« Rain brings renewal and freshness, calmness 🙏 Warm tropical rain is totally not the same as that summer rain from colder climates 😏 Even in terms of sensations here, in the tropics, the rain feels lighter and denser... it carries life-giving moisture, and here it also evaporates and hangs in the air like a blanket of humidity...

Our summer rain in the tropics is like... well, completely different, "momental"... these drops are heavy and saturated, more than the stale, sluggish rains we know. What can I say about our autumn torrential rains... 😏 »

I absolutely love this climate and the vibrant, juicy colors that surround me. 🌴 In February, the weather in Samui is just perfect. 🌞 During the day, there’s no scorching heat, the evenings are fresh, and there’s no stuffiness. We haven’t had any rain yet. Just the sea, fruits, sunshine, and massages! 💖 That’s why I adore Thailand more than anything else. »

« In Koh Samui, it's the season of winds and thunderstorms⛅⚡—it's cool while the sun is blazing, and then a moment later, it's pouring like there's no tomorrow☔. With wind gusts this strong, I often think about packing stones in my bag! »

« The weather changes in just a few minutes. The beach and sea are deserted, all because of a summer rain. »
