Frequently Asked Questions

The weekly VanSky index for Royal Oak is 25 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. Above 60 means comfortable conditions for staying, below 40 means it is worth looking elsewhere. The 7-day forecast is further up this page.

Today a 500 W panel setup will produce about 0.5 kWh in Royal Oak. The estimate uses the cloud forecast and the length of daylight. Set your own panel power with the “My panels” control at the top of the page and the figures will update.

The daily score for Royal Oak combines thermal comfort (temperature and humidity) at 35%, sunshine at 25%, precipitation at 25% and wind at 15%. Frost, storms, extreme heat or heavy rain pull the day's score down sharply. The weekly score is the daily average, adjusted for swings in the weather.

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
