New York, NY (April 13, 2026)

A dramatic weather swing is underway across New York and New Jersey as a cool start to the week quickly gives way to an unusual stretch of midspring warmth more typical of early summer. Forecasts show temperatures climbing well above seasonal norms beginning Monday, with the warmest conditions expected from Tuesday through Thursday.

After a crisp weekend and overnight lows that dipped into the 40s in parts of the region, Monday opens the door to a much warmer pattern. New York City is expected to reach the upper 70s under mostly cloudy skies, with a brief afternoon shower possible. By Tuesday, highs are forecast to move into the low 80s, and the chance for a pop-up afternoon storm increases as warmer air continues to build over the tri-state area.

The hottest part of the stretch is expected in the middle of the week. In New York City, temperatures are forecast to surge to about 88 degrees Wednesday and remain in the mid-80s Thursday, while inland communities in New Jersey and the lower Hudson Valley could run even hotter. Along the shoreline, however, the ocean will keep conditions noticeably cooler. Montauk, for example, is expected to stay mainly in the upper 60s to low 70s during the same period, highlighting the sharp contrast between inland and coastal areas.

The warm pattern is not expected to last through the full weekend. Friday should still feel summerlike, with highs near 80 in the city, but a more meaningful cooldown is projected by Saturday, when temperatures fall back into the 60s. Sunday is expected to remain mild but cloudier, and cooler air is likely to arrive by early next week.

For residents across the region, the week ahead will bring a little of everything: a reminder of spring’s volatility, a burst of near-record warmth, and then a quick return to more typical April conditions.
