The weather in April can be warm during the day and extremely cold overnight (temperatures may be below 0 degrees celsius). Rain and very cold winds are possible. Visitors should ensure they are adequately equipped for these extremes by ensuring that they take appropriate warm and protective clothing. See Packing for what to bring.
There is no shelter at any of the commemorative sites and visitors will be exposed to the weather for the entire period they are on site, which can be up to 24 hours. Large crowds, limited public utilities, and traffic and security arrangements can result in long waiting periods.
