Weather History and Forecasts in Wolfram|Alpha
Does this summer seem hotter than last year’s? Are you debating between a trip to Miami or Florence in the springtime? Or perhaps heading to Tokyo in November, and wondering how to pack? Wolfram|Alpha has a number of helpful tools to answer your weather questions, by retrieving current conditions, forecasts, and historical data from weather stations located all over the world.
For example, simply enter “weather” into the computation bar, and Wolfram|Alpha’s geoIP capabilities identify your approximate location and produce the latest records from your nearest weather station. The “Latest recorded weather” pod may feature information like the current temperature, relative humidity, wind speed, and conditions, such as clear, thunderstorms, or fog. Go ahead and click here to give it a try for your area.
You can explore the “Weather history & forecast” pod further to gather information such as temperature, cloud cover, conditions, humidity, wind speed, incident sunlight intensity, and historical temperatures for a specific date. By using the drop-down box in the header of the pod, you can adjust the time window for the current day, or next week, or take a look back in time to view these conditions over the last month, last year, last 5 years, and so forth. The length of available weather history may vary by location.
Are you looking for a warm location to visit next spring? Try Wolfram|Alpha to compare the patterns of different locations. For example, if you query “Weather Florence, Italy, Miami, Florida”, Wolfram|Alpha will show comparative results for those cities.
In this particular example, we asked Wolfram|Alpha to plot weather history recorded over the past year for Florence, Italy and Miami, Florida. If you’re looking for a warm place to visit, it’s nice to know you can expect Miami, Florida to be about 9 degrees Celsius or 17 degrees Fahrenheit warmer than Florence, Italy.
Wolfram|Alpha can also give you a snapshot of a location’s climate. For example, query “climate Tokyo” and Wolfram|Alpha will graph temperatures and precipitation in Tokyo recorded between 1946 and the present. The blue area in the chart below represents the temperature range at certain times of the year over time, with the deep blue line signifying the average temperatures. If you’re planning a trip to Tokyo in November, you can likely expect temperatures to range between 10 and 20 degrees Celsius.
