean temperature of 29.6C, and its peak of 42.7C on 24 July matched a July record that had stood since 1998. That July record has since been broken: on 18 July 2026, Malta reached 43.3C, its hottest July day on record, just 0.5C below the all-time August 1999 mark.

The spell that produced that reading was unusually persistent. Local reporting described it as the first time on record that temperatures topped 42C on three consecutive days, driven by a stalled high-pressure pattern known as an “Omega Block” that kept conditions hot, dry, and settled for an extended stretch.

The xlokk (sirocco) wind

Some of Malta’s most oppressive heat arrives on the xlokk, the Maltese name for the sirocco: a hot, humid south-easterly wind that blows up from North Africa. When the xlokk sets in, it can spike temperatures quickly and carry fine desert dust that turns the sky a hazy, milky white and coats cars and balconies in a thin film.

It is the same weather setup that drives many of Malta’s sharpest heat events, including the mid-July 2026 spell.

Heat warnings

The Malta Meteorological Office declares a heatwave once conditions run hot for several days in a row, then issues colour-coded warnings and mobile alerts with practical advice. A local heatwave is broadly defined as three or more consecutive days with maximum temperatures at least 5C above the monthly average, and a red warning marks the most extreme spells.

In mid-July 2026, the Met Office issued a red weather warning, its highest alert level, as temperatures were forecast to reach 40C to 41C over several days. The Health Ministry issued a parallel excessive heat warning, escalated its Heat Health Action Plan, opened cooling centres for vulnerable residents, and sent mobile text alerts telling people to keep cool, stay out of the sun, and drink water.

Check the official Malta Meteorological Office forecast before and during your trip.

Valletta, Sliema and St Julian’s in the heat, plus cooler options

The busiest tourist areas in Malta are also some of the warmest to walk around at midday, though a few pockets offer relief. In Valletta, the honey-coloured fortifications and stepped streets are stunning, and they radiate heat; the shadeless upper squares can be tough between roughly noon and 4pm.

Sliema and St Julian’s, the main hotel and nightlife strips along the coast, get a little sea breeze but are heavily built up, so the pavements stay hot into the evening.

Choosing where to stay

Air conditioning is now standard in most tourist-grade hotels in Malta, though some older guesthouses and budget apartments still rely on fans or weaker units, so it is worth confirming before you book. During the hottest spells of July 2026, localised power cuts also hit several localities as demand strained the electricity grid, so a room with reliable AC and a backup plan for a short outage is worth the extra check.

You can filter and compare hotels in Valletta and hotels in Sliema to find properties with proper AC.

Where to cool down

The sea is your best friend. Malta’s water typically warms into the high 20s Celsius by late summer, and in July 2026 it briefly ran even warmer, with a strong marine heatwave pushing sea temperatures near 29C around Gozo. A swim is still the quickest way to reset on a hot day, and rocky lidos around Sliema and sandy bays in the north are busy but effective.
Air-conditioned museums and indoor sights make good midday shelter. Valletta’s museums, St John’s Co-Cathedral, and the larger galleries let you sightsee without frying in the sun.
Gozo, Malta’s greener sister island, tends to feel a touch calmer and more open than the dense towns of the main island, and its coast and countryside offer more room to breathe on a hot afternoon.

How to stay safe and cool

Heat in Malta is manageable if you follow the same core advice Maltese health authorities give during hot spells. The list below covers the essentials.

Avoid the midday sun. Do your walking, sightseeing, and hiking before 11am or after 4pm, and rest indoors or in shade during the peak.
Drink water constantly, before you feel thirsty, and go easy on alcohol and caffeine, which speed up dehydration.
Dress for it: light, loose, pale clothing, a wide-brimmed hat, sunglasses, and high-SPF sunscreen reapplied through the day.
Watch the vulnerable. Older travellers, young children, pregnant women, and anyone with a heart or respiratory condition feel the heat harder and need extra care; local health guidance also urges checking in on elderly relatives, neighbours, and anyone living alone.
Know the warning signs of heat exhaustion and heatstroke: dizziness, headache, nausea, a rapid pulse, and confusion. Move to shade, cool down, and rehydrate at once, and seek medical help if symptoms are severe.
Plan for possible power cuts. Localised outages hit several Maltese towns during the hottest days of July 2026 as grid demand hit a record high, so keep a power bank, torch, and bottled water on hand during a red-warning spell.

One quiet reassurance: Malta produces more than half of its drinking water by desalination, so the tap supply does not depend on summer rain. Bottled water is widely sold, and staying hydrated is easy.

When to go, and booking tips

For sun without the fiercest heat, the shoulder seasons beat peak summer. Aim for May to mid-June or mid-September through October, when the sea is warm, the days are long and bright, and daytime temperatures are far more comfortable for exploring on foot.

July and August deliver the hottest, driest weather, the biggest crowds, and the occasional red-warning spell like the one in mid-July 2026, which suits committed beach and sea lovers who plan their days around the heat.

Book a hotel with reliable air conditioning

In peak summer this is the single most important comfort factor. Confirm the room has its own working AC, not just a lobby unit or a ceiling fan.

Compare Malta hotels and read recent reviews for mentions of cooling before you commit.

Keep your flights flexible

Summer schedules are busy, and weather or strikes elsewhere in Europe can ripple through. Booking a flexible fare gives you room to shift dates around a heatwave or a travel disruption.

You can compare flights to Malta across airlines, and the national carrier, KM Malta Airlines, connects the islands with cities across Europe from its Malta International Airport hub.

Frequently Asked Questions

How hot does Malta get in summer?

Daytime highs in July and August typically sit around 31C to 34C, with warm nights near 22C to 24C. High humidity pushes the “feels like” temperature several degrees higher, and heatwaves can send readings into the low 40s, as happened in mid-July 2026.

What is the hottest temperature ever recorded in Malta?

43.8C, recorded on 9 August 1999 at Luqa. The hottest July day on record is 43.3C, set on 18 July 2026, just 0.5C short of the all-time mark.

Is it too hot to visit Malta in July and August?

It is intense but very doable. If you plan around the midday heat, stay hydrated, and book accommodation with good air conditioning, a summer trip works well, though it is worth checking for active heat warnings before you travel. For milder weather, May to mid-June and mid-September to October are the sweet spots.

What is the xlokk?

The xlokk is the Maltese name for the sirocco, a hot, humid south-easterly wind from North Africa that can spike temperatures sharply and fill the sky with fine desert dust.
