Weather in Lanzarote in May

Warmer than London, but not a hot-weather bet

Lanzarote's average May daytime high is 4.3°C above London's, so there is a clear improvement in warmth without a jump into intense heat. Light clothes make sense during the day, with a light jumper or cardigan for sitting outside in the evening. Even the warmer days are fairly restrained: the warmest 10% reach 22.6°C or more. This suits travellers who prefer being outdoors to planning everything around cooling off. If your main aim is reliably hot afternoons, May is less convincing. Treat it as comfortable warmth rather than summer heat, and keep something warmer handy for nights that fall below the average.

Dry days are the draw; the sea is the compromise

Rain is unlikely to shape your plans, with about 0 rainy days in a typical May. That makes outdoor time a reasonable default, rather than something to squeeze between showers. Swimming needs a different expectation: the sea averages 19.5°C, with a year-to-year range of 19°C to 20°C. It is bracing rather than comfortably warm, so May is better suited to travellers happy with a refreshing dip than those wanting to linger in the water. Bring something dry to put on afterwards. If warm sea swimming is central to your holiday, the low chance of rain does not make up for that cooler water.
