Florida suits warm-weather holidays and swimming

Florida is a strong April choice if you want warm afternoons without needing extra layers every evening. Daytime temperatures average 27°C across Florida, Miami and Orlando, so plan shade breaks if you find midday warmth tiring. Miami stays warmer after dark at 22°C, compared with Orlando at 17°C, where a light layer may be welcome. Sea temperatures of 25°C in Florida and Miami make swimming a more comfortable prospect than in New York. The catch is rain: Florida and Miami average 8 rainy days, while Orlando has 7. Keep outdoor plans flexible and pack a light waterproof rather than expecting an entirely dry holiday.

Las Vegas is drier; Hawaii has warmer evenings

Las Vegas suits travellers who prioritise dry weather over warm nights. Its 25°C daytime average is comfortable for being outdoors, and 2 rainy days make it the driest choice here. The change after sunset matters, though: nights average 12°C, so bring a jumper or jacket rather than packing only summer clothes. Hawaii also averages 25°C by day, but its 22°C nights make evenings much warmer. With the sea at 24°C, it is a better fit if swimming is part of the plan. Hawaii's catch is its 9 rainy days, so leave room to rearrange outdoor activities rather than relying on uninterrupted sunshine.

New York needs a different packing list

New York is the choice for travellers who prefer cooler days and do not need beach weather. At 15°C by day, it is only slightly warmer than London's April average of 14°C, so do not let the warmer country average shape your packing. Nights fall to 5°C, making a warm jacket useful for evenings out. It also has the most rainy days among these destinations, at 11, so waterproof footwear and an indoor alternative are sensible. The sea averages 8°C, which is cold for casual swimming. April here suits a layered wardrobe and flexible outdoor plans, rather than a holiday built around warmth.
