Summer has officially arrived, and with it comes the season’s first expected heat wave, according to Maltese Islands Weather.

The term ‘heat wave’ is often used casually, but it has a specific meteorological definition. A heat wave occurs when daytime temperatures exceed the average maximum for the time of year by 5°C or more, for at least three consecutive days.

To better understand this, the mean maximum temperatures for Malta are as follows:

• June: 28.5°C (Heat wave threshold: 33.5°C+)
• July: 31.6°C (Heat wave threshold: 36.6°C+)
• August: 31.7°C (Heat wave threshold: 36.7°C+)
• September: 28.5°C (Heat wave threshold: 33.5°C+)

Based on these standards, Maltese Islands Weather has identified Friday 27th, Saturday 28th, and Sunday 29th June as the first official heat wave of 2025.

Forecasts are predicting highs of 36°C to 37°C, well above the June threshold.

Locals and tourists are advised to take necessary precautions - stay hydrated, avoid strenuous activity during peak sun hours, and check in on vulnerable individuals.

As the island basks in its summer sunshine, it’s important to enjoy the season responsibly and remain weather aware.

So, stay cool and stay safe!
