The Netherlands could experience its second official heatwave of 2026 next week, according to a report from Dutch news outlet ad.nl. The forecast, published on Friday, August 7, suggests tropical temperatures will arrive after the weekend.
Ad.nl reports that the upcoming warm spell may be strong enough to meet the official criteria for a heatwave. In the Netherlands, a heatwave is typically defined as a period of at least five consecutive days with maximum temperatures of 25 degrees Celsius or higher, including at least three days reaching 30 degrees or more.
The report indicates that the hottest conditions are expected to build during the early part of next week, following the weekend. The exact peak temperatures and duration of the warm period have not been detailed in the available summary from ad.nl.
If confirmed, this would mark the second heatwave of the year for the country. The first heatwave of 2026 occurred earlier in the summer, though specific dates and figures were not included in the report summary.
Weather forecasts this far out can shift, and ad.nl's report is based on current model projections. Residents and visitors in the Netherlands should monitor updated forecasts as the weekend approaches for more precise temperature expectations.
What to watch next: Whether the warm spell holds long enough to officially qualify as a heatwave, and any heat-related advisories issued by Dutch authorities.
