Although Langkawi falls into the tropical weather zone, but unlike many other parts of Malaysia, it enjoys far more sunshine, dry spells and a stable weather. This is mainly because it is well protected by the Malaysia’s mainland on its east and the Indonesian island Sumatra on its west.

So if you plan to visit Langkawi anytime of the year, you can expect enough sunshine during the day time even during the rainy season. While there may be rains, thunders and even continuous lightning splitting the sky in the evenings and striking the ocean, next morning when you wake up, you will again likely find a bright & clear day.

The first time when we came to the island in September, it was initially a bright day with a clear sky. But later in the afternoon as we sat in an open air restaurant, we saw dark cloud gathering and soon engulfed the entire sky. Then started a strong breeze, then drizzle and then torrential rain with thunders. With a heavy heart we thought that was the end of our vacation.

But next morning it was all gone. The sky was clear as ever and the sun shining brightly. We learned that even during rainy season, it would usually shower only for a couple of hours and that too in the late afternoon or evening or at night. But Langkawi’s most prevailing weather is sunny, bright day, enough sunshine, warm and with some humidity. Anybody who loves a tropical warm weather, would find this island a piece of paradise.
