How much rain is 200cm

Posted by dvgainer on 28/3/2006 at 05:16

I'm trying to decide whether to go to Railay, and maybe Ko Yao, for 4-7 days in June. I've read that it rains about 100 cm more there than on the Gulf side, but I can't really relate that number to anything (outside of it sounding like a lot of rain). Is all day rain common, or is it more of a nice in the morning storm in the afternoon pattern. Should I expect the beach currents to be bad? Both places are somewhat protected...I'd expect the water to be muddier, but would I be able to get in a couple hours of swimming or lazing per day? Would the begginning of the month be better than the end?

Any thoughts would be appreciated (especially from anyone that can accurately and precisely predict the weather). Thanks

That 100 cm translates to about 40 inches of rain, if that helps. Is that 100 cm you mention per year? That month? What? During the monsoon season, the rain comes in from the west via the Andaman Sea. That's why the west coast, and places like Phuket and Krabi get so much rain at that time of year. The islands in the gulf, like Samui, tend to be drier, meaning it will rain less, but it will still rain.

The monsoon is hard to predict. Sometimes it will be in full swing by early June, and other times it won't get started until much later than that. World weather patterns have been pretty odd these past few years, which makes it even harder to predict. Having said that, earlier in June at least gives you a better chance of less rain than later in the month, but not a guarantee. How's that? Clear as mud, right?

I've spent about six rainy seasons in Thailand. Typically, the rains will come in the later afternoon, as the heat builds up. I remember one year I could almost set my watch by the regular downpours every day at 4 pm. Showers can last from a few minutes to a few hours. It usually doesn't rain all day long either, although it can from time to time. I remember once in Lop Buri where it rained really hard for 3 days in a row.
Keep in mind that this is pretty warm rain in any case, so getting wet isn't all that awful, particularly if you are relaxing near your beach hut.

Hope that helps.

I was comparing the rain in June between Krabi province and Ko Samui. Of course I got the units wrong (mm instead of cm). Thanks for the post. I think I'll probably check out Krabi unless a couple weeks of travelling has me more concerned about keeping dry.
