16c is almost tshirt weather in northern europe, which is about same latitude as Vancouver. This would pass as a colder summer day too. No rain = beach :)
60 Farenheit is not T-Shirt Weather, it certainly is not beach weather, that's cold for a high. As far as the latitude that's fairly irrelevant thanks to the Atlantic Drift, Great Britain is at the same latitude as Southern Alaska though their climate is quite different
Everybody's perspective is different...
