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

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.

Current weather - Here we've put together a glance at all the most important information about the current weather in Ontario (San Bernardino County, California, United States). You can see with the radar HD if precipitation is falling at the moment, or headed towards Ontario soon. You can also see where there are thunderstorms currently ongoing, as well as where thunderstorms have occurred in recent weeks and months with our lightning analysis tool. Our HD satellite images of Ontario will show you whether there’s sunshine currently in the area, or if clouds are making for a more gloomy day. Finally, current observations will tell you what current temperatures look like around Ontario at the moment, as well as if it's humid and/or windy.

Forecast for the next few days - The weather forecast for Ontario is available in several different versions, all clearly and simply displayed here on the Weather Ontario page. For the short term, we have data based on a single weather model that is known to deliver the best forecast for Ontario. 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. We also have other products such as Meteograms and Forecast XL elsewhere on our site to give you additional options for figuring out the forecast for Ontario.
