Weather in Malta in September

Still Summer, With Warm Seas and Easing Heat

September in Malta still feels like summer, especially during the first half of the month. Expect hot, sunny days, warm sea temperatures, and plenty of opportunities for swimming and sunbathing, as the intense August heat gradually eases.

By mid-September, evenings often become more comfortable, making sightseeing and outdoor dining more enjoyable. Towards the end of the month, the weather can become less predictable, with occasional wind, rain or thunderstorms between sunny spells.

For visitors arriving from the UK or northern Europe, September can still feel very hot, particularly in direct sunshine. It is one of our favourite months for combining beach days with exploring Malta and Gozo.

Early September (1st–10th)

Is September a Good Time to Visit Malta?

Yes, September is one of our favourite months to visit Malta, especially if you want to combine swimming, sunbathing and sightseeing.

The sea remains warm, and the intense August heat gradually eases, making it more comfortable to explore Valletta, Mdina and Gozo. We particularly favour mid-September for its balance of beach weather and pleasant evenings.

However, September is not necessarily quiet. Popular tourist areas can remain busy, and occasional wind or thunderstorms may interrupt outdoor plans, especially later in the month.

What to Wear and Pack in September

September is still a summer month in Malta, so you usually only need light, breathable clothing during the day. Hot and humid weather can continue, especially early in the month.

  • 👕 Clothing: Shorts, T-shirts, dresses and lightweight fabrics. Pack extra changes if you're sensitive to humidity.

  • 🌧️ Rain protection: A lightweight rain jacket is worth packing in case of showers or thunderstorms.

Our local tip: We still wear summer clothes throughout most of September, including in the evenings. However, we would pack one light extra layer for late September rather than relying entirely on summer clothing.
