The first thing you should check during your stay is the weather in Baguio. The temperature will range from 15 degrees to 20 degrees Celsius, but remember that temperatures can drop lower especially in the early morning and late evening.
Your clothes should keep you warm
but not too hot. The best approach is to layer your clothes so that when it gets warmer, you can just take off some of the layers. Depending on where you are located, it is also best that you wear clothes that are not too tight. You may end up sitting on the side of the street (along Session Road) for most of the spectacle.
The parade usually starts at 8:00 AM and lasts until noontime, so an umbrella, a sun hat, or sunglasses would come in handy when you are under the mid-morning sun.
