Every city at once, with and without flying: where is hot in March.
The 10 warmest places within 15 hours of London
Ranked on warmth in March alone, among well-known places (a Wikivoyage travel guide and at least 40,000 Wikipedia readers a year), one per area and at most three per country. The carbon is shown, not used to choose: the list further down is the other question, how much warmth each extra kilogram buys.

≈ is the model's estimate (air times include getting to and through the airport); ✓ is a rail journey checked against a real timetable, with the date it was checked. Temperatures are historical daily means for 2023–2024, averaged across day and night, so afternoons run warmer.
The low-carbon trade-off
The warmest place you can reach from London in March within 15 hours is Kom Ombo, 23.6 °C, costing 962 kg CO₂e return. The lowest-carbon option is Calais at 4.5 kg — 214× less carbon, for 15.3 degrees less warmth.
Every destination here is on the efficiency frontier: nowhere else this site covers is both warmer in March and lower in carbon. Anything a better option beats outright has been left out.
By rail or ferry By air
What the 15-hour limit costs: at this budget Castellon can only be reached by air — 322 kg CO₂e, in 5h 12m. Allow up to 24 hours and the train does the same journey for 37.8 kg in 16h 36m — 9× less carbon for 11h 24m more travelling.

The flights, in practice
The model measures to the town, not to a runway. For the destinations above reached by air, this is the nearest airport, how far it is, and whether a direct flight from London is listed on the airport's own destination page (researched 2026-09-15; route existence, not availability on a date). "Not checked" means no destination list was read for that airport.
| Destination | Airport | From town | Direct from London | Onward |
|---|---|---|---|---|
| Castellon, Spain | Castellón CDT | 30 km | yes STN — The airport lists the London Stansted route as year-round. | Airport bus or taxi to Castelló de la Plana. |
| Alzira, Spain | Valencia VLC | 45 km | yes LHR, LGW, LTN, STN | Metro lines 3 or 5 to Valencia, then Cercanías train to Alzira. |
| Almería, Spain | Almería LEI | 9 km | yes LGW, LTN, STN | Aena lists bus line 30 between Almería, the airport and Retamar. |
| Metlaoui, Tunisia | Tozeur–Nefta TOE | 55 km | not checked | Road transfer from Tozeur; Gafsa Airport's current scheduled service was not established. |

Warm is not the same as pleasant, which is why sunshine and rainfall are shown alongside temperature. All three are ERA5 monthly means for 2023–2024.
Where the curve breaks
The frontier is gentle until it isn't. Going from Taroudant (616 kg, 20.9 °C) to Akhmim (902 kg, 21.7 °C) buys 0.8 °C more warmth for an extra 286 kg — 357 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.
The pick of them

March answers differently depending on what you are after, and the lists genuinely diverge: the brightest places are not the hottest, and in summer the useful question stops being where is warm at all.
