Climate version

climate-v1.1-1995-2024

• These are 30-year averages, 1995–2024, sampled at each destination's registry coordinates. They are NOT a WMO standard normal, and they are NOT a forecast.
• Celsius, rainfall and wet-day values are transcribed exactly as supplied. Fahrenheit is derived from Celsius, never supplied.
• 17 destinations: monthly values from Open-Meteo climate reanalysis, transcribed as supplied.
• 4 destinations (Jarabacoa, Constanza, Juan Dolio, Punta Rucia): computed by Transekur from Copernicus ERA5-Land hourly reanalysis (CC-BY 4.0), 1995–2024, aggregated over local Santo Domingo calendar days; a wet day is ≥ 1.0 mm.
• Values represent ~9 km reanalysis grid cells: Jarabacoa 19.1,-70.6; Constanza 18.9,-70.7; Juan Dolio 18.5,-69.4 (inland representative cell a few km from the beachfront — the coastal cell is ocean in this dataset); Punta Rucia 19.6,-71.3.
• Mountain grid cells can sit above town centers, so in-town temperatures can run warmer than the grid average. Reanalysis is modeled data, not station observations.
• Wet days for the 17 Open-Meteo destinations are days with measurable precipitation as supplied by that source; that baseline does not define a millimetre threshold, so none is stated for them.
