Averaged across 5 recent years on file (2021–2025), not the full archive — a deliberate cost/precision tradeoff, same reasoning as the site's other multi-year summaries. "Growing season" is the longest run of days with a daily average temperature at or above 5°C; dates are approximate, averaged across those years rather than tied to one specific year.
