Rain fell steadily through much of the race, turning Monaco's unforgiving streets — barely wide enough for cars to pass even when dry — into a genuinely treacherous proposition. The circuit offers essentially no run-off anywhere: a small mistake in the wet doesn't mean a trip through gravel, it means a barrier.
Lewis Hamilton led much of the race for McLaren, driving with the kind of controlled aggression that had already started to define his reputation in difficult conditions, managing the car confidently while others around him struggled for grip on the painted lines and drain covers that turn treacherous when wet. Through the race, several competitive cars found the limit the hard way, catching the barriers at various points around the circuit as the combination of low grip and zero margin for error took its toll — a familiar Monaco story in the wet, just compressed into fewer corners than most circuits offer.
Hamilton brought his car home for the win, managing the conditions and the pressure of Monaco's unique demands better than those chasing him. It was an important, confidence-building win early in what would become his first world championship season.
