The outdoor-conditions data layer

Where — and when — outdoor conditions are reliably good.

Not an average. A floor.

Forelore turns 25 years of satellite climate record into a measured floor of pleasant outdoor hours, for any location on Earth. An audit of the record.

AVERAGE FLOOR
The average is a coin-flip. The floor is what held 24 of 25 years.
Good outdoor hours on your date, each of the last 25 years.
What we measure

Daytime hours with no rain, no oppressive heat, no biting cold.

Day by day, reported as a conservative floor: the level a place has held in at least 24 of the last 25 years. The positive, amenity side of climate data — the complement to flood, fire and heat-hazard scores.

Daytime only

The 8am–10pm window people actually spend outdoors — not a 24-hour, all-year average.

A floor, not an average

The worst-plausible level — held in at least 24 of the last 25 years (≈90% one-sided confidence) — not the typical year.

Day by day, and inside the day

Resolved to the calendar day and, where useful, to intra-day blocks: morning, midday, afternoon, evening.

25 years of measured record

NASA GPM IMERG (rain) and Copernicus ERA5-HEAT (UTCI thermal comfort), 2000–2025, on a global grid. Methodology published.

What it can power

Three ways to put it to work.

A number you can publish

A defensible "N reliably pleasant outdoor days a year" for any location — third-party and methodology-published.

Answer "when should we go?"

Best-weeks guidance from 25 years of record, not monthly averages — for any destination.

The amenity score

The reliably-good-conditions counterpart to flood, fire and heat — the side risk scores don't cover.

Flexible by design — any location, any window, any threshold, any time of day. Licensing is bespoke, discussed directly: by dataset, API, or co-branded layer.

Proven application

Outdoor event dates.

The same data already powers a consumer product that audits outdoor dates by venue and time — evidence the layer works on real decisions.
