Get the weather data you need into your systems

HortPlus provides Managed Weather Data Services and Weather Data API access for commercial and research users who are after high-quality and reliable data.

Our weather data is sourced from the HortPlus Weather network, a network of scientific-grade weather stations covering all the major horticultural growing areas in New Zealand. We also have access to other weather data networks.

Horticultural Weather Station Network

All of our stations are professionally installed, or have been installed by one of our partners to scientific or WMO (World Meteorological Organisation) standards. We maintain historical data sets for all stations with periods of up to 20 years.
HortPlus manages a network of research-grade weather stations covering all the major growing areas of New Zealand. All of these weather stations provide hourly data that is loaded into our weather database.
You can make use of our weather data in GIS and research applications, overlaying data and running data analytics to develop new tools and models.
If you have access to existing weather stations & hardware these can be added to our network to build a tailored private network to meet your own needs. Uses for this might include research trials or specific projects where a single source of managed data is important.
We provide programmatic API access and easy web-based platform access to our weather station network.

Weather Data API Access

We provide a secure Weather Data API for programmatic access that can handle a high throughput and can be directly integrated with PowerBI Dashboards, existing apps and web services, and used to pull data in for commercial & research tools.

We provide comprehensive API documentation and support for getting up and running with our Weather Data API and integrating it with your systems and pipeline. This includes a standard python and PHP library for bootstrapping projects, and we are also able to offer consulting services to help develop your integration.

Web Weather Data File Access

You can access the MetWatch Platform directly to view and export weather data yourself. You can create individual exports of data for specific variables and periods in a standard CSV format.

Managed & Curated Weather Data

Our weather data is curated and monitored to provide a consistent and truthful data set. We perform bi-weekly data checking, cross-referencing and validation to ensure that the data is consistent.

Our weather data curation and management is trusted by organisations such as Plant & Food Research, New Zealand Apples and Pears, and Onions New Zealand.

Our stations are regularly calibrated and maintained, with standardised installation and siting of all locations. All of our stations are GPS mapped with installation photos and servicing records held on file.

We keep a full record of raw, and patched weather data as well as raw data inputs.
