Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE weather ( zip_code VARCHAR, mean_temperature_f INTEGER )
TABLE: CREATE TABLE trip ( id VARCHAR, zip_code VARCHAR )

### Question ###
Give me ids for all the trip that took place in a zip code area with average mean temperature above 60.

### Accurate SQL ###

SELECT T1.id FROM trip AS T1 JOIN weather AS T2 ON T1.zip_code = T2.zip_code GROUP BY T2.zip_code HAVING AVG(T2.mean_temperature_f) > 60
