Weather Data and Weather API Pricing

Visual Crossing Weather offers an Excel Integration that allows user to create weather queries and join weather data with their existing spreadsheet data all within the familiar Excel interface. In addition, the Weather API allows users to create a query that returns CSV data. This data can be directly imported into Excel and refreshed automatically as new weather data becomes available.

Results/day - Free plans include a limit on the number of Queries Results that can be retrieved in any 24 hour period. Note that A single 15-day forecast query counts as a single Query Result while each history record returned counts as a Query Result.

Results/query - The Records/query limit indicates the maximum number of records that may be returned by a single query. If you need more records than is indicated for your plan, you will need to break your query into multiple, smaller queries that fit below your record limit. You can typically break up a large query by breaking the time range into smaller chunks or by breaking up your list of locations.

Locations/query – The Locations/query limit indicates the maximum number of locations that you may request in a single query. If you need weather data for additional locations, you can break your query into multiple each requesting a subset of your location list. Alternately, an upgraded plan will make querying more convenient and efficient by allowing one query to retrieve data for many locations using a single request and returning a unified result dataset for all.

History summaries are powerful weather queries where the weather engine calculates a single result that summarizes many historical data records. For example, this type of query could be used to calculate the climate change for a given location by aggregating individual weather observations across multiple decades. For more information, see our documentation.

This type of query filtering allows users to specify which specific hours of the day should be included in their result data. Hours outside the specified range are excluded from all results including summaries and aggregations. Weather conditions often vary significantly over the course of a 24-hour day while businesses and other activities are typically only active during a portion of those hours. For this reason, you can get more accurate weather correlations by including only the active hours in your weather results. As an example, if a retail business is only open from 9am to 9pm, an overnight freezing temperature is likely to have a minimal effect on the foot traffic for a given day as long as the business hours temperatures are conducive to outdoor activity. However, freezing temperatures during business hours are likely to have a much greater impact. For more information, see our documentation.
