Sir if your temperature needle remain at half way mark or slightly higher, its normal, it also occurs in my 05 Civic.
Is your Fan A/T, is it running with proper speed, clean the dust or carbon, if any.
Also check the heat range of your spark plugs, with mostly unleaded petrol that we have in Pakistan spark plugs heat and get dirty very quickly.
Also service the radiator and use the Honda long life coolant, its already premixed so you do not have to do anything.
