Malta's climate is reliably good for most of the year, but the gap between shoulder season and peak summer is bigger than you might expect.
- April to June
- Temperatures around 20–25°C, the sea warming up, crowds still manageable. May is widely considered the sweet spot: green countryside, open water, no peak-season pressure.
- July to August
- Peak season: highs of 31–32°C, long days and excellent beach conditions. The Blue Lagoon gets extremely busy. Expect higher prices and book everything — especially the Hypogeum — well in advance.
- September to October
- The sea stays warm from a full summer of sun, temperatures drop to a comfortable 25–29°C and the crowds thin out fast. Late September and October are ideal for diving, walking and sightseeing.
- November to March
- Low season: cooler (around 16–17°C), wetter and cheap. Swimming is off the table, but Valletta and Mdina are at their least crowded. Good for history-focused trips on a tighter budget.
