King's Day set to be warm

The weather for Saturday's celebration of King's Day is predicted to be mild, with temperatures of 17 to 21 degrees. During the day, it might become cloudy during the day and the afternoon and evening may be interrupted with a few showers. The Royal Meteorological Institute (KNMI) is positive about Saturday. The day will start dry, with some clouding, and the sun will break through every now and then.

Weeronline expects several showers in the evening. A minimum temperature of 11-12 degrees is predicted for the evening, and the afternoon temperatures could run up to 18 degrees, making it possible that this will be the year's first 'skirt day', as defined by writer Martin Bril in 2009:

"...that one day in the Spring when all women as if by magic suddenly wear a skirt, with bare legs underneath. Up to now the definition upon which this and that can unquestionably be bargained, but I don't feel like that, stronger still; it is a beautiful definition."

The KNMI has a special website where the temperatures of the 27th of April have been recorded since 1967. The highest ever temperature recorded was in 2007, at 27.3 degrees. 1985 was extremely nippy, at just 7.4 degrees.

The warm weather will welcome the throngs of partygoers who are expected to descend on cities Saturday to celebrate the King.

Parts of Amsterdam's center will not be open to car traffic, and the public transport network will be amended. Trams and buses will not stop at Amsterdam Centraal. Travelers will have to reckon with the general train traffic changes as well. Amsterdam RAI station will be closed the entire day. On some routes more trains will alleviate congestion, while there will be less trains running  on other routes.

For the first King's Day, Willem-Alexander will be taking his family in toe in De Rijp and Amstelveen. He is taking as many Royal Family members with him, just like last year on Queen's Day.

This might be the last time that the Royal Family takes part so intensively in the celebrations. There has been extra security for royal visits. This is mostly to blame on the attack on the Royal Family in 2009 in Apeldoorn.

Now, a formula is being looked for that can alleviate these extra security costs.

The princesses are still too young to be able to walk past a group of people twice for an house. If the Royal couple wants to involve them in the party, then that has to be taken into consideration.
