Dear readers,

Why is it that websites about the weather never show the correct situation? I am currently in Pattaya and the weather is beautiful with sun and nice and warm. According to Weeronline.nl, rain will fall in Pattaya just like yesterday, but yesterday it was dry and today I don't believe it at all.

If you believe the weather forecast of those kinds of websites, it rains almost every day while not a drop falls.

How is that possible?

Regards,

sjors

    It does not take into account the fact that Pattaya is conveniently located on a curve, making Pattaya one of the drier places in Thailand.
    If you go towards satahip and beyond, the chance of rain is much greater.

    Vlissingen has the same effect in the Netherlands, but you never hear from the weather forecast that if it rains in Zeeland, Vlissingen will remain dry

    Take a look at the Thai version of Buienradar: http://weather.tmd.go.th
    Not as nice as the Dutch version, but accurate.

    It is better to look at the calendar when it rains than to believe the weather online.
    The end of the rainy season is mid-October and you have to be indoors between 5 and 6.00 am.

    check out Thailand's site: TMD.go.th/English this shows the different provinces and 1 or 7 days

    If I want a weather forecast in Belgium or the Netherlands, I look for a Belgian or Dutch site.

    When it rains in the Netherlands, it is often a front that will cross the country from the west. You can see that coming, and it is often large enough to 'serve' the entire country.
    In Thailand it is much more often showers that arise locally due to the heat and that you therefore do not see coming. And once they have formed, they often disappear quickly. Coincidence therefore plays a more important role per location.
    When rain is predicted in Thailand as a result of a tropical depression or a (former) typhoon, the rain will generally fall in more places and thus be more predictable, although the force usually wears off once the remnants have reached Thailand and also in this case the rain zone is often not contiguous.

      Rainwater = rain radar.

    Here is another overview of the rain in the past 30 days in Pattaya:
    In the first 20 days it rained on 16 days. So something almost every day. In the last 10 days only 1 day of rain. Could be just the other way around in Sattahip.

    The fact that such a rain shower near Pattaya sees more bends than 20 kilometers away and then thinks 'let me just stop it for a while' doesn't want to be accepted by me.

      Due to the location of pattaya (as well as Vlissingen) and the influence of the sea, the clouds blow away sooner and the gulf stream may also have something to do with this.

      As a result, Pattaya is one of the places with the fewest showers. While it may rain further down the road.

    It doesn't really work with the pictures :.

    Hi Sjors,
    If you check the website of the Thai Meteorological Department (www.tmd.go.th) and look up the place where you are, you will get the current weather for that place. You can find the weather forecast under “HOME”, both the daily and the weather forecast for the coming week. These expectations are per very large region and are reasonably predictive for that very large area. Keep in mind that the Thai weather can change very quickly, especially during the rainy season.
    The Thai weather is much more difficult to predict per place than the Dutch weather, partly caused by the many mountains and hills.
    From mid-October, now, the weather becomes more stable, which continues until March/April, after which it becomes more difficult again.
    There is a big difference in quality between the many weather websites. Reliable are the TMD for the big picture and the Dutch “weatherPro”.
    Just give WeatherPro a try, every few hours it may change, but it often comes out.
    Wishing you lots of nice weather in Thailand.
    To be.
