Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

StormGeo

  • No longer independent as fully owned subsidiary of Alfa Laval since June 2021
  • Primarily Europe-based with less established presence in Asian maritime markets compared to Weathernews
  • Focused on commercial and industrial sectors rather than consumer weather services

Weatherstack

  • The free tier allows 100 API calls a month, which is a demo rather than a usable allowance
  • Historical weather data starts at the Standard plan, $9.99 a month for 50,000 calls
  • Forecasting is tiered: 7 days from Professional at $49.99 a month and 14 days from Business at $99.99
  • Multi-language responses and bulk queries need Professional or above
  • Going past the monthly quota incurs overage charges rather than throttling
