That's normal. There are two significant temperature points - the thermostat and the cooling fan. The engine can run anywhere between those once it's warmed up. On my car the thermostat is 180F, like yours. The cooling fan comes on at 206F. On a hot day and in-town driving, it can rise to 210 or so before the fan can bring the temperature back down. Highway driving keeps it cooler due to the extra airflow.
