As the surf in Malta is entirely dependant on wind- with no tidal factors coming into consideration at all, it will come as no surprise that conditions are most favourable during the Winter months- from October to March.
Local surfers pay close attention to the weather forecasts and are among the only individuals on the island excited to see a change from the usual hot, dry climate in favour of a storm. Of course, the cleanest swells come with onshore winds so, while there are a few breaks such as St Thomas and Playgrounds that work with a southerly wind, it’s a change to north-easterly and north-westerly winds that they’re looking out for.
In the summer air temperature averages 31°c and the sea is a balmy 25°c.
When it comes to sea temperature, you’re not going to need a 5/4 regardless of when you get in the water. It’s not unusual to see swimmers braving it in speedos in December so, even by February, a 3/2 should be more than adequate. As with the majority of Europe, the sea temperature is always 2 to 3 months behind the air temperature, so you’ll get the lowest readings (down to a minimum of 15°c) between February and April.
And if you’re fortunate enough to be in Malta during a period of swell in Summer, you can ditch the wetsuit and do away with the towel; air temperature averages 31°c and the sea is a balmy 25°c.
