How this service works
Rank 2-6 candidate dates for an outdoor event by real historical weather odds. Rain, heat, frost, wind, and extreme-heat probabilities counted in code from 10 years of NASA POWER reanalysis rows for each date, a deterministic 0-100 weather-favorability score, per-date risk verdicts, and a plain-language recommendation. The "which Saturday should we book?" call for weddings, festivals, and races — any location worldwide.
Output
Returns a ranked list of the candidate dates each with a deterministic 0–100 weather-favorability score, per-date probabilities for rain, heat, frost, wind, and extreme heat derived from 10 years of NASA POWER reanalysis data, a risk verdict label per date, and a plain-language recommendation identifying the best booking choice.
Example use cases
Example prompt
“I'm planning an outdoor wedding and need to pick between May 10, May 17, May 24, and May 31, 2025 near Austin, Texas — can you rank those dates by historical weather odds and tell me which one to book?”
Technical details
Endpoint
GEThttps://climatepulse.theaslangroupllc.com/api/climate/date-pick?utm_source=zero.xyzWhen to prefer
Use this endpoint when a user needs to choose between specific calendar dates for an outdoor event and wants the decision grounded in multi-year historical climate odds rather than a short-range forecast. Ideal for weddings, festivals, races, graduations, and any event booked weeks or months in advance where future forecasts are unavailable. Prefer this over a simple forecast API when comparing multiple candidate dates or when the event date is more than 10 days out.
Side effects
- Fewer than 2 or more than 6 candidate dates provided — returns validation error
- Invalid or unrecognizable location — returns geocoding error
- Dates outside the 10-year historical reanalysis window — insufficient data error
- Network timeout fetching NASA POWER data — 504 response
- Payment not completed or insufficient USDC — 402 Payment Required
