Weather | Chora

Four endpoints that answer “what will the elements be doing while my guests are here?” All four share the same argument shape — ?lat=..&lng=..&start=YYYY-MM-DD&end=YYYY-MM-DD — so you can request them in parallel and render whichever apply.

Endpoints

Weather

Daily forecast within 16 days, climatology (10-year historical average) beyond. Same shape either way; a mode field tells you which.

Sunrise & sunset

Sunrise and sunset times for each day of the stay. Useful for photography timing, early-arrival planning, and setting daylight expectations.

Marine

Sea surface temp, wave height, swell. Coastal only — inland coords return applicable: false.

Snow

Snowfall + snow depth for the stay. Alpine only — properties with no historical accumulation return applicable: false.

Example: compose all four in parallel

const params = new URLSearchParams({ lat, lng, start, end }).toString();
const [weather, astronomy, marine, snow] = await Promise.all([
  fetch(`/v1/pulse/weather?${params}`,   { headers }).then(r => r.json()),
  fetch(`/v1/pulse/astronomy?${params}`, { headers }).then(r => r.json()),
  fetch(`/v1/pulse/marine?${params}`,    { headers }).then(r => r.json()),
  fetch(`/v1/pulse/snow?${params}`,      { headers }).then(r => r.json()),
]);
const applicable = [weather, astronomy, marine, snow].filter(s => s.applicable);
