Halfway between the Equator and the North Pole, Saint Croix Island IHS is exposed to weather conditions typical of the eastern Maine coast. In general, you can expect the following conditions:

• Spring - Temperatures are cool, with occasional fog later in the season.
• Summer - Rain is common, with some fog early in the season. Onshore breezes often make the area seem cooler than a temperature reading in the 70s and 80s Fahrenheit (21-27 degrees Celsius) might indicate.
• Winter - Temperatures are moderate, with snow possible from October through March (sometimes later).

When you visit, it is best to be prepared for any weather, as conditions change frequently.
