Big Waves for Surfers

Surfers are always searching for the next big wave. Here is Garrett Mcnamara in Portugal this week

At GCSE we need to know

A/ “why were the waves so big?” there are 3 reasons:

  1. The strength of the wind (it was over 100mph at times)
  2. The length of time the wind has blown (the storm in Portugal had  blown for a few days already)
  3. the ‘fetch’ which is the distance over which the wind has blown. This aid is Westerly and there are 1000’s of miles of Atlantic ocean out to the west of Portugal

B/ “is it a destructive or constructive wave?”… to answer this read this BBC Bitesize page  and then look back at the video

 

Here are some more photos of the waves at Praia do Norte in Nazare, Portugal. Taken by Rafael Marchante.
