Looking for a great beach town with excellent surfing

Hello Everyone,
We are a couple moving from Redondo Beach, CA.  Previously we lived in Bend, Oregon and Seattle, Washington.
We are close to semi-retirement and looking for a great beach town with excellent surfing.  My husband has been surfing all his life and is hoping to walk to the beach and ride waves every day.   I know that I'd prefer a less humid and cooler temperature, but in the end, good surfing will have top priority I believe.
I'd like to make new friends and enjoy social events with other expats.  I'd also like to travel around Ecuador on short trips with a group of friends, after we're settled. 
We think we'd like to lease a beachfront apartment or condo, and we need to find a pet-friendly situation, as our cats are coming along.  Because of the 2016 earthquake, I'd like to know if the buildings have codes for stabilization in earthquakes.  Is there a major fault zone on the coast of Ecuador?
If any surfers are reading, what beaches are great for an athletic advanced surfer... and which have the least water pollution?  A very big concern to us is the quality of the ocean water and this will be a huge factor in where we choose to live.  Do any of the towns use sewage treatment plants, or is raw sewage commonly directed into the beach areas?  The reason I ask, is my husband became very sick on a trip in Mexico at a very popular sufing destination and we had to ask a doctor to come to our hotel twice.  Fortunately he recovered quickly with no long-term health issues.
Thank you for the warm welcome!
Looking forward to meeting interesting new friends!
Best regards,
Myrna Minkoff
