Table schema:
CREATE TABLE trip (id VARCHAR, zip_code VARCHAR); CREATE TABLE weather (zip_code VARCHAR, mean_temperature_f INTEGER)

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