Spring is the worst fucking season weather wise. It's perpetually wet and rainy, and the temperature is erratic. In the past 3 weeks it has been 55, 75, then 30, and now we are up to 80 in my part of Ohio. You cant accommodate for it, you cant plan anything outside, and my allergies go absolutely bananas. Summer is consitent, and the fall never really has wild weather changes, just a steady cooling down.
Apparently you don't live in Scotland (west coast at least).
Spring may not be warm, but we get some clear dry days, and if you're in the sun and out of the wind you can feel the heat.
By summer it's so muggy and humid that 15 degrees (Celsius) feels oppressive. I used to live in Australia but the (not-)heat here feels worse.
Rain is fine, but we have been getting floods and everything was muddy. A light sprinkling is lovely. Thunderstorms are great to sleep through. But heavy rain all week is lousy.
