My favourite beach in Spain

I must say that I haven't gone to all the beaches that we have in our country because we have many of them, but I've visited quite a few and I should say that my favourite is Playa Victoria in Cádiz.
Why am I so certain?. Because of the town and the beach itself. (Típicamente no se permite iniciar una frase con "because", pero en este estilo y modo de narración, se podría.) Cádiz is a really beautiful city in the south of Spain, totally surrounded by water except for a narrow strip that connects it with San Fernando. And of course, the beach is amazing, clean, with everything you need, it's big and relaxing (except in August). 
Well, I must say that we have great beaches in Canary Islands and in other regions of Spain, but this is my favourite.

Thanks for your help

________________
En la última frase verde, escribe "the beach is...", "it's...". Con estos, se repite el verbo "is". Debes eliminar el segundo. También, en una lista como esa, es más común que los adjetivos son similares y el diferente queda al fin. Por ejemplo: "The beach is amazing, clean, big, relaxing, and has everything you need." Finalmente, "(except in August)" es una buena adición, pero debe colocarla detras del elemento que modifica. (Me imagino que lo quiera tras "relaxing"?))

Sin embargo, me gusta el estilo de narración y el tema. Muy bien hecho! felicidades

My favourite beach in Spain

I must (better: should) say that I haven't gone to all the beaches that we have in our country because we have many of them, but I've visited quite a few and I should (better: would) say that my favourite is Playa Victoria in Cádiz.
Why am I so clear sure?. Because of the town and the beach itself. Cádiz is a really beautiful city in the south of Spain, totally surrounded by water except for a narrow strip that connects it with San Fernando. And of course, the beach is amazing, clean, with everything you need. It's big and relaxing (except in August).

Very well done. "Must," "should," and "would" have different connotations (and denotations). "Must" is rarely used, and it implies a very strong obligation to do something (or, together with the auxiliary verb "have", it can imply likelihood or probability).

"Should" is much more common, and implies a less urgent or serious obligation. For example, "I should take the dog for a walk" sounds much more normal than "I must take the dog for a walk." 

"Would," on the other hand, indicates the conditional mood, just like the verb endings -iría, -irías, etc. in Spanish. 

Keep up the good work!
