Higher than usual Coolant Temps, but not overheating
Not sure I have a problem, but my engine coolant have been running about 10* - 15* F higher than usual, over the last 6 months (May - October). The car DOES NOT OVERHEAT and has maintained normal coolant levels. The car normally runs 186 -192*F, but I am now seeing 200*F for the past months during normal driving. The maximum temp I have seen in logs while driving is 212* I have made no changes the car over at all except I switched my brand of oil from Castrol to Total Lubricants, and it has been running in it current form for about 4 years. My car is single turbo 500+RWHP occasionally driven on weekends and has all the necessary cooling mods such as KOYO Rad and heat shields. I have checked the usual culprits such as operation of the fans, water pump fins, replaced thermostat, replaced coolant thermo-sensor.
Could it be related to higher ambient temps (GLOBAL WARMING)? Logs for last year summer were checked and the normal operating temps never got quite this high.
Any Ideas guys on what could be causing higher coolant Temps?

Do a cooling system pressure test. Could be that one of your hose clamps loosened up somewhere. Also, hose down the fins of the rad and oil coolers in case gunk accumulated there.
Beyond that, I got nothing but higher ambients do usually result in higher cooling temps given that the heat exchangers rely on air to cool the liquids running through them.

I'm hoping Its related to higher Ambient Temps.

I think it's more a cooling system issue. Have you checked your T-stat? When did you last change your coolant. Have you tested your pressure cap? Are you using a different weight engine oil? Have you checked your oil temps?
If you really believe it's related to the incoming air temps, drive around when the ambient temps are the same as when you were reading 186-192. If it's still reading 200+, you have your answer

I would check for obstruction in the air flow path - a bag sucked into the front of the car. Next thing would be a lazy thermostat or a bad cooling fan.
Could also just be the fact that it's been a REALLY damn hot summer.

moving or sitting?"
If its higher while sitting, 10/10 its the fans/voltage etc wearing down
if its both sitting and moving, most likely its ambient temps, gunk on the radiator, but could potentially be the tune/timing as well. Are you sure the tune isn't changed at all?

Update: I appears that my higher than usual coolant temperature's were related to the ambient temperature. Now that the ambient temperature is much lower. The coolant temps are now back to the normal levels.
Also, I was recently informed the July 2019 was the hottest on record.
