Weather Data Download for Honolulu International Airport Hawaii, United States

We offer two related but separate data products: averages and history. The averages data are normals over the entire reporting period from 1980 to 2016. The history data are historical records from raw observations made at airports.

Above all, you should think of the data download feature as downloading data that you have already found and inspected on the web pages of the site. We do not have data that we are failing to show on those pages. There is a precise one-to-one mapping between what you find on our pages and what you will find in the CSV files you download. Do not assume that we 'must have' had a data field in order to compute something else that you see. For the history data, you should also not assume that because we have a certain type of data for one location, we must have it for another. You will only get what you see on the pages.

Details

Averages Data

The averages pages & data are normals over the entire reporting period from 1980 to 2016. That is, a single statistical year is presented that represents the typical weather in that location at any point in the year. In order to use conventional date formatting in the CSV file, we have to pick a single year to represent the entire period, which we have chosen to be the current year, 2024.

To take an example, the averages page for Rome tells us that the average high temperature from 1980 to 2016 on August 5th is 88°F. These pages & data do not have averages for each historical day, month, or season. For example, there are no data fields for May of 2010, just an average over every May in the entire reporting period of 1980 to 2016.

The averages pages & data derive from a variety of data sources that you can read about in the Data Sources section of each page.

The data contained in the CSV files that you can download for our averages pages are exactly and only the data that you see in the charts on the corresponding averages pages. The averages are broken down into hourly, daily, and monthly averages, with a single record given for each hour, day, or month of the typical year. You can read the specific data fields available in the Averages Data Documentation section below.

We charge 100 credits for the download of all of the averages data for a single location.

History Data

The history pages & data are historical records from raw observations made at airports. These data are inconsistent and irregular, and should be reviewed on the corresponding pages before purchasing.

For example, here is the page for the weather data we have for the Rome Ciampino Airport for 2022. If you review that page or any of the season, month, or day pages linked to on that page, you will see that there are no records of the quantity of precipitation that fell at that airport. That is because that airport did not report liquid precipitation measurements in its aviation METAR reports, so we don't have access to such measurements. In contrast, if you go to the corresponding page for Minneapolis, you will see complete liquid precipitation records. It is fairly common for airports outside the United States to not report liquid precipitation measurements in their aviation METAR reports.

Please note that you should pick a specific airport that you wish to get data from rather than relying on the choice made by our site when picking a city location. Each airport reports data differently and you may find that a different airport than the one chosen by our servers better suits your needs. Once you have purchased access to the history data for a given airport, you can download each year for no additional charge by clicking on the year link shown. If a year link is missing, that is because we do not have any data for that year. And just because a year link is there, it does not mean we have a complete year of data. You will need to look at the corresponding history pages for that airport to see if we have the data that you are looking for.

History data is reported on a per-observation basis, and with a daily summary. The observations are typically made hourly, but they are sometimes made more often, sometimes less often, and sometimes with systematic gaps, such as when airports close for the night and no observations are recorded until they reopen in the morning.

You can read about the specific data fields that are included in the history CSV downloads in the History Data Documentation section below. As I mentioned above, please keep in mind that just because a data field is listed in the documentation, that does not mean it is available for a given observation or daily summary. Always look at the corresponding history page to see that the data is present.

We sell these raw historical records on a per-airport basis for 25 credits per location.
