Question of the Day!

I prefer cool and not-dusty, therefore:

May and September-October (and sometimes February) where I grew up. Worse: June and August, December-January.

April-May and October in W Montana. Worst: Smoke Season, July-August, Dec15th-Jan15.

June-July and December-January-February in Costa Rica. Worst: April, October.

July and November-December-January-February in Thailand. Worse: April-May.

Tromsø, Norway: Jan15th-Feb10th and August.
Tallinn, Estonia: Spring and Dec15th-Jan15th.
Iberia: spring and probably autumn. Worse: summer.

England: anytime is great if my friends are trying to kill me with a full English breakfast.

Ireland: I like wet, cool and green. Serve me colcannon.

Svalbard: I've never been (friends have); but one doesn't go there for the weather.
