On the other hand, summer also has disadvantages that can't be ignored. The heat in the city can be sweltering, especially without air conditioning. Public transportation becomes stuffy and crowded during rush hour. Mosquitoes, gnats, and other insects make their presence felt. For working people, vacations are still limited to two or three weeks, and the rest of the time is just business as usual. Besides, not everyone likes the heat: some people tolerate it worse than the cold.
So the answer depends on your specific circumstances. If you're planning a beach vacation or live in the countryside, summer is likely a joy. But if you're spending July and August in a stuffy metropolis office, it's understandable that you won't be particularly thrilled.
