#1 for good weather
Best match
The green sweet spot — lupine fields starting, near-midnight sun, pre-tourist-peak prices.

Best match
Vernal equinox = perfect aurora window; snow still on mountains, fewer tourists than peak winter.
#3 for good weather
Best match
Spring thaw, puffins arriving, no more aurora — quiet between two very different Icelands.
#4 for good weather
Best match
Midnight sun at its peak, all roads open, summer solstice festivals — and summer prices.
#5 for good weather
Best match
Still warm, Reykjavik Pride, and the very first aurora sightings returning late in the month.

Strong option
Warmest month, every road open — absolute peak for crowds and prices.
