The agreement that governs your use of the WeatherLabs API and website. Please read it alongside our Acceptable Use Policy, Privacy Policy and Refund & Cancellation Policy.
Last updated: 12 June 2026
These Terms of Service ("Terms") are a legal agreement between you (the business or individual using the service, "you") and WeatherLabs (the operator described below, "WeatherLabs", "we", "us"). By creating an account, generating an API key, or otherwise using the API or website, you agree to these Terms. If you are agreeing on behalf of an organisation, you confirm you are authorised to bind that organisation.
The service is offered business-to-business (B2B) — it is intended for use by businesses, developers and other professional users, not consumers. If you are a consumer in the UK or EU, you may have additional statutory rights that these Terms do not remove or limit; nothing here affects those rights.
WeatherLabs is operated by WeatherLabs Ltd, a limited company registered in England and Wales under company number 17265453, with its registered office at 2 Arnewood House, Everton Road, Lymington, SO41 0HF, United Kingdom.
In these Terms:
The Service provides programmatic access to weather forecast data derived from the NOAA Global Forecast System (GFS) model, together with a website for exploring and integrating that data. The underlying GFS model output is produced by the United States National Oceanic and Atmospheric Administration (NOAA) and is in the public domain; WeatherLabs is an independent service and is not affiliated with, authorised, endorsed by, or sponsored by NOAA, the US National Weather Service (NWS), or any government agency. What we provide is the processing, hosting, transformation and delivery of that data as a service.
Beta. The Service is currently offered in beta. It is provided without any service level agreement (SLA): we do not commit to a particular level of uptime, latency, throughput, or data freshness, and the Service may be unavailable, delayed or incomplete at any time. We may add, change, withdraw or deprecate features, endpoints, variables, models or data without liability, in line with our published API stability and deprecation policy (see the API documentation). Where reasonably practicable we will give advance notice of breaking changes by email and/or via the Site.
Multiple weather models and other capabilities described as planned or "roadmap" are not part of the Service unless and until they are made generally available; we make no commitment to deliver them.
Paddle is our merchant of record. When you purchase a paid Plan, your contract for payment is with Paddle, who sells the subscription to you as the seller/merchant of record, collects payment, and handles applicable VAT and sales taxes. Paddle's own buyer terms apply to the payment transaction in addition to these Terms. We do not store your card details.
429) rather than silently billed — there are no surprise overage charges. To do more, upgrade your Plan or wait for the quota window to reset.Free and Developer Plans are provided at no charge and may be subject to lower quotas and additional fair-use limits; we may change or withdraw free tiers on reasonable notice.
Your use of the Service must comply with our Acceptable Use Policy (AUP), which forms part of these Terms. In summary, you must not attempt to circumvent quotas, rate limits or metering; must not resell or bulk-redistribute raw API responses as a competing dataset; must not abuse, overload, probe or attack the Service; and must not use the Service for unlawful purposes. We may throttle, suspend or terminate access for breach of the AUP (see section 10).
Subject to these Terms and your Plan, we grant you a non-exclusive, non-transferable, revocable licence to access the API and use the Data:
You must not:
About the source data. In the interest of being upfront: the underlying NOAA GFS model output is public domain and is available free of charge elsewhere (for example, directly from NOAA). What you are paying us for is the service — the ingestion, processing, restructuring for fast queries, hosting, reliability and the API around it — not exclusive rights to the raw numbers. Attribution to WeatherLabs is appreciated but not required. If you do credit a source for the underlying model, please attribute NOAA/NWS GFS accurately.
The Data is automatically processed numerical weather-model output. It is provided strictly "AS IS" and "AS AVAILABLE", and it may be inaccurate, incomplete, delayed, or unavailable. Forecasts are inherently uncertain and the Data is not checked, corrected or warranted by a meteorologist.
The Data is NOT suitable for, and must NOT be used as the sole basis for, any decision where errors could lead to death, personal injury, or damage to property or the environment. This includes, without limitation, aviation, marine navigation, offshore operations, search and rescue, emergency management, and the protection of life or critical infrastructure. For any safety-of-life or safety-critical purpose you must rely on official warnings and authorised meteorological services.
The Data does not constitute professional, safety, legal, financial or operational advice. You are responsible for independently verifying the Data and for any decisions you make using it. To the fullest extent permitted by law, we disclaim all warranties, express or implied, including fitness for a particular purpose, accuracy, and non-infringement.
Nothing in these Terms excludes or limits our liability where it would be unlawful to do so under the laws of England and Wales — including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot legally be excluded.
Subject to that:
Because the Service is provided in beta and without an SLA, you accept that you use it at your own risk and should not deploy it for any purpose where the consequences of error, delay or downtime are not acceptable to you.
As a business user, you agree to indemnify and hold harmless WeatherLabs against any claims, losses, liabilities, damages, costs and expenses (including reasonable legal fees) arising out of or in connection with: (a) your use of the Service or the Data in breach of these Terms or the AUP; (b) your applications or products that incorporate the Data; or (c) your violation of any law or the rights of a third party. This section does not apply to consumers.
You may stop using the Service and close your account at any time from your dashboard (which revokes your keys and cancels any subscription, effective at the end of the billing period). We may suspend or terminate your access — immediately where necessary — if you breach these Terms or the AUP, if required by law, to protect the Service or other users, or if your payment is not made when due. On termination, your right to use the Service ends and your API keys stop working; sections that by their nature should survive (including licence restrictions, disclaimers, liability, indemnity and governing law) will continue to apply.
We may update these Terms from time to time. If we make material changes, we will give reasonable notice by email to the address on your account and/or by posting a notice on the Site, and will update the "Last updated" date above. Changes take effect from the date stated in the notice; your continued use of the Service after that date constitutes acceptance. If you do not agree to a change, you should stop using the Service and may cancel your subscription.
These Terms and any dispute or claim arising out of or in connection with them (including non-contractual disputes) are governed by the law of England and Wales, and the courts of England and Wales have non-exclusive jurisdiction. If you are a consumer, this does not deprive you of the protection of mandatory rules of the country in which you live.
