FishRadar Global Bite Index — daily, by country

A daily "bite index" (0–100) for recreational fishing conditions, computed every night by FishRadar across ~650 tracked fishing spots in 28 countries, and aggregated here as per-country daily means plus a global mean.

The index fuses live sea-surface temperature, current, chlorophyll, tide, moon phase, barometric pressure, wind and waves into a single per-spot score (methodology: https://fishradar.ai/methodology). All values are FishRadar's own computations — no third-party data is redistributed.

• —Temporal coverage: 2026-06-19 → 2026-08-20 (63 days; updated periodically from the nightly run)
• —File: bite-index-daily.jsonl — one row per day: day, global (mean 0–100), n (spots scored), countries ({ISO2: mean})
• —License: CC-BY-4.0 — cite "FishRadar (fishradar.ai)"

Long-format CSV (day,country,bite_index,spots_scored) in three lines:

const rows = require('fs').readFileSync('bite-index-daily.jsonl','utf8').trim().split('\n').map(JSON.parse);
const out = ['day,country,bite_index,spots_scored'];
for (const r of rows) { out.push(`${r.day},GLOBAL,${r.global},${r.n}`); for (const [c,v] of Object.entries(r.countries)) out.push(`${r.day},${c},${v},`); }

What feeds the index, explained for humans:

• —Tide timing (the strongest single driver in coastal spots): how to read tides for fishing, plus live NOAA tide tables for 51 US fishing spots
• —Incoming vs outgoing tide — which half actually bites
• —The newest signal FishRadar ships: FishRadar Ear, on-device detection of the sounds fish actually make (do fish make sounds?)
