We use AerisWeather for mapping and have 3 options for forecast data:

• Apple Weather (10 day forecast and 10 days of hourly)
• AerisWeather (16 day forecast and 15 days of hourly)
• AccuWeather (15 day forecast and 5 days of hourly)

We’ll be adding more forecast sources over time. Let us know which forecast source you find most reliable in your area: support@contrast.co
