Frequently Asked Questions

The weekly VanSky index for Grindavík is 26 out of 100. It is the average of the daily scores, adjusted for swings in the weather: the more uneven the week, the lower the score.

VanSky Index

A weather comfort index for travel: a 0–100 score. Recalculated daily from live weather data — temperature, rainfall, wind and sun.

80–100Ideal

60–79Comfortable

40–59Acceptable

20–39Challenging

0–19Extreme

How it's calculated:

Thermal comfort 35% — temperature + humidity

Sunshine 25% — panel charge, mood; in heat the sun is no longer a bonus

Precipitation 25% — rain → muddy ground

Wind 15% — awning, driving, noise

Extremes override all: frost, heat, storm, downpour

Heat counts by feels-like temperature: at 32°+ the score can’t reach “Comfortable”, muggy nights lower it further

A dangerous day drags the week down: a storm or downpour in the forecast keeps the week from being “Comfortable”

Bonus: warm sea, high panel output
