Which part of Malta should you choose?

There is little weather advantage in choosing Qawra, Sliema, Valletta or Mellieha over each other in September. All have average daytime temperatures of 26°C, sea temperatures of 26°C and 4 rainy days, so none stands out as a cooler daytime option or a drier bet. Mellieha has slightly cooler nights at 22°C, compared with 23°C elsewhere, but that is a small difference rather than a reason to change your plans. Choose your base around how you want to spend your holiday, rather than expecting a different climate. For swimming, the sea temperature gives you much the same outlook across these destinations.

What to pack and how to plan your days

Pack mainly light, breathable clothes, with sun protection and a light waterproof for changeable spells. Average sunshine of 8.9 hours leaves plenty of scope for time outdoors, but 4 rainy days means a completely dry stay is not guaranteed. Keep your plans flexible rather than treating every day as a swimming day. Midday can feel hot if you are walking in direct sun, so breaks in the shade are sensible. With nights around 23°C, do not expect evenings to feel crisp; light clothing should remain useful after dark. Compared with London's September daytime average of 19°C, Malta's 26°C makes it a noticeably warmer choice.
