How it's calculated
Rainfall is summed day by day from your chosen start date through today, using real recorded daily precipitation totals for your ZIP code's coordinates.
A day counts as a "rainy day" if it recorded at least 0.01 inches — the standard threshold for measurable precipitation.
Historical weather archives typically lag ~5 days behind today, so the most recent few days may not be counted yet.
Row Wise tracks rainfall, irrigation and soil moisture balance automatically for your actual field boundary all season — plus when it's time to irrigate.

How accurate is this compared to a rain gauge?
This uses a reanalysis-based weather archive, which blends satellite, radar and ground-station data into a gridded estimate for your coordinates — it's a very good estimate for a broad area, but a physical rain gauge at your exact field will always be more precise for that specific spot.
Can I use this to check rainfall since planting?
Yes — set the start date to your planting date and it'll total everything received since then, which is useful for judging whether a field has gotten enough moisture without checking a log.
Why might today's rainfall be missing?
Historical weather archives are usually a few days behind real time. If the last day or two looks low, that's likely because the archive hasn't caught up yet, not a data error.
