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
