The highs in June of '99 at Vancouver airport was 18C, in July it was 21C and the temperature in August was a normal 22C.
If people knew anything about the normal temperatures of Vancouver then they wouldn't have been surprised about the what the summer of '99 was like as it was just a normal summer for Vancouver.

Vancouver Climate Data For August of '99
In defense I will say that the west coast experiences much smaller variations in temperature from year to year, due to being heavily influenced by the Pacific Ocean.
So what this means, is that to the average Vancouverite two months in a row in the summer where the average temperature is 1 to 2 degrees below normal will feel like a cool summer, while on the other hand, of the 1999 temperatures were a high of 20 for June, 23 for July and 22 for August (creating the exact flip situation) many people here would remember it as a warm or "hot" summer.
The further one goes inland, the more extreme the year to year variatins become from year to year.
YVR Airport: Cool summer = 1 to 2 degrees below normal, Hot summer = 1 to 2 degrees above normal
Abbotsford: Cool summer = 2 to 3 degrees below normal, Hot summer = 2 to 3 degrees above normal
Kamloops: Cool Summer = 3 to 4 degrees below normal, Hot summer = 3 to 4 degrees above normal.
Of course this is just a simple generalization, everyone has their own personal experience.
And we have to remember that temperature is just one variable, if i remember correctly, while the temperature was near normal (a little cool) during the summer of 99, there was also much higher than normal cloud cover and foggy days. In fact this last July was the perfect example, while the temp was only a little below normal, the persistent cloud cover and rain made it feel that much cooler (when considering July is usually a very dry and sunny period in Vancouver).
