We are so close to the equator here that we don't really have the equivalent of 4 seasons. Rather just a 'wet' and 'dry' season. Probably about a 15 degree C variation in temperature throughout the year.

My point was that I don't believe Alaska ever got warmer than we ever do here, but it has happened. My first story about the 70 degree variation in temperature is more the norm.

for reference (for everyone else). Darwin is 12 deg south of the equator, which makes it closer than Hawaii/Honolulu (which is 21 deg north), or Nicaragua which is roughly the same at 12 deg north. Darwin is typically hot and humid.

A quick google for "Anchorage climate chart" shows that that expected maximum temperature even during summer months is about 20°C. That's quite far away from 30°C. According to the weather forecast about 25°C are to be expected. Doesn't seem healthy.
