When the wind speed goes up to 50 km/hr and above.
One time the wind gusts had a sudden increase, it went really strong which im sure it was above 50 that it could blows us, we had to really hang on something. We saw tourist from china who just got off his car were blown to the edge of the cliff, lucky he got stuck on a big branch but he dropped his super expensive set of DSLR down the cliff and his leg was injured. In the same time, his wife was so panicked that she tried to get back in the car, so she opened the car door and hangs on to it, but the wind was so strong it blew and smacked the door back and messed up the main hinge, it was really hard to close the door and it opens way wider than it used to. 😨 so if you come visit this place, be aware of the wind speed 🌬
