14 day weather forecast

This plot displays the 14 day temperature forecast for your selected location, Guam.

The red numbers show the expected high temperature for a given day, while the blue numbers show the expected low temperature. Because forecast uncertainty increases with time, we also display the range of possible high/low temperature outcomes, shown as the shaded red/blue regions. The actual high/low temp could fall anywhere in that shaded region, and the larger the shaded regions are, the higher the forecast uncertainty is.

Forecast for the next few days - The weather forecast for Guam is available in several different versions, all clearly and simply displayed here on the Weather Guam page. For the short term, we have data based on a single weather model that is known to deliver the best forecast for Guam. For the longer term, we have forecasts for the next two weeks based on an analysis of many different possible forecast outcomes that will give you a sense of not just what's most likely, but how the forecast could change in future updates as we get closer to any given date. If the range of possible outcomes is narrow, you can have high confidence in the forecast. If the range is wide, you know there’s more uncertainty, and to not give too much credence to any one possible forecast outcome.
