2025 Tesla Model Y in Honolulu, HI
Winter range, charging cost and how far it goes, worked out for Honolulu's weather, grid and prices.
Winter barely touches range in Honolulu: at a typical January's 74°F, a Model Y gets an estimated 290 miles on a charge, within 5% of its 277-mile rating. Power is pricey in Hawaii (48.0¢/kWh), so charging at home costs about $171 a month for 38 miles a day, still less than the $241 an average small SUV costs on the West Coast's gas. Honolulu's grid (HICC Oahu) is 94% dirtier than the US average, but charging on it still makes 44% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 139 real drives of this model; the rest come from 1,548 real drives in EVs at each temperature (and Recurrent's winter study below freezing), applied to its 277-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.
